Laser Finishing Supplies for Beginners: Dad’s “Stay in Your Lane” Guide

If you have ever finished a laser project and thought, “Now what do I spray on this little guy?” — welcome. You are our people.

Around here, laser finishing usually starts with me saying something innocent like, “Hey Dad, can I use that tool?”

And then Dad gives me the look.

You know the look.

The one that says, “That is not a beginner tool, please step away from the professional finishing equipment before you turn this nice wood sign into a crime scene.”

So this list is our happy middle ground.

It is for laser beginners, xTool owners, class students, craft-room makers, Etsy sellers, and anyone who just engraved something cute and now needs to know what to spray, wipe, oil, sand, seal, glue, clean, or absolutely leave alone.

Dad’s official position is that there are about 47 ways to finish a laser project, depending on the material, the weather, the moon phase, whether it is going outside, and whether you are trying to make a quick class project or a fancy piece that looks like you have “a guy” in the back with a spray gun.

We do, in fact, have a guy in the back with a spray gun.

His name is Dad.

But for the rest of us, here is the beginner-friendly version of what to keep on hand after your laser is done doing its little magic show.

Dad’s Finishing Rule: Match the Finish to the Job

Dad’s answer to almost every finishing question is, “Well… what are you using it for?”

Annoying? Yes.

Correct? Also yes.

A quick indoor ornament does not need the same finish as an outdoor porch sign. A charcuterie board does not need the same finish as a decorative door hanger. A cast iron burger press does not need the same treatment as a piece of plywood you cut on your xTool.

So before you grab a random spray can and hope for the best, ask yourself:

  • Is this going indoors or outdoors?

  • Will people touch it a lot?

  • Is it decorative or food-safe?

  • Does it need to be quick, pretty, durable, or all three?

  • Am I making one cute class project or a product I plan to sell?

Once you know the answer, choosing the finish gets a lot easier — and Dad is slightly less likely to tell you to back away from the spray gun.

Before You Laser: Sealing and Sanding Wood for Easier Cleanup

Here is one of those little shop lessons that makes laser life much easier: sometimes the best finish starts before you ever hit start on the laser.

If you are working with wood, especially for signs, ornaments, class projects, or anything with detailed engraving, a little prep work can make your final piece cleaner, smoother, and easier to finish.

Plywood can be smoky, splintery, fuzzy, or blotchy depending on the quality of the wood, glue, grain, and how dramatic it feels like being that day. Prepping it first helps reduce cleanup and gives your finished project a more professional look.

Basic Beginner Wood Prep

Before lasering wood, you can:

  • Lightly sand the surface with a sanding block.

  • Wipe off the dust with a microfiber cloth or tack cloth.

  • Add a light coat of sanding sealer, clear spray, shellac, or your preferred pre-finish.

  • Let it dry completely.

  • Lightly sand again if needed.

  • Mask the surface with transfer tape if you want extra smoke protection.

  • Then laser, engrave, or cut your project.

The goal is not to build up a thick finish before lasering. The goal is to seal the top fibers just enough that smoke, residue, and paint do not soak in as badly.

Why Seal Wood Before Engraving?

Sealing wood before engraving can help:

  • Reduce smoke staining.

  • Make cleanup easier.

  • Keep paint from bleeding into the wood grain.

  • Help engraved areas look cleaner.

  • Make sanding after lasering easier.

  • Give class projects a better finished look.

  • Save you from scrubbing one tiny ornament like it personally offended you.

This is especially helpful if you are making a lot of the same item, like ornaments, name signs, tags, craft kits, or class projects.

When to Pre-Seal Wood

Pre-sealing is helpful for:

  • Light-colored wood

  • Baltic birch-style plywood

  • Draftboard

  • Painted wood blanks

  • Detailed engraved designs

  • Projects you plan to paint-fill

  • Items that will be handled a lot

  • Class projects where you want easy cleanup

If you are testing a new material, make a sample first. Some coatings can change the way the laser engraves or cuts.

When Not to Overdo It

Do not get carried away with heavy coats before lasering.

Too much finish can:

  • Make the surface gummy

  • Create more fumes

  • Affect engraving quality

  • Make cutting less consistent

  • Leave residue on the laser bed

  • Cause weird discoloration

This is where Dad would probably say, “Easy there. We are sealing plywood, not frosting a cake.”

A light coat is usually enough.

Sanding Before and After Lasering

A simple sanding block is one of the cheapest tools that makes the biggest difference.

Before lasering:

  • Use 180 or 220 grit to smooth the surface.

  • Sand with the grain when possible.

  • Wipe off all dust before engraving.

After lasering:

  • Use 220 or 320 grit for light cleanup.

  • Be gentle around engraved details.

  • Sand edges to remove rough spots.

  • Use a small sanding block for flat areas.

  • Use folded sandpaper for small corners.

If there is smoke residue, try cleaning before you aggressively sand. A light mist of hydrogen peroxide, LA’s Totally Awesome, a microfiber cloth, or a magic eraser may remove the residue without sanding away detail.

A Simple Wood Workflow for Beginners

For an easy beginner-friendly plywood workflow:

  1. Sand the plywood lightly.

  2. Wipe off dust.

  3. Apply a light sanding sealer or clear spray if desired.

  4. Let it dry fully.

  5. Mask with transfer tape if smoke staining is a concern.

  6. Laser engrave or cut.

  7. Remove masking.

  8. Clean with hydrogen peroxide, LA’s Totally Awesome, or a soft cloth if needed.

  9. Lightly sand edges or surface.

  10. Add your final finish.

This little bit of prep can take a project from “cute but crusty” to “oh wow, you made that?”

Laser Finishing Supplies Every Beginner Should Keep on Hand

One of the most common questions new laser owners ask is, “What do I put on my project after I engrave or cut it?”

And the honest answer is: it depends on the material, the use, and how fancy you want to get.

If you are making a quick beginner project, a simple clear spray finish may be all you need. If you are making a higher-end sign, gift, cutting board, display piece, or outdoor item, you may want to take a little more time with sanding, sealing, oiling, or multiple finish coats.

Here is a beginner-friendly list of laser finishing sprays, oils, cleaners, glues, and helpful shop tools we like to keep nearby.

1. Clear Spray Finish

A clear spray finish is the easiest place to start for most beginner laser projects.

Use it for:

  • Wood signs

  • Laser-cut ornaments

  • Engraved plywood projects

  • Decorative home decor

  • Painted wood blanks

  • Quick class projects

Why we like it:

  • Beginner-friendly

  • Easy to find

  • Dries faster than brush-on finishes

  • Helps protect the surface from fingerprints, dust, and light handling

Good options to look for:

  • Matte clear spray

  • Satin clear spray

  • Gloss clear spray

  • Acrylic clear coat

  • Spray polyurethane

Beginner tip: Satin is usually the safest finish if you are not sure what to choose. Matte can look soft and modern, while gloss can make colors pop but also shows imperfections more easily.

2. Spray Polyurethane

Polyurethane is a stronger protective finish than a basic clear coat and is a great option when the item will be handled more often.

Use it for:

  • Wood signs

  • Shelves

  • Trays

  • Door hangers

  • Decorative boards

  • Items that need a little more durability

Things to know:

  • Water-based polyurethane usually dries clearer.

  • Oil-based polyurethane can add a warmer amber tone.

  • Spray polyurethane is easier for beginners than brush-on polyurethane.

  • Brush-on polyurethane can be stronger, but it takes more patience.

Beginner tip: Use light coats instead of one heavy coat. Heavy coats can drip, bubble, or stay tacky longer.

3. Outdoor Polyurethane or Spar Urethane

If your laser project is going outside, do not rely on a regular indoor clear coat.

Use it for:

  • Porch signs

  • Outdoor door hangers

  • Garden markers

  • Patio decor

  • Outdoor business signs

  • Seasonal yard or porch decorations

Why it matters:

  • Outdoor projects need more protection from sun, rain, humidity, and temperature changes.

  • Indoor lacquer or basic clear spray may look great at first, but it will not hold up as well outside.

Good options to look for:

  • Exterior polyurethane

  • Spar urethane

  • Outdoor-rated clear spray

  • UV-resistant clear coat

Beginner tip: Outdoor finishes usually take longer to dry and cure. Give them time before packaging, stacking, or hanging outside.

4. Lacquer Spray

Lacquer is a beautiful option when you want a smoother, more professional-looking finish.

Use it for:

  • Higher-end wood signs

  • Decorative plaques

  • Display pieces

  • Finished wood decor

  • Items where you want a polished shop-made look

Why makers like it:

  • It builds nicely in thin coats.

  • It can give a smooth professional finish.

  • It works well with sanding sealer.

  • It dries fairly fast compared to some other finishes.

Things to know:

  • Lacquer is not usually the best choice for outdoor items.

  • Humidity can affect the finish.

  • Good ventilation is important.

  • It may take several coats for a really nice result.

Dad’s shop note: If you want a professional finish, this is where sanding sealer plus several coats of lacquer can make a big difference.

5. Sanding Sealer

Sanding sealer helps prep wood before the final finish. It seals the grain so your topcoat lays smoother.

Use it for:

  • Raw wood

  • Plywood

  • Hardwood signs

  • CNC-routed projects

  • Higher-end engraved pieces

  • Projects where you want a smoother finish

Why it helps:

  • Seals open wood grain

  • Makes sanding easier

  • Helps final coats look smoother

  • Can reduce blotchiness

  • Gives a more finished professional look

Beginner tip: Spray or brush on sanding sealer, let it dry, sand lightly, then add your final clear coat or lacquer.

6. Cutting Board Oil / Mineral Oil

For food-contact wood items, skip regular sealer and spray finishes and use food-safe finishing products.

Use it for:

  • Cutting boards

  • Charcuterie boards

  • Wooden spoons

  • Serving boards

  • Food-safe engraved kitchen items

Good options to look for:

  • Food-grade mineral oil

  • Cutting board oil

  • Butcher block conditioner

  • Cutting board wax

  • Beeswax and mineral oil blend

Why we like it:

  • Easy to apply

  • Brings out the wood grain

  • Helps keep boards from drying out

  • Safer choice for kitchen items than regular clear sprays

Beginner tip: Flood the board with oil, let it soak in, wipe off the excess, and repeat as needed. Dry wood may need more than one coat.

7. Danish Oil or Wood Oil Finish

Wood oils are great when you want to enhance the natural grain without building a heavy plastic-looking topcoat.

Use it for:

  • Hardwood gifts

  • Engraved walnut

  • Engraved maple

  • Decorative trays

  • Keepsake boxes

  • Premium wood blanks

Why it works:

  • Brings out the grain

  • Adds warmth and depth

  • Looks more natural than a thick clear coat

  • Great for higher-end handmade gifts

Things to know:

  • Oil finishes need drying time.

  • Some oil-soaked rags can be a fire hazard if not handled correctly.

  • Always follow the disposal instructions on the product label.

Beginner tip: Oil finishes can make engraving look richer, but they can also darken the wood. Test first.

8. Cast Iron Oil

For engraved cast iron, we like to clean the piece first, engrave it, then oil it afterward.

Use it for:

  • Mini cast iron skillets

  • Burger presses

  • Bacon presses

  • Cast iron pans

  • Decorative cast iron gifts

Basic process:

  • Clean the cast iron before engraving.

  • Laser engrave the design.

  • Wipe the engraved area clean.

  • Apply a light coat of oil.

  • Rub it in well.

Good options to look for:

  • Cast iron seasoning oil

  • Food-grade mineral oil

  • Grapeseed oil

  • Cast iron conditioner

Beginner tip: Oil helps the engraved area look finished and cared for, especially after the laser removes the dark coating.

9. Hydrogen Peroxide or LA’s Totally Awesome

Hydrogen peroxide and LA’s Totally Awesome are two simple cleanup helpers we like to keep around for wood projects after engraving.

Use them for:

  • Cleaning smoke residue

  • Lightening scorch marks

  • Wiping engraved wood

  • Cleaning around detailed engravings

  • Freshening up plywood after lasering

How to use them:

  • Put hydrogen peroxide in a labeled spray bottle.

  • Lightly spray the engraved area.

  • Wipe with a soft cloth, magic eraser, or shop towel.

  • Let the piece dry completely before finishing.

  • For tougher residue, test LA’s Totally Awesome on scrap first before using it on your final project.

Beginner tip: Do not soak thin plywood. A light mist is usually enough. And always test cleaners on scrap, especially if the wood is painted, stained, or sealed.

10. Magic Erasers and Cleaning Cloths

Magic erasers are helpful for cleaning smoke marks and residue from some laser projects.

Use them for:

  • Light scorch cleanup

  • Painted blanks

  • Plywood ornaments

  • Wood signs

  • Tile tests

  • Acrylic smudges, when appropriate

Beginner tip: Test first. Magic erasers are mildly abrasive and can dull paint, stain, or shiny surfaces if you scrub too hard.

11. Sanding Blocks

Sanding blocks are a must-have for laser beginners.

Use them for:

  • Smoothing cut edges

  • Removing tabs or rough spots

  • Cleaning light scorch

  • Prepping wood before finishing

  • Sanding between coats

  • Softening sharp corners

Good grits to keep nearby:

  • 120 grit for rough cleanup

  • 180 grit for general sanding

  • 220 grit for finish sanding

  • 320 grit for sanding between finish coats

Beginner tip: Sand with the grain when possible. If you sand across the grain, scratches can show after you add finish.

12. Tack Cloth or Microfiber Cloth

Before spraying a finish, get the dust off your project.

Use it for:

  • Wiping after sanding

  • Prepping before spray finish

  • Cleaning before lacquer

  • Removing fine dust from engraved pieces

Why it matters:

  • Dust can get trapped in clear coat.

  • Dust makes finishes feel gritty.

  • A clean surface gives a more professional result.

Beginner tip: After sanding, wipe the project before spraying. This tiny step makes a big difference.

13. Krylon Short Cuts in Chrome for Glass Engraving

This is a fun little trick for laser engraving clear glass, especially with a diode laser machines.

Use it for:

  • Glass ornaments

  • Glass signs

  • Clear glass panels

Basic idea:

  • Spray the top/front side of the glass with Krylon Short Cuts in Chrome.

  • Let it dry completely.

  • Laser engrave through the dried chrome coating.

  • Wipe off the extra chrome spray with acetone.

  • The glass will etch cleanly.

Why beginners like it:

  • It helps the laser mark clear glass.

  • It can engrave small details clearly.

  • It is great for decorative glass projects.

Beginner tip: Always test your settings. Glass, coating thickness, dry time, and laser type can change the result.  When using a CO2 laser, we spray with a little  dishsoap or LA Awesome cleaner before engraving to to absorb excess heat, which prevents the glass from cracking or chipping.

Safety note: Use acetone in a well-ventilated area, keep it away from flames or sparks, and do not pour it into or use it inside the laser.

14. Denatured Alcohol, Acetone, and Q-Tips

A few small cleaning supplies make laser life so much easier, especially when you are cleaning lenses, mirrors, glass projects, or small detailed areas.

In our shop, we keep denatured alcohol in little nail polish remover pump bottles and use Q-tips for cleaning laser lenses. The pump bottle keeps the alcohol easy to control without leaving an open bottle sitting around on the work table.

Use this setup for:

  • Cleaning laser lenses

  • Cleaning small laser parts

  • Dampening Q-tips without spilling alcohol

  • Keeping denatured alcohol handy but controlled

  • Small cleanup jobs where a big bottle would be annoying

For glass projects, acetone can also be helpful when removing extra Krylon Short Cuts in Chrome after engraving.

Use acetone for:

  • Wiping extra chrome spray off engraved glass

  • Cleaning certain paint or coating residue

  • Small cleanup jobs on glass or compatible surfaces

Important safety note: Label every bottle clearly. Do not assume you will remember what is in the bottle later, because future you is tired and probably holding a half-finished project.

Also, keep denatured alcohol and acetone away from flames, sparks, heat, and the laser. Use them in a well-ventilated area, and do not use them inside the laser while the machine is running.

15. Chalk Pencils

Chalk pencils are great for temporary marking and alignment.

Use them for:

  • Marking center points

  • Lining up handles

  • Marking cast iron

  • Marking dark blanks

  • Temporary layout marks

  • Positioning odd-shaped items

Why we like them:

  • Easy to see

  • Wipes off many surfaces

  • Less permanent than pencil or marker

  • Helpful for class projects and production work

Beginner tip: Keep white chalk pencils near the laser. They show up well on dark wood, cast iron, slate, and painted blanks.

16. Circle Finder Rulers and Center Finder Tools

A circle finder ruler helps you find the center of round objects quickly.

Use it for:

  • Round ornaments

  • Coasters

  • Cutting boards

  • Door hangers

  • Round signs

  • Mini skillets

  • Lids and discs

Why it helps:

  • Faster setup

  • Cleaner alignment

  • Less guessing

  • Better-looking finished projects

Beginner tip: Centering matters more than most beginners realize. A beautiful engraving can still look wrong if it is slightly off-center.

17. Acrylic for Making Jigs

Acrylic is great for making reusable jigs and templates for laser projects.

Use it for:

  • Ornament jigs

  • Pen jigs

  • Keychain jigs

  • Coaster jigs

  • Leather patch jigs

  • Repeat production layouts

  • Class project setup

Why jigs are helpful:

  • They save time.

  • They keep items lined up.

  • They make repeat projects easier.

  • They help students place items correctly.

  • They reduce mistakes.

Beginner tip: Once you get a project lined up perfectly, make a jig. Your future self will thank you.

18. CA Glue for Laser Projects

CA glue, also called super glue or instant glue, is one of those little shop supplies that can save a project, a jig, a layered sign, or your last shred of patience.

We like medium-thick CA glue, especially brands like Starbond or Titebond, because it gives you a little more control than the super thin watery kind. Thin CA glue loves to run everywhere, including places you did not invite it. Medium-thick CA glue is easier to place, easier to control, and great for small laser projects.

Use it for:

  • Layered laser-cut signs

  • Small wood pieces

  • Ornament repairs

  • Jig assembly

  • Acrylic jigs

  • Tiny detail pieces

  • Quick fixes

  • Attaching small embellishments

  • Holding pieces in place before adding a stronger adhesive

Why we like it:

  • Dries quickly

  • Works on small parts

  • Great for detailed laser-cut projects

  • Helpful when clamps are annoying or impossible

  • Nice for little repairs

  • Saves the day when one tiny piece breaks and everyone is already emotionally fragile

Beginner tip: A little goes a long way. Use tiny dots, not puddles. CA glue can leave cloudy residue on some materials, especially acrylic, so test first and avoid using too much.

Shop note: CA glue is great for fast fixes, but it is not always the best choice for every project. For larger wood signs or pieces that need more working time, regular wood glue may be a better choice.

19. Magnet Tape for Laser-Cut Magnets

Magnet tape is a great little supply to keep around if you make laser-cut magnets, classroom projects, fridge magnets, souvenir pieces, or small wood or acrylic items that need to stick to a magnetic surface.

Use it for:

  • Wood magnets

  • Acrylic magnets

  • Souvenir magnets

  • Teacher gifts

  • Class projects

  • Small signs

  • Lightweight display pieces

  • Product samples

Why we like it:

  • Easy to use

  • Great for batch projects

  • Works well for small lightweight pieces

  • Makes cute little add-on products

  • Gives you an easy way to turn small laser-cut pieces into sellable magnets

Pro Tip: Flatten the Magnet Tape First

Magnet tape usually comes rolled up, which means it wants to curl, fight you, and act like it has its own plans for the day.

Before using it, unroll a long strip and stick the magnetic side to a flat metal surface overnight. This helps relax the curl so the magnet tape is easier to work with later.

In a hurry? Cut your magnet pieces, lay them flat, and put a stack of books on top for about 30 minutes. It will not be quite as good as letting the strip relax overnight, but it helps.

The Less-Frustrating Way to Cut and Peel Magnet Tape

Do not cut a pile of tiny magnet pieces while the paper backing is still fully stuck on.

That is how you end up hunched over the table, picking at the corner of each little piece like a raccoon trying to open a granola bar.

Instead:

  1. Pull the paper backing loose from the end of the magnet tape while it is still in a longer strip.

  2. Peel the backing back a little farther than the size you need.

  3. Cut the magnet tape to size after the backing has already been loosened.

  4. Now you have a little magnet piece that is already easy to peel and ready to attach.

This way, you only have to win the fight with the backing once instead of battling every tiny piece individually.

How We Attach Magnet Tape

For a stronger hold, we like to use the magnet tape’s adhesive plus a little backup from CA glue.

Then:

  1. Cut the magnet tape to the size you need, using the peel-back trick above.

  2. Remove the paper backing.

  3. Add a couple tiny dots of medium-thick CA glue, such as Starbond or Titebond.

  4. Place the magnet tape on the back of your laser-cut piece.

  5. Press it down firmly.

  6. Add two tiny clamps for extra security while the glue sets.

At that point, she is not going anywhere.

This method gives the magnet tape’s adhesive a little backup, which is especially helpful if you are making magnets to sell, gift, or use in a class project.

Beginner tip: Magnet tape is best for lightweight projects. For heavier wood pieces, use stronger magnets or a more heavy-duty adhesive. Always test before selling or gifting, because some magnet tape is stronger than others.

20. Masking Tape or Transfer Tape

Masking tape can help reduce smoke staining and protect some surfaces during engraving or cutting.

Use it for:

  • Plywood

  • Painted blanks

  • Acrylic

  • Draftboard

  • Delicate surfaces

  • Projects with heavy smoke residue

Why it helps:

  • Reduces scorch marks

  • Protects the surface

  • Can make cleanup faster

  • Helps keep small pieces together during cutting

Beginner tip: Make sure the tape is stuck down smoothly. Bubbles or loose edges can affect the laser result.

21. Spray Paint for Color-Fill Effects

Spray paint can be used after engraving or cutting to add color and contrast.

Use it for:

  • Engraved signs

  • Acrylic pieces

  • Wood blanks

  • Layered signs

  • Paint-filled engraved designs

Basic process:

  • Engrave the design.

  • Paint or spray the engraved area.

  • Wipe or sand back the excess, depending on the material.

  • Seal if needed.

Beginner tip: Test before using spray paint on a finished project. Some paints can bleed into raw wood grain unless the surface is sealed first.

22. Paint Pens

Paint pens are handy for small details and quick color-fill projects.

Use them for:

  • Engraved lettering

  • Small signs

  • Ornaments

  • Name tags

  • Acrylic details

  • Class projects

Why beginners like them:

  • Less mess than paint and brushes

  • Easy to control

  • Great for small areas

  • Good for quick personalization

Beginner tip: For raw wood, sealing before paint pen work can help reduce bleeding.

23. CerMark for Stainless Steel and Other Advanced Materials

Cermark is a laser marking spray or paste used to create dark marks on certain hard surfaces, especially metals like stainless steel. It is not the first thing most beginners need, but it is worth knowing about if you want to mark stainless steel tumblers, tools, tags, or other metal items.

Use it for:

  • Stainless steel

  • Metal tags

  • Tumblers

  • Tools

  • Some advanced hard-surface testing

Advanced shop note: Cermark can also be used in more experimental projects, including materials like concrete, but that is more of a “Deb is cool enough to engrave concrete well” situation and probably deserves its own blog post.

Beginner tip: Cermark is more expensive than basic sprays and needs testing, cleanup, and correct laser settings. Start with beginner materials first, then work your way up to the fancy science stuff.

24. Spray Gun Setup for Advanced Finishing

If you are making higher-end work or larger production runs, you may eventually want a spray gun.

Use it for:

  • Furniture-style finishes

  • Larger signs

  • Professional wood projects

  • Batch production

  • Smoother lacquer or polyurethane coats

Why it is useful:

  • More control than rattle cans

  • Better finish quality

  • More cost-effective for larger projects

  • Works well with sanding sealer and lacquer systems

Beginner tip: You do not need a spray gun to start. Rattle cans are fine for many beginner and small shop projects. This is the part where Dad may tell you to stay in your lane, and honestly, he might be right for once.

Quick Beginner Finishing Guide

Use this simple guide when you are not sure where to start:

  • Quick indoor decor: clear spray finish

  • More durable indoor wood: spray polyurethane

  • Outdoor signs: outdoor polyurethane or spar urethane

  • Professional wood finish: sanding sealer plus lacquer

  • Food-safe kitchen boards: cutting board oil or butcher block conditioner

  • Cast iron: clean before engraving, then oil after engraving

  • Glass engraving contrast: spray Krylon Short Cuts in Chrome on the top/front of the glass, let it dry, engrave, then wipe off the extra with acetone

  • Smoke cleanup: hydrogen peroxide, LA’s Totally Awesome, magic eraser, or microfiber cloth

  • Lens cleaning: denatured alcohol, Q-tips, and a labeled pump bottle

  • Better alignment: chalk pencils, circle finder rulers, and acrylic jigs

  • Smoother projects: sanding blocks in multiple grits

  • Assembly: medium-thick CA glue, wood glue, tiny clamps, and magnet tape

  • Advanced metal marking: Cermark for stainless steel, after you are comfortable testing settings

Cleaning and Prep Supplies

Adhesives and Assembly Supplies

Sprays and Finishes

Oils and Food-Safe Finishes

Alignment and Jig-Making Tools

Color and Detail Supplies

Safety Supplies

You do not need every product on day one. Start with a simple clear spray, sanding blocks, hydrogen peroxide or LA’s Totally Awesome, and a few alignment tools. As your projects get nicer, larger, or more expensive, you can move into sanding sealer, lacquer, polyurethane, oils, jigs, glue, magnet tape, Cermark, and fancier finishing methods.

Safety Notes for Laser Students

A finish can make a laser project look amazing, but please do not skip the boring safety stuff. The boring safety stuff is what keeps your cute project from becoming a cautionary tale.

  • Always use sprays and finishes in a well-ventilated area.

  • Do not spray finishes inside your laser.

  • Let paint, oil, glue, and clear coat fully dry or cure before engraving near it again.

  • Read the product label before using any spray, oil, glue, cleaner, or finish.

  • Be careful with oily rags. Some oil finishes can create a fire risk if rags are wadded up and thrown away.

  • Do not use regular clear spray on food-contact surfaces.

  • Store denatured alcohol and acetone in clearly labeled containers.

  • Keep alcohol and acetone away from flames, sparks, heat, and the laser.

  • Use Q-tips and denatured alcohol carefully when cleaning lenses, and follow your laser manufacturer’s lens-cleaning instructions.

  • Do not use acetone or alcohol inside the laser while the machine is running.

  • If using acetone for glass cleanup, use it in a well-ventilated area and keep it away from heat, flames, sparks, and the laser.

  • Use CA glue in a ventilated area and keep it off your skin.

  • Be careful using CA glue on acrylic, since it can sometimes leave cloudy marks or fogging.

  • Do not laser freshly glued pieces until the glue is fully cured and you know the adhesive is safe for your material and process.

  • Use magnet tape for lightweight projects only, and test before selling or gifting. For extra hold, add a couple tiny dots of CA glue and clamp the magnet tape while it sets.

  • Test on scrap before finishing your final project.

  • Humidity can affect spray finishes, especially lacquer.

  • Light coats are better than heavy coats.

  • When in doubt, make a sample board.

Final Thoughts: Start Simple, Then Get Fancy

Laser finishing does not have to be intimidating. You do not have to own every tool, every spray gun, every finish, or every mysterious can on Dad’s shelf.

For most beginners, the first goal is simple:

  • Make the project clean.

  • Make it look finished.

  • Make it appropriate for how it will be used.

  • Do not accidentally make it sticky, smoky, blotchy, or weird.

Start with the basics: sandpaper, a clear spray, hydrogen peroxide or LA’s Totally Awesome, a soft cloth, CA glue, magnet tape, and a few alignment tools. Then, as you get more comfortable, you can start testing sanding sealers, lacquer, polyurethane, oils, jigs, Cermark, and advanced finishing methods.

And if you are tempted to grab the professional spray gun before you know what you are doing?

Just know that somewhere, Dad is probably already saying, “Stay in your lane.”
