Sanding Your Wood: Before and After You Burn + Prepping Wood Surfaces for Pyrography

Sanding, like it or hate it, is a part of being a wood burning artist. Sanding your wood before and after you burn can make your entire piece and your burn lines crisper.

A smooth wood surface will help you create a smoother, better burn. It is worth the time it takes to make it smooth, trust us.

There are some things you can do to make the job a little easier on yourself. See the steps below to getting the perfect surface to burn on:



Prepare the workspace

Place the wood slice on a flat and stable surface that won't move during sanding. You may want to clamp it down to keep it steady.

SAFETY FIRST!

Make sure you are in a well ventilated space, have an air purifier if sharing the space and you are wearing proper safety equipment. Something to protect your eyes and your lungs. Do it every time. The last thing you want is for your art to cause you harm. Protect yourself!

My favourite mask to use for everything I do with pyrography is RZ Mask. The M model is my favourite but they have so many to choose from and in so many different colors... They all have activated carbon filters which are replaceable and the mesh mask shell and valves are washable and reusable. They are comfortable, breathable and are 99% efficient against particulates down to 0.1 microns in size.

Choose the right sandpaper

The type of sandpaper you use will depend on how rough the surface of the wood slice is. Start with a coarse grit sandpaper (60-80 grit) and gradually move to a finer grit (120-150 grit) for a smoother finish.

Understanding Grit:

In the US grit is determined based on a scale. When shopping for sandpaper, you’ll see numbers such as 80-grit, 100-grit, or 200-grit. Keep in mind:

  • The higher the number, the smaller the grains and the finer the sandpaper grit.

  • The lower numbers indicate larger grains and overall coarser sandpaper

Generally you want to start out with a lower grit (coarser sandpaper). This helps to get rid of any larger scuffs, scratch marks, bumps and/or irregularities. Then you will want to increase the grit and finish off with a finer, more gentle sandpaper to get that ultra smooth finish.

Always sand with the grain of the wood, not against

Sand your pieces before you do any wood burning to ensure clean and crisp lines. A smooth surface will be much easier to burn on, and will create a better result.

Begin sanding the wood slice using the coarse grit sandpaper. Work in the direction of the grain and use a back-and-forth motion. Sand any rough spots until they are smooth.

Once you've sanded the rough spots with the coarse sandpaper, switch to a finer grit sandpaper. Continue sanding until the surface is smooth and free of any scratches.



Finish with the finest grit for the ultimate smoothness

For an extra-smooth finish, use the finest grit sandpaper (220 grit) to sand the surface once more at the end. This will remove any remaining scratches and leave the surface with a smooth texture.



Clean the surface

Wipe off any dust and debris from the wood slice with a clean cloth. You can also use an air compressor to get rid of any dust. Be careful to not get too close to the bark on a live edge wood slice. The strong air may remove delicate bark pieces and can come off. If you don’t have access to an air compressor, use a brush to sweep of the dust or, better yet, use a bristle attachment on a vacuum to safely capture the dust.

In the video below, I used:

RZ Mask: M (RZ Mask rocks!! My first mask was the M2 but the M has the ear straps which fit me better. They have loads of styles and sizes to choose from!!)

Dewalt Oribit Sander

Course Sandpaper: 80-100 grit

Fine Grit Sandpaper: 240 grit

Sanding after you wood burn a piece

Sanding a piece after you burn removes any tracing lines as well as “overburn.” (Overburn, as you can see here on the left) is when you have a browning coloration right next to your burn line on the surface). Sanding your piece after you burn it gives your piece crisper and finer lines.

Use a 200-grit or 220-grit sandpaper (the finer the better) and remember to be super gentle when sanding at this stage, especially if you don’t burn very deep.

If you have any shading or surface burn lines, they may come off, so really; go light and slow here.

Watch how I sand my wood slices before I burn on them!

more Fun tips and tricks

Sanding sponge versus sanding block:

Since sponges form to your hand, a block sand paper will allow you to put in less effort and ensures you are sanding flat and not creating any divots. Try wrapping a sandpaper sheet to a scrap wood if you don’t have a pre-made sanding block (use a tube or pvc pipe instead of a block for contoured wood pieces)


Sanding power tools:

These come in handy! Especially if you prefer to sand your pieces in “batch work” style, meaning you sand a whole bunch all at once. I recommend this, because it is a time saver. You only have to get dirty once, you only have to pull out the tools once, and clean up the mess once. Then you have a stack of ready to go canvases. It’s awesome.
