180- to 320-grit sandpaper. The higher the numbered grade of sandpaper, the finer the grit is. Use a coarser sandpaper if the wooden surface requires heavier sanding to prepare it for burning and work your way up through a progression of finer grades to give a smooth finish.

If you are buying readymade craft blanks to burn on, chances are that you will require little to no effort to prepare the surface beforehand. These items are usually finished to a very high standard with smooth surfaces and may be suitable for immediate use. Sheets of birch plywood can also sometimes be ready to work on directly “off the shelf” if they have been made to a high quality.

Most wooden surfaces are best prepared for the application of a pyrography design by being rubbed down with a 180- to 320-grit sandpaper. If you wish, you can use water to slightly dampen the surface between sanding; this allows the grain to raise slightly before the next sanding session and results in a smoother finish. Wet the wood with a damp cloth or similar, allow it to dry, and then sand it again. Repeat this process as many times as you feel necessary to get the required smoothness.

If you are attempting to add a pyrography design to an item that has already been varnished, lacquered, or treated in some way, you will need to remove the finish that has been applied before working on it. Trying to burn through varnishes can create harmful fumes that irritate or damage your respiratory system, as well as generally creating marks that are dirty or messy rather than clean and crisp. Working on items like this may require a more vigorous period of preparation before they can be burned on, such as use of coarser sandpaper or an electric sander.
