For wood pieces, we recommend sanding to remove any residue or charring that naturally occurs due to laser cutting.
You may want to apply a beeswax to your wood pieces to give them a nice lustre and polished effect. We swear by the brand Howard Feed-N-Wax, but you can use a similar product.
You can also apply a varnish or stain to our Baltic birch plywood before you apply the wax to your design.
Wax makes the grain stand out and shine, it is really quite beautiful! The below sample shows the top unfinished and the bottom with the beeswax. It also smells of lovely orange oil.
