Q: I have been commissioned to paint sections of an oak tree
that have been cut about 4” thick. The pieces vary in circumference,
there is a bark layer around the outside of each piece, and the inside
section of the wood has been sanded to a smooth finish. I will be
painting with acrylic and would like to seal the wood before I paint.
What would be a good surface sealant for this project?
A:Lascaux makes a wonderful gesso that will seal and
protect the wood as well as the paint. It is very thick and should
therefore be diluted 10% to 20% with water, and then at least two coats
should be applied evenly. Be sure to allow two to three hours of drying
time for each layer.
