First, tape the inside edges of the cork board
with blue painter’s tape. When you paint and prime the frame of your cork board, the tape will act as a barrier between the frame and the actual cork itself. Therefore, the chance of paint and primer seeping onto the board will be significantly less.
With a 2” dense foam stencil roller, apply two coats of primer to the frame of the cork board. Make sure you prime the sides of the frame too! Don’t be afraid to rotate the cork board to make reaching each side easier.
