I apply a second coat after the primer is dry.And then a fourth coat.If I can still see the knot, I will apply additional coats.We need to apply coats of primer until we can no longer see the knot.
I sand after the final coat is dry.I will apply another coat of primer if I sand too much.
If I am working on a new project, I will apply three coats of Zinsser BIN Primer to the knots and then apply a coat of latex primer.latex primer won't stop knots from bleeding through the paint.The knots will have a minimum of four coats of primer now that I need to prime the rest of the project.
If I am repairing a knot that bled through the paint on a project that has already been painted, I will not prime the entire piece.The primer we applied to the knot will be a great base for our paint.
The last step is to apply quality paint.We can either use a brush or sprayer.
