Painters Beware: What is Wax Bleed and Solutions to Fix It.

What happens here

If there's any uncertainty about the primer's adhesion, perform a cross-hatch test. Apply the primer to a small, inconspicuous area and allow it to dry for at least 24 hours. Then, use a sharp knife to make several parallel cuts into the primed surface, followed by several perpendicular cuts, creating a grid or cross-hatch pattern. Apply strong masking tape firmly over the scored area and then quickly peel it off. If paint lifts off with the tape, it indicates poor adhesion, suggesting that even the primer isn't bonding sufficiently to the wax hydrocarbons.

Goal: To confirm proper adhesion of the primer, perform a cross-hatch test after the primer has dried for a day. This involves scoring the primed surface and applying tape to check for paint lifting.

Tools and materials

  • Masking Tape (strong adhesive)
  • Sharp Knife or Utility Blade

What they say

could just come flying right off. So one thing you can do, if you're really unsure, be for painting it, do what we call a cross hatch test. So we're going to put some paint on there, let it dry and then come back the next day. We're going to take and do a cross hatch test. We're going to take a knife, slice the paint, cross hatch it, put some tape over the top of it, peel it off and if it peels the paint right off, then you've got a problem of wax bleed more than likely. So that's what it is,
