Subject:
the importance of tests, and how

Bill Tindall, E.Tn.
"Latex" paint tells us how the paint was made (latex polymerization) but offers no clue as to what got polymerized, nor the additional ingredients like the coalescing agents. These components will determine what the latex paint sticks to, or not.

To test adhesion cross hatch through the cured coating with a razor blade, with scratches about 1/8" apart. Apply tape, then pull tape off. If the tiny squares lift, adhesion is poor.
