Before you apply encapsulants to a surface, you must test the paint layers to make sure it will stick. This testing is a requirement and is explained in the training. You must write down the test results on the form in the training booklet. If the paint is peeling from the wall, or not sticking, the paint is probably not strong enough to hold the encapsulant, and you need to find a different method of deleading.
