> How can I minimize the appearance of lap marks appear after the paint has dried?

Often caused by wrong termination techniques and/or paint dilution, you may minimize the occurrence of lap marks by using a “W’ or “M” pattern when roller painting. Doing so will help spread the paint and create an even film.


> What can I do about mildew on areas that I want to paint?

Treat mildew growth with disinfectants or a 1:3 solution of laundry bleach to water, respectively. Let stay for twenty-four (24) hours then wash off residue with water. Allow all cleaned surfaces to dry before painting.
