Prime all bare wood with 100 % Acrylic Latex primer. Latex-acrylic based, primer paint is like a thin layer of rubbery plastic that seals the outer surfaces of your home. Primer is used as a base coat because of its epoxy-bonding agents which are designed to stick like glue. This allows the finish coat to go on more evenly and provides a thicker, more protective outer surface. Caulk around ALL windows and doors, siding / trim interfaces, and any cracks. Protect areas not being painted from overspray or paint splatter. Cover entire windows with plastic to protect the screens and windows from over spray. Apply siding paint using a spray application, adding a back roll where applicable. Apply trim paint using a brush and roller application. All material is applied at manufactures specifications.
