General
Plan on 1 - 2 days for preparatory work including repairs and washing
the surface. Allow at least one day for the surface to
dry.
Repainting Previously Painted Surfaces
After sanding the desired surface, use primer before top coating.
If you suspect the old glossy surface to be an alkyd paint
and you would like to apply a new latex topcoat, apply a coat
of latex primer after washing and before applying a top coat
of Latex Paint.
Preparing Unpainted Surfaces
Bare Wood:
Exterior Latex Paints are 100% acrylic, allowing harmonious expansion
and contraction of the paint film with the surface substrate
during temperature extremes. Pure acrylic Latex Paints also
allow humidity from inside the house to escape through the
wood and through the paint film without causing the paint to
peel.
Pre-finished Aluminum:
If pre-finished aluminum is glossy, lightly sand then apply a
coat of Acrylic Latex Primer before applying the topcoat, to
ensure lasting adhesion.
Vinyl Siding:
Never use a color darker than the vinyl, to prevent warping from
the sun's heat.
Bare Masonry: (Stucco, brick, concrete block,
cement)
New masonry is very alkaline, and is best not painted for a year,
after which a pure acrylic primer is recommended, followed by
pure acrylic Exterior Paint. If you must paint sooner, wait at
least 30 days. |
