Sherwin Williams Duration Exterior
Duration Exterior is an acrylic latex paint available in several sheens. Before choosing a color, put peeling paint, failed caulk, damaged surfaces, and primer into the work plan.
Where Sherwin Williams Fits
Good paint cannot make up for weak preparation. We put the cleaning, scraping, repairs, primer, coating, color, and sheen in writing.
Before You Choose
01
Peeling, chalking, damage, and old coatings determine the prep.
02
Sun and moisture affect each painted surface differently.
03
Choose color and sheen after the preparation work is clear.
Wait until we check the siding and trim. You need a clear preparation and repair scope before settling on the coating.
Look for cleaning, scraping, repairs, caulk, primer, product, color, sheen, and coat count in writing.
Price both products against the same preparation, repairs, primer, sheen, and number of coats.
See the scope, product, installation details, and price before work begins.
