Paint is designed for surfaces such as drywall, plaster, and wood on the interior or exterior of the home. There are specialty paints for certain surfaces such as metal, fiberglass, PVC, or clad/vinyl windows, etc. Sherwin Williams makes a series of special Vinyl Safe colors and formulas for painting vinyl siding, soffits, etc. We also use DTM products for painting metal handrails, aluminum siding, etc. This is a self-priming Direct to Metal paint.
Stains are used for wood surfaces such as decks, pergolas, and solid wood doors when the customer wants to see the wood and grain. Stains soak into the wood whereas paint covers it up. Beware, paint is not designed to be walked on where stain is. Some contractors and customers paint decks. This is a bad idea since paint is not designed for this application. If you want the look of paint on your concrete or wood walkway, patio, or deck, we use another specialty product called Porch & Floor Enamel, or Tread Plex.
