Epoxy paint is a two-part coating consisting of a catalyst and a resin. The two components combine to form a durable coating capable of standing up to a large amount of duress. If you paint walls with an epoxy coating, employ a specific preparation strategy based on the type of wall you are working on. Once you have prepared the surface, the application process is relatively uncomplicated.
Things You'll Need
Acrylic latex primer
Nap roller cover
Roller extension pole
2-part epoxy paint
Wooden stir stick
3000 roller cover
Wash the brick or concrete wall, using a pressure washer. Use a mop and bucket if you are working indoors. Allow the walls to dry.
Apply a coat of acrylic latex primer, using a roller stocked with a nap cover and affixed to a rolling pole. Allow the primer to dry for two full hours.
Wash all painting tools with water.
Mix the epoxy resin with the catalyst in a 5-gallon bucket, Stir the contents for five minutes, using a wooden stir stick.
Apply a coat of the epoxy paint, using a roller stocked with a 3000 cover and affixed to a rolling pole. Allow the epoxy to dry and cure for four full hours.
If you plan to paint a metal wall with epoxy paint, use a galvanized metal etching primer in place of an ordinary acrylic bonding primer.
To paint drywall with epoxy paint, you do not need to apply a primer first.
Horizontal concrete surfaces like those found in garages and basements require a muriatic acid wash to promote adhesion before epoxy paint will stick. Never attempt to paint concrete flooring with epoxy in the same manner as you would a wall.
