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

  • Pressure washer
  • Mop
  • Bucket
  • Acrylic latex primer
  • 5-gallon bucket
  • Nap roller cover
  • Roller frame
  • 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.

Tips & Warnings

  • 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.
