Preparing a concrete floor for epoxy coatings

Here are the rules for applying real industrial grade epoxy floor coatings on concrete floors:

  1. You MUST prepare the floor by either acid etching, shot blasting or grinding.
  2. The prepared floor MUST have a profile equal to 80-100 grit sandpaper.
  3. You SHOULD use a primer (roll the dice on even coverage without it).
  4. You DO NOT have to top coat your second coat.
Why use a primer?

  1. Primer seals the surface allowing topcoat to flow evenly
  2. Primer maximizes topcoat hide
  3. Primer increases topcoat coverage and adhesion
  4. Primer promotes an even sheen and uniform appearance
  5. Primer seals problems, stopping them from coming up
These rules are repeated for good reason, no one wants to follow them!!
