ECO Prim Grip (+ Thinset) vs Thinset adhesion/grip test. Both were applied to a sprayed epoxy flooring over concrete.
This epoxy flooring is 30 years old and super tough. But we want to tile over it.
Part 1 of the test was an adhesion test without scuffing the floor first.
Part 2 I scuffed the floor with 40 grit first then applied the ECO Prim Grip or Thinset.
Part 3 I scraped what remained of the mixtures from Part 2 from the floor to see which had adhered best.
