How to Use

Ensure even, clean, solid, free from standing water, dust, oil and loose elements substrate. For any
necessary repairs for the proper preparation of the substrate, select the appropriate repair materials from KRAFT Paints product line.

On absorbent substrates (e.g. concrete, cement, old tiles, etc.) prime with Total Proof Primer Aqua or alternatively with Eco Dur Aqua or Dur, by KRAFT Paints. On non-absorbent substrates (e.g. glossy tiles,
mosaics, asphalt, etc.) prime with the transparent Kraft Epoxy Floor Primer Aqua.

After proper preparation and priming of the substrate, Total Proof FLEX is applied in two layers crosswise by brush, roller, or airless gun.

Immediately after the application the tools must be cleaned with warm water and soap or a detergent solution. Remove as much material as possible from tools before cleaning.
