Suitable Substrate Conditions

  • Existing flooring that is structurally sound, solid, thoroughly clean and free of polishes, waxes, grease, asphalt and any other contaminants that might act as a bond breaker.
  • Can be applied over properly prepared and installed 100% solids epoxy moisture barriers and PU vapor retarders.
  • Epoxy cement terrazzo and poured epoxy or PU flooring with the use of the proper Cemimax prime.
  • Dimensionally stable exterior grade-grade plywood.
  • Over Radiant Heat systems
  • Existing surfaces in need of refurbishment, such as well bonded, non-water soluble adhesive residues including cutback.

Substrate Preparation

  • Following all standards, regulations, notices, and installation instructions are applicable and highly recommended.
  • Concrete should be tested for moisture vapor emissions rate and/ or determine relative humidity in concrete floor slabs using in situ probes in accordance with ASTM F1869-11 and ASTM F2170-11.
  • Protect freshly applied leveling compounds from drafts, direct sunlight, and direct source of heat.
  • ASTM F710-11 “Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring.”
  • The substrate must be sound, free from cracks, dry, clean and free from materials which would impair adhesion. Test the substrate according to applicable standards and report any deficiencies. Brush, abrade, grind or shot-blast any weak surface sections or areas which will not accept adhesion. Thoroughly vacuum to remove loose material and dust. Select a suitable primer provided by Cemimax according to surface type and conditions or seek technical assistance. If moisture is detected after proper testing is done select a suitable Cemimax Moisture Vapor Retarder (MVR) before application of leveling.
  • Allow proper primer for applicable substrate to dry thoroughly.


***Notice*** - Some adhesives contain asbestos and some concrete compounds contain natural occurring silica which sanding could cause an unsafe environment when sanding. Extra precautions should be taken when sanding to follow safe working conditions as outlined by OSHA


  • Place 5 liters/ 5.28 quarts of cold clean water into a clean container. Sprinkle in the sack contents (50 lb.) whilst stirring briskly with a drill fitted with football/ oval style paddle mixer and mix to a thick viscous fluid. Lump-free consistency. Do not overwater.
  • Pour the mixture on the area to be applied, spread the material uniformly. If required thickness is needed achieve by using appropriate toothed rake or conventional gauge rake. Remove entranced air by using the spiked roller.
  • Drying time at 65℉ is approx. 14-16 hours. If needed abrade using 40-60 grit sand paper. It improves both the surface quality and the absorbency. Poor air-flow and lower temperatures will significantly affect drying times.
