Chemical Resistance: Tests are performed according the ASTM D543 – Practice A (Immersion test for 7 days at 77°F/25°C). The fully cured product is resistant to:

  • Water (Distilled, Tap, chlorinated, sewage, sea)
  • Sulfuric acid 50%wt
  • Citric Acid, 30% wt
  • Caustic Soda, 50%
  • Hydrochloric Acid, 15%
  • Diesel
  • Hydraulic Oil
  • Diesel Engine Oil


Refer to manufacturer for resistance of other reagents.


Limitations: Application at ambient temperature below approximately 41°F (5°C) is not recommended. Exposure to temperatures exceeding 149°F (65°C) for prolonged periods is not recommended. Substrate temperature must not be lower than 41°F (5°C) during installation and during the full 3 to 5-day cure of the floor


Surface Preparation:


Concrete Substrate: Surface of application should be clean and sound.  The surface must be free of any dust, oil, grease, laitance, curing compounds or any other contaminants. New concrete substrate should be 28 days old and must be a minimum of 3625 Psi (25 N/mm2) compressive strength concrete.  Chlorinated rubber, wax or resin based curing compounds must not be used.  CHEM-FLOOR S should not be applied on surfaces that have been sealed with a permanent type of form oil, releasing agents, etc.  Remove these substances before application of CHEM-FLOOR S.  The surface temperature shouldn’t be below 41°F (5°C).


Acid Etching: On new concrete surfaces, remove laitance and un-bonded cement particles by acid etching.  Dampen the surface with tap water.  Use Chem-Crete’s CONCLEAN CCC070 or dilutes Muriatic acid to a 10% solution.  Always add the acid to the water.  Scrub the acid water solution onto the surface at the rate of 50 ft2 / Gal (1.22 m2 / liter).  Allow the solution to sit for 20 minutes or until the acid bubbling stops.  Scrub and flush thoroughly with clean water until all traces of acidity are washed-off from the surfaces.  Remove water by squeegee, vacuum or broom and allow the surface to air dry. Other methods may be adopted if the acid etching method is not feasible, such as shot blasting, sand blasting or mechanical grinding.


Product Preparation: Store product at 70°F (21°C) during application and for at least 2 days prior to use. Low temperature will increase the viscosity of the product causing poor coverage and retarded cure.


Mixing:  CHEM-FLOOR S is supplied it two pre-weighed parts resin and hardener. No additions or omissions are required. Stir each part separately. Mix part ‘A’ with part ‘B’ in a clean mixing container.  Mix both parts using slow speed hand drill fitted with a mixing paddle attachment.  Carefully scrape the sides and bottom of the pail during mixing. Blend for 3 minutes until achieving a uniform color and consistency.  Mixed epoxy must be processed within the pot life. Mixed epoxy will cure much faster in hot weather. Large batches of mixed epoxy will cure much faster than small batches.


Application (Non-slip Aggregate Flooring System):

  1. Surfaces that are damp, porous or have a rough concrete finish should be primed with CHEM-FLOOR Clear or CHEM-PRIME at an average coverage of 200 ft2 / Gal (5 m2 / liter). This is equivalent to approximately 0.553 Lb / yard2 (300 grams / m2)
  2. Apply the CHEM-FLOOR S at an average coverage of 100 ft2 / Gal (2.5 m2 / liter) with a squeegee and then back roll with a short napped mohair roller with a solvent resistant core. Let the epoxy level out on the substrate for 5 minutes.
  3. While the epoxy resin coat is still wet, the aggregate or silica sand 0.3-0.8 mm grade is sprinkled onto it by hand or by any suitable broadcasting method at a rate of 1.84 Lb per yard2 (1 kg / m2). Excess of aggregate must be used to facilitate a good coverage of the substrate, otherwise, sparse areas or voids will be formed which will require an additional coat of aggregate. If a wet or glossy appearance on aggregate is evident, it is an indication that insufficient aggregate has been applied.  Use of spiked shoes by the applicator is advised while broadcasting the aggregate.  CHEM-FLOOR S coat with aggregate must be allowed to dry before proceeding with the next step.  Always leave a wet edge of about one-foot without ridges to allow for joining the next course of material.
  4. Remove all loose aggregate of sand by either sweeping or preferably vacuum cleaning. Sand-off any imperfections using a floor sander. Sweep and vacuum debris prior to applying the second broadcast. Apply an additional Base coat and aggregate as described above.
  5. The finish coat of CHEM-FLOOR S is applied to the surface at a rate of 200 ft2 / Gal (5 m2 / liter) with a squeegee. Draw down the finish coat until the desired surface texture is obtainer.


Cleaning: remove uncured CHEM-FLOOR S from tools and equipment with suitable solvents such as Xylene, Toluene or CHEM-CRETE BLENDED SOLVENT immediately after use. Cured material may only be removed mechanically.


The product can be stored for minimum of twelve months at temperature from 50°F to 95°F (10°C to 35°C) in the unopened original packaging.  Protect from direct sunlight.


After hardening thoroughly, CHEM-FLOOR S is physiologically harmless. Keep the resin and hardener away from the eyes mouth and skin.  Do not breathe in the vapors.  The uncured mixture can cause irritation of the skin.  For best protection, wear rubber or plastic gloves.  In case of contamination, wipe away resin or hardener immediately from the skin using paper towels and then wash with soap and water or hand cleaning detergent. Empty resin and hardener cans must be disposed according to local city code or regulations.   Under no circumstances empty cans should be used to store food or drink even if they have been thoroughly cleaned. Follow all cautionary direction as printed on container’s labels.
