Uses

  • Binder for non-skid surfaces
  • Overlays for bridges
  • commercial flooring
  • Warehouses
  • Food & pharmaceutical processing plants
  • Battery rooms
  • Supermarkets
  • Fire houses
  • Plating rooms

  • Ramps and places where structures move because of stress and temperature

Surface Preparation

Concrete: Concrete surface should be free from oil. grease, loose paint. Concrete surface should be sand blasted or blast tracked. If new concrete it should be acid etched with 25% diluted muriatic acid and rinsed three times with fresh water.

Steel: Steel should be free from rust, oil. grease and loose paint. Steel should be sand blasted to white metal.

Application: Different size aggregates can be used to achieve different types of non-skid surfaces, coarse, medium and fine. Color stone quartz, flint shot sand, sand No-1 and sand No-0, bay salt or aluminum oxide are also avaiible. Overlays can be applied at 1/8", 1/4" or more. There are three basic methods used.

Mortar- To each mixed part of Polyflex - 350 add 4 parts of sand by volume. Mix thoroughly and apply with a trowel at the required thickness of the floor.

Slurry Method- To each mixed part of Polyflex - 350 add 2 parts of sand by volume. Mix thoroughly and apply with a trowel. Allow it to self level. Then broadcast more sand while the epoxy is wet. Let it cure and then sweep up the excess aggregates. You can apply a top coat or finish coat as required.

Broadcast- To achieve a 1/8" thick floor. Apply first coat of mixed Polyflex - 350 at the rate of 50 sq. ft./gal. Broadcast Flint shot sand at the rate of 1 lb./sq. ft. Let it cure. Sweep up the excess sand and repeat the above process again. Then apply the final top coat as required.

ASTMC-881-87- Polyflex - 350 meets ASTMC-881-87, grade-1, class B&C, type III. Poly flex - 350 is also available as grade II, class B&C, type III and grade III, class C&C, type III.
