Polythane 500

Polythane 500

Polythane - 500 is an elastomeric polyurethane coating system. Polythane -500 is a 100% solid non-moca polyurethane system. It's low viscosity and self leveling properties make it a unique coating which has excellent bond to concrete, wood & steel. Low temperature curing at 40°F. and up.

Uses

  • Concrete, Wood and Steel Decks
  • Mechanical Equipment Rooms
  • Pool Decks
  • Bridge Decks, Parking Decks and Ramps
  • Balconies
  • Gymnasium Floors

Surface Preparation

All areas must be free of dirt, dust, grease, oil and loose paint. All areas should be dry otherwise a moisture insensitive 100% solid epoxy primer (Polykrete - 200 or PolyBond - 350) should be applied

CONCRETE
Old concrete surfaces should be blast tracked or sanded to remove loose and weak concrete or other contaminants. New concrete should be acid etched with 10% hydrochloric acid and washed thoroughly with water. Surface should be dry.

STEEL
Steel should be sand blasted to white metal.

WOOD
Wood surface should be sound, clean and dry.

APPLICATION
Polythane - 500 can be applied directly to the properly prepared substrate. However, in the presence of moisture, PolyKrete - 200 or PolyBond - 350 can be applied as a primer.

For 1/4" thick flooring system:

  • Apply primer coat with PolyKrete - 200 and broadcast sand while surface is still wet
  • Apply first coat of Polythane - 500
  • Apply second coat of Polythane - 500 and broadcast sand onto the still wet surface
  • Apply a 1/8" thick layer of epoxy mortar of PolyKrete - 200 with sand
  • Top coat with epoxy (PolyCoat) or polyurethane (Polythane)

Advantages

  • 100% Solids, self leveling
  • Needs no primer or 100% solid epoxy primer
  • Can be applied in multiple coats to achieve certain thicknesses
  • Epoxy mortars are applied right on Polythane - 500 where it acts as a waterproofing membrane
  • High wear resistance·High strength·High elasticity
  • Resistance to thermal and mechanical movement
  • Chemical resistance to acids, alkalines, solvents, oils, gas, detergents, salts and animal refuse
