The introduction of implementation :
Seamless (clean room) epoxy flooring
A doctor(Epoxy) seamless flooring which is formed with high quality epoxy resin, hardener and special agents, contains special feature that are dust free, seamless and easy to clean. It is suitable for G.M.P. flooring, warehouse, hospital, electrical factory and so on.

Properties :

Smooth, glossy, seamless, dust free, easy to clean and maintain
Working method:
  • (1) 1m/m primer coating(0.3 kg/m2), top coating(0.8 kg/m2)
  • (2) 3m/m primer coating(0.3 kg/m2), middle coating(1.6 kg/m2), silicon coating(2.0 kg/m2), top coating(0.8 kg/m2)
  • (3) 5m/m primer coating(0.3 kg/m2), middle coating(2.0 kg/m2), silicon coating(10.0 kg/m2), top coating(0.8 kg/m2)

Processing steps :

1.Plain floor treatment：

The surface should be clean off such as existing sealers, curing materials, grease, oil, and dirt.

2.Primer coating and operation：

Attention :
Use the solvent based for the concrete whose moisture content is below 8%; use the water based for the concrete whose moisture content is 8% to 16%.

  • Solvent based:After mixing 2055-50A/2055-50B(the mixing ratio is 2:1) evenly, brush or spread on the floor and leave it until dry before apply second layer.

  • Water based:Stirring water and 3118(hardener)(the mixing ratio is 1:1) evenly then mixing 1010 (the ratio is 1). Brush or spread on the floor and leave it until dry before apply second layer

3.Middle layer and operation

  • Resin floating method : Mixing 1030/2108-W (for winter), 1030/2108(for summer) or 1030/5340 (chemical resistance) evenly with the mixing ratio 2:1. Adding #9 silicon sand in it if needed. Smooth the surface and wait until dry before apply top coating.

  • Resin mortar method : Mixing 1010/2108 evenly with the mixing ratio 2:1. Adding 3~5 times #9 silicon sand in ti. Smooth the surfaces and wait until dry before apply top coating.

4.Top coating resin and operation：

  • Putty : If the surface is uneven, use 1351A/1351B(the mixing ratio 1:1) to create an even surface.

  • Top coating operating : Trowel epoxy resin(color can be changed) and hardener by the ratio 3:1 or 5:1; then wait until fully cured (3 days).

5.Other attentions：
  • The ground surface must be hard, smooth and non-peeling.
  • Store product in unopened container in a cool dry location.
  • Use the circle bucket to mix the materials.
  • 1351A/B is used to fill holes.
  • Apply on the wall first.
  • Wait one week for every layer to cure fully.
  • Use up the product within the suggested time.
  • Remove bubbles with brush.
  • Remove dust.
