Limitations and Important Notes
The product should be protected against frost and direct light during transportation, storage and application. Application temperature should not be lower than 5℃.
Suitable Substrate Conditions
- A vapor retarder for use up to 100 % RH on scarified, very dense or smooth concrete
- Properly prepared epoxy coatings, ceramic tile, terrazzo and VCT
- Properly prepared sound and stable concrete substrates, both smooth and nonabsorbent as well as absorbent or profiled
- Use on cracked substrates as repair resin
Application
- All surfaces should be structurally sound, dry, solid and stable.
- Clean surface to remove any contaminant bond breaking materials such as sealers, wax, oil and dirt.
- If mechanically polishing surface should be profiled using a grinder or bead blaster.
- After mixing A and B components stir the materials fully.
- Apply the primer evenly to fully cover the surface using a fine-pored foam roller cross-strokes
- Broadcast quartz sand (70-140#) to refusal while primer surface is wet.
- Use as moisture vapor retarder must be installed at a uniform layer thickness of at least 30 mils (0.1 perms). After application immediately at a back roll material (90 degrees to the direction of squeege / trowel coat) using an Nylon Fiber Roller pre-saturated in DP400 solution.
- Allow to dry for 16-24 hours then vacuum loose sand. Apply leveling compound.
