How to use Trubuild Cementitious Waterproofing Coating?
- Clean surfaces of dirt or grease first. Fix cracks over 5 mm with fillers and spalls with grout.
- Dampen to SSD state. Blend Part B powder into Part A liquid at a 1:1.4 weight ratio and let it rest for 5-6 minutes.
- Spread two coats at 1.8-2 kg/m² for 1.2-1.5 mm thick. Gap coats by 4-6 hours, sand second for grip, cure 12-24 hours.
- Water cure 24 hours, air dry 3-5 days.
FAQ
Where can Aqualock Flexi be used?
Aqualock Flexi works on concrete roofs, balconies, bathrooms and water tanks as a trusted cementitious waterproofing coating. It suits parking decks, swimming pools, retaining walls and lift pits too. The cementitious water proofing handles hydrostatic pressure on both sides of masonry or concrete.
Is it a flexible coating?
Yes, Trubuild Aqualock Flexi forms a flexible cementitious coating with 150% elongation and crack bridging up to 2 mm. This elastomeric quality in the cementitious waterproofing coating prevents cracks from water leaks during surface movement.
Is it safe for drinking-water tanks?
Trubuild Aqualock Flexi holds CFTRI approval for non-toxicity. This makes cementitious water proofing safe for water tanks and reservoirs. It passes food-grade tests with no leaching issues.
Can it resist UV?
