Where To BuyThe substrate must be well cured, mechanically and dimensionally stable, strong, clean, dry and free from flaking parts, laitance, grease, oil, paint, wax, corrosion deposits, dust, loose materials, etc. It should be ensured that tiles are dry, and free of contaminants that could otherwise impair adhesion. Concrete, screeds, renders, and blockwork should be cured sufficiently that all shrinkage movement has occurred.
Minimum age of the substrate (In mild weather):
- Renders must have cured at least 1 week for each centimeter of thickness.
- FloorPro Rapid Screed (rapid setting cementitious semi- dry screed) must have cured at least 3 days.
- FloorPro Easy Screed (normal cementitious semi-dry screed) must have cured at least 28 days.
Note: The screed drying time is subject to the screed thickness and site conditions.
Priming:
The prepared substrate should be thoroughly soaked, to a saturated but surface dry condition prior to application of the TilePro Fix, few hours ago, before applying the mix to minimize absorption. Any residual surface water should be removed prior to commencement.
Gypsum substrates and anhydrite screeds must be perfectly dry, sufficiently hard and free of dust. It is absolutely essential that very absorbent cement-based substrates, plasterboards, cement boards, calcium silicate boards, aerated concrete and anhydrite screeds are prime with BondPro Penetrating Primer. For tile-on-tile applications, prime the existing tiles with BondPro Grip Primer. Areas subject to high moisture content should be primed with FloorPro Primer MT.
