FAQ
Rendering
Sure, you can render over Wykamol Tanking Slurry, but there are a few key steps and conditions to follow to ensure proper adhesion and durability:
✅ General Guidelines:
-
Cure Time: Allow the tanking slurry to fully cure — usually 24 to 48 hours, depending on temperature and humidity.
-
Keying the Surface: The slurry should have a rough finish or be keyed while still tacky (like scratched or lightly brushed) to help the render grip.
-
Primer/Bonding Agent (if needed): In some cases, especially if the slurry has dried very smooth or glossy, you may need to apply a bonding primer or slurry coat (e.g., sand/cement with SBR) before rendering.
-
Render Type: Use a breathable render system — sand and cement render is often recommended, with the right mix (typically 4:1 or 5:1 sand:cement with waterproofer).
-
Thickness: Start with a scratch coat (8–10 mm), followed by a second top coat.
🔧 Steps Recap:
-
Let the tanking slurry fully cure.
-
Lightly key the surface.
-
Apply primer/slurry coat if needed.
-
Apply scratch coat render.
-
Apply top coat render.
