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:

1. Cure Time: Allow the tanking slurry to fully cure — usually 24 to 48 hours, depending on temperature and humidity.

2. 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.

3. 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.

4. 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).

5. Thickness: Start with a scratch coat (8–10 mm), followed by a second top coat.

🔧 Steps Recap:

1. Let the tanking slurry fully cure.

2. Lightly key the surface.

3. Apply primer/slurry coat if needed.

4. Apply scratch coat render.

5. Apply top coat render.
