Question 1

What is the drying time for Bostik Cementone Rapid Setting Cement?

Accepted Answer

Bostik Cementone Rapid Setting Cement typically sets within just 20 minutes under optimal conditions, making it ideal for quick repairs and urgent projects. While it hardens quickly, it’s important to allow at least 24 hours for full curing before subjecting it to heavy loads or stress.

Question 2

How to use Bostik Cementone Rendering Repair Mortar?

Accepted Answer

Bostik Cementone Rendering Repair Mortar is ideal for restoring damaged external render, providing a durable, weather-resistant finish. Follow these steps for the best results:

Surface Preparation: Ensure the area is clean, dry, and free of loose material. Lightly dampen porous surfaces to improve adhesion.
Mixing: Combine the mortar with water according to the manufacturer’s instructions until smooth and lump-free. Let it rest for a few minutes before use.
Application: Using a trowel, apply the mortar in layers no thicker than 15mm. Press firmly and smooth out to blend with existing render.
Curing: Allow each layer to cure for 2 to 3 days. Protect from harsh weather conditions like direct sun or rain during curing.
Additional Layers: Apply subsequent layers once the previous layer is fully cured, following the same thickness limits.
Finishing: Smooth or texture the final layer as desired once cured, to match surrounding surfaces.
Clean Tools: Wash tools promptly with water before the mortar sets.

By following these simple steps, you’ll achieve a professional, long-lasting repair. Always check product guidelines for specific instructions.
