K Rend Silicone FT Scratch - 25kg

Silicone FT is a water repellent, cement based and polymer modified self-coloured render, requiring only the addition of water and 10 minutes mixing time. If applied as per manufacturer’s instructions, an attractive, low maintenance textured finish is achieved.
SILICONE FT is specifically designed to incorporate the benefits of silicone water repellents into a cement-based render system.
Silicone adds a high water repellent quality, while allowing water vapour to pass freely through the render; thus the amount of dirt adhering to the surface is greatly reduced, ensuring a freshly rendered appearance for a prolonged period of time. This dry surface also improves the resistance of the finished render to algae growth and the natural phenomenon of lime-bloom.
SILICONE FT may be used over K-Rend Base Coat as part of a two-coat system, each 10 - 12mm thick. It should be applied to a uniform thickness to line and level.
Coverage: 2kg per mm thick per sq metre Required: 20-24kg per square metre appx.
SILICONE FT is also designed as a one-coat finish over block-work. It is applied to a minimum 16mm thick, possibly in two passes, and scraped to produce a uniform texture, thus saving labour and scaffold time.
Coverage: 2kg per mm thick per sq metre Required: 32-34kg per square metre appx.

- To achieve a textured finish, scraping should take place when the render has set but not hardened. The exact timing of this operation will vary according to the weather conditions.
- Scraping should be done in a tight circular motion, and the surface brushed down with a soft brush upon

Angles may be formed using angle and stop beads - stainless steel or PVC. Angles may also be formed using chamfered battens.
