K Rend Silicone TC is a pre-mixed, silicone based, ready to use organic resin render which is usually hand applied. It provides a low maintenance, decorative finish and is available in a wide range of colours. K Rend Silicone TC is a decorative textured finish for external wall systems. Some key features include; Water Repellent, Excellent adhesion to substrate, Natural finish, Weather resistance, Easy to apply, Allows substrate to breathe and High flexibility.
Preparation of K-Rend Silicone TC15 Topcoat
- A test panel to check colour and final appearance is recommended
- Backgrounds should be clean, level, dry and free from efflorescence
- Mask all adjacent surfaces including windows, sills, doors, timber, glass, brick & flooring
- Protect weather exposed surfaces
Application of K-Rend Silicone TC15 Topcoat
- The temperature of the substrate and surrounding air should be a minimum of 5oC
- Do not apply in conditions of strong sunshine or wind; do not apply onto damp or frozen substrates
- Allow freshly applied render basecoats a minimum of 14 days before work commences
- Prime walls using Primer TC colour co-ordinated to topcoat and allow 24 hours drying time for primer before applying topcoat
- Stir bucket contents thoroughly using a slow speed mixer. A small amount of water can be mixed with the product to achieve the best working consistency
- Apply the product to the thickness of the largest grain size using a stainless steel float; allow to take up slightly.The surface is then rubbed up in a circular motion using a plastic float to create the texture
- Complete continuous surfaces without interruption, working to a wet edge at all times
- Drying times may be prolonged by lower temperatures and/or high humidity
- The fresh render must be protected from rain and from drying too fast
Coverage:
Silicone TC 10 – largest grain 1.0mm; coverage = approximately 1.8 kg / m2
Silicone TC 15 – largest grain 1.5mm; coverage = approximately 2.5 kg / m2
Silicone TC 30 – largest grain 3.0mm; coverage = approximately 5.0 kg / m2
These figures depend on substrate and application technique.
