Silicone TC is an organic resin render incorporating a Silicone resin emulsion and an Acrylic resin dispersion in a ready to use render. If applied according to the manufacturer’s instructions it can be used on a variety of prepared exterior surfaces to provide an attractive, low maintenance textured finish.
Silicone TC is a low odour, ready to use organic resin render which is quick and easy to apply and is available in a wide range of colours. It provides excellent adhesion and application properties and, following appropriate preparation, can be applied to a wide variety of substrates. Silicone TC is a cement-free render with greater flexibility. Although primarily for external application, Silicone TC can be used internally.
SILICONE TC incorporates the benefits of silicone technology to provide a water repellent final surface which gives excellent protection. The silicone allows water vapour to pass freely through the render whilst allowing the finish to remain weather resistant. Silicone TC contains a biocide to help prevent infection from moulds, yeasts and algae and it has a low susceptibility to soiling and contamination.
PREPARATION
- 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
- 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 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
