About Silicone Paint
Silicone Paint is a high performance masonry paint. It can be used for painting over an existing render in order to refresh the facade and create a finish that looks brand new, or it can be painted over our Mineral Render to seal the render in.
Depending on the weather conditions, Silicone Paint should be applied 3-7 days after the Mineral Render has been applied to the substrate. This will ensure that a strong physical and chemical bond forms between the Mineral Render and the masonry paint.
- Composition: silicone resin, acrylic binding agents, mineral fillers and pigments
- Bulk density: approx. 1.57 g/cm³

Application Conditions of Silicone Paint
- Application temperature (air, substrate, materials): from +5°C to +25°C
- Number of coats required: 1
- Drying time: approx. 12 hours at +20°C
- Quantity to be used for single coats: about 150-250 ml/m² (depending on the absorptive capacity, substrate structure and application method)
Applying Silicone Paint
Surface preparation: Before application, the surface of the substrate must be clean and dry. Surfaces that are not intended for painting must be adequately protected.
Product preparation: Check that the Silicone Paint is the requested colour. Mix Silicone Paint thoroughly within its container to ensure an even distribution of colour pigments. When using more than one tin of paint for the same surface, ensure that the batch numbers are matched.
Application: Apply the masonry paint using brushes, rollers or spray equipment. Best practice when using a silicone-based paint is to apply the paint to the substrate in a continuous manner one wall/surface at a time. This will ensure that there are no visible drying lines where sections of paint meet.
When used as a topcoat to our Mineral Render system, the masonry paint should be applied 3-7 days after rendering and at the latest 21 days after rendering, depending on weather conditions. When painting over the top of multi-layer render coats, the last layer must be 7 days old.
Masonry painting works must not be carried out during rain or snow, strong winds or direct sunlight without special shields to limit exposure to weather conditions. Drying times for our Silicone Paint is generally 2-3 hours at a temperature of +20°C and about 65% relative humidity. Subsequent coats of Silicone Paint can be applied after 12 hours.
Drying times may be longer in low temperatures and high relative humidity, e.g. in autumn. If the paint is still wet, falling mist can have the same effects as drizzle and may cause water stains and colour changes.
Paints with intense colours (reflection coefficient Y < 20%) should not be used for large facades; the resulting temperature and UV radiation in these conditions may reduce the durability of paint coats and may cause colour fading.
Wash tools immediately with clean water.
Shelf life: up to 12 months from the date of manufacture. Keep dry and in the original packaging at a temperature of +5°C to +25°C.
Safety Measures for Silicone Paint
Avoid contact with skin. Wear eye protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash with water. Wear suitable protective gloves and clothing.
