RS - Full Silicone render - 1.5mm
What is RS - Silicone Render?
Render Store's (RS) Silicone Render is a premium, ready-to-use silicone-based top coat render featuring advanced self-cleaning "Double Dry" technology. It is highly hydrophobic (water-repellent), elastic, and breathable, offering exceptional protection against dirt, algae, and harsh weather conditions. It is the ideal, low-maintenance finish for External Wall Insulation (EWI) systems.

- How does the "self-cleaning" property work on RS - Silicone Render?
The advanced silicone formula creates a highly hydrophobic surface that repels water. Rainwater beads and rolls off the facade, naturally flushing away dust, dirt, and pollutants, keeping the wall clean for years with minimal maintenance. - Is RS - Silicone Render suitable for EWI systems?
Yes. It is highly recommended for use as a facade render within EWI systems on both EPS (Polystyrene) and mineral wool boards due to its high elasticity and breathability. - Which primer should I use with RS - Silicone Render?
You must use a quartz primer, such as RS-Primer or Ceresit CT 16 Primer. This ensures optimal adhesion to the basecoat layer and provides a consistent base color to prevent the background from showing through the finish.
- Preparation: Ensure the basecoat layer is cured (usually 3-5 days) and primed with a compatible primer like RS-Primer or Ceresit CT 16.
- Mixing: The product is ready-to-use. Simply mix the 25kg tub thoroughly with a low-speed drill before application. Do not add water.
- Application: Apply a thin layer with a stainless steel trowel to match the grain thickness (e.g., 1.5mm layer for 1.5mm grain).
- Texturing: Immediately use a plastic float in circular motions to achieve the desired stone texture.
- Protection: Protect the freshly applied render from rain and intense sunlight until fully dry (approx. 12–48 hours).
- Pro-Tip on Application Speed: Ensure enough applicators are on site to complete an entire elevation "wet-on-wet" without stopping. This prevents visible join lines or "scarring" where sections meet.
- Pro-Tip on Color Consistency: Mix several tubs of the same color and batch number together in a larger container before starting to ensure a perfectly uniform shade across the facade.
- Pro-Tip on Maintenance: The BioProtect formula provides long-term resistance to algae, making it a low-maintenance solution for shaded or humid environments.
