Ecorend SR15 Silicone Thin Coat Render, is a ready to use, through coloured, flexible thin coat render. Developed using high-performance silicone technology ensures that the finish is highly water repellent, highly vapour permeable and extremely flexible, giving the very best resistance to cracking. This product can be applied by hand or spray and must be used as the topcoat in the SR15 system.

PREPARATION

All surfaces must be sound, clean, dry and free of any material which may impair adhesion. Do not apply to shiny surfaces. Scaffolding must be independently tied to allow for uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified. Mask around the areas where material is to be applied. Masking tape must be removed before the material has dried out. Beads and expansion joints should be included as required by the substrate and BS
standards and carried through all applied materials.

PRIMING

Prime substrate using ecorend SP15 Silicone Primer.

MIXING

Ecorend SR15 Silicone Thin Coat Render is supplied ready to use but can be modified for use depending on substrate and weather conditions by adding max. 2% of fresh water. Always ensure that the material has been mixed using a drill with suitable whisk prior to application.

APPLICATION

To maintain colour consistency, panels should be completed in sequence around the building, and where possible, in the same batch numbers. To avoid dampness and discolouration, rendering should be avoided below DPC, or within 150mm of ground level. To apply the material, use a stainless steel trowel, or suitable spray equipment depending on the grain size. Use the size of the aggregate to gauge the thickness of the render when applying to the substrate ie: ecorend SR15 = thickness 1.5mm. Once the render is applied finish with a plastic float working the material in small circular motions, this will create a natural random surface. Specification Clauses relating to this product can be found in NBS Section M20 & M21 Rendering. BS 5262 Code of Practice for External Rendering and BS 8000-10 must be followed.
