Ecorend SP15 Silicone Primer is a ready to use, through coloured primer for use prior to the SR15 Silicone Thin Coat Render topcoat. The product has been developed to be highly vapour permeable and to control the suction of the substrate, thus preventing any substrate grin through, and can be applied by brush, roller or spray.
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.
To avoid dampness and discolouration rendering should be avoided below DPC or within 150mm of ground level. Apply with a paintbrush, lamb’s wool roller or spray depending on the size of the substrate. Ecorend SP15 Silicone Primer can be diluted with up to 2% water depending on the suction of the substrate. Stir properly before use. Specification Clauses relating to these products can be found in NBS Section M20 & M21 rendering. BS 5262 Code of Practice for External Rendering and BS 8000-10 must be followed.
