Preparation and Application

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 discoloration rendering should be avoided below DPC or within 150mm of ground level. Apply with paintbrush, or lamb’s wool roller or spray depending on the size of the substrate. PTP Silicone Park Homes 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 rendering. BS 5262 Code of Practice for External Rendering and BS 8000-10 must be followed.
