Two-Part UV Resistant Protective Coating
A tough, fast curing, non-slip, aliphatic polyurethane coating designed for protection of SILCOR® membrane systems in all exposed situations. SILCOR Top Coat 75 is UV resistant - it provides a durable, service foot-trafficable finish to roof and deck areas.
SILCOR Top Coat 75 is used for colour-fast, non-slip exposed areas on plant room and lift motor room roofs, balconies, decks, perimeter turn-ups, penetrations and sill or window flashings.
It may be used to give colour fast protection to all grades of SILCOR waterproof membranes used in exposed external situations.
Surface of SILCOR membrane must be clean and dry.
Mix each component separately with a clean stirrer blade, then combine together in a clean dry container and mix thoroughly with high speed dissolver for 5 minutes prior to application. Mix ratio Resin: Hardener is 5:1 by weight.
Apply in two coats by brush or roller – apply second coat in cross direction to the first to give a uniform finish. For spraying use a single wet-on-wet spray application.
Do not use mixed product once it has become thick and stringy, it should be discarded.
Do NOT add solvent.
