{"product_id":"solar-reflective-roof-coating-white-fibre-reinforced","title":"Solar Reflective Roof Coating – Fibre Reinforced White Heat-Reflective Topcoat, 5kg \u0026amp; 20kg","description":"\u003cp\u003eBy late July a dark flat roof in full sun can reach surface temperatures far above the air temperature — and everything underneath pays for it. The room below is uncomfortable, and the roof covering itself ages faster: felt softens and blisters, bitumen bleeds, membranes and adhesives work harder through every heat cycle. A brilliant-white solar reflective coating bounces that heat back off the roof instead of letting it soak in.\u003c\/p\u003e\n\n\u003cp\u003eThis is a fibre-reinforced, one-coat white topcoat for existing flat roofs. It goes on cold by brush, roller or squeegee over sound felt, asphalt, concrete, metal or timber, and cures to a tough, flexible, highly reflective white film. The embedded fibres bridge and reinforce as the coating cures, so it copes with the small movements and hairline crazing that come with an ageing roof rather than cracking over them.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHighly solar reflective — keeps the roof surface and the room below measurably cooler in summer sun\u003c\/li\u003e\n\u003cli\u003eProtects the existing covering from UV and heat cycling, extending the life of a sound but tired roof\u003c\/li\u003e\n\u003cli\u003eFibre reinforced, so it resists cracking and splitting as the roof moves\u003c\/li\u003e\n\u003cli\u003eOne-coat, cold-applied, ready to use straight from the tub — no primer, no mixing, no hot works\u003c\/li\u003e\n\u003cli\u003eBonds to felt, asphalt, concrete, metal and timber\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat this is for — and what it isn't\u003c\/h3\u003e\n\u003cp\u003eThink of this as a \u003cstrong\u003eprotective and reflective topcoat for a roof that is already watertight\u003c\/strong\u003e: summer heat management, UV protection, and buying years of extra life out of a sound covering.
