With very low VOC emissions (EMICODE EC1 Plus), it's built for professional tilers who need floors and walls back in service fast — grouting is possible after just 2 hours and full service after 24. The white formulation is recommended over grey for light-coloured or translucent natural stone and glass mosaics, where a grey-bodied adhesive could show through.\u003c\/p\u003e\n\n\u003cp\u003eSuitable for interior and exterior use, Keraquick S1 Zero White bonds ceramic and porcelain tiles, mosaics and moisture-stable natural stone to cement-based and calcium sulphate screeds, concrete, plywood overlaid floors, existing unglazed ceramic tiles, renders, gypsum plaster, plasterboard and tilebacker boards, up to 10mm adhesive thickness. It's ideal for rapid renovation of heavily trafficked areas — public buildings, motorway services, supermarkets and airports — as well as swimming pools, industrial plants, bathrooms, kitchens and balconies, and for tiling over water-fed or electric undertile heating systems.\u003c\/p\u003e\n\n\u003cp\u003eThis listing is for the 20kg bag.
