Tiled floors and walls in food plants, dairies, labs, industrial kitchens, plant rooms and thermal or salt-water pools need epoxy bedding and grout that resist acids, cleaning agents and wash-down. These are specialist systems.
General guidance based on the manufacturer data sheets. Site conditions differ: confirm the system with MCT before you start. Where we do not name a product, ask us and we will confirm the right one.
Record the chemicals, concentrations, temperatures and cleaning methods. Sikadur-54 Ceramic gives an immersion resistance list, for example 5 % acetic acid, 10 % lactic acid, whey and sea water (Sikadur-54 Ceramic p.2). SikaCeram RSG 705 takes dry heat up to +50 °C, but not chemical and mechanical exposure at the same time. Ask us for its full chemical table (SikaCeram RSG 705 p.2).
