Description
ARDEX EG 18 PLUS combines the chemical resistance and hygienic performance of a full epoxy grout with the ease of application of a standard cement-based grout — no special tools required, and it cleans off with water for up to 60 minutes after application.
Classified RG (Reaction Resin Grout) to BS EN 13888 and R2 (Reaction Resin Adhesive) to BS EN 12004, EG 18 PLUS can be used to both grout and fix tiles, making it a genuine two-in-one solution for demanding wet and hygiene-critical environments — swimming pools, showers, bathrooms, commercial kitchens, hospitals and spas.
