Steri-Grout White 3kg

Bond It Steri-Grout White 3kg is a specially formulated, polymer-modified cement-based floor and wall tile grout designed for both trade professionals and DIY installers. Its powerful built-in fungicide actively inhibits black spot mould growth and reduces dirt pick-up, making it the go-to white grout for wet and sanitary environments.

Why Choose This Product

The Bond It Steri-Grout White 3kg stands out for its mould-resistant formula — essential in the UK’s damp bathroom and kitchen environments where standard grouts quickly discolour. The polymer modification improves flexibility and crack resistance, making it reliable over heated subfloors and areas subject to minor movement. Its wide joint range (2–20 mm) means one product handles most domestic and light commercial tiling jobs, reducing the need to stock multiple grouts. Compliance with EN13888: CG2W gives specifiers and contractors confidence in its performance credentials.
