Pro Line Grout 2.5kg Mid Grey is a versatile, cement-based grout suitable for both wall and floor installations. It contains advanced anti-mould technology, allowing for use on substrates with limited movement, such as underfloor heating, timber, and concrete. With low permeability, it's ideal for areas exposed to prolonged water, like wet rooms, showers, and swimming pools. Special additives increase water repellence, creating a bead effect. This grout dries to a durable, shrink-resistant, mould-resistant, and water-resistant finish, suitable for both internal and external use. It's perfect for grouting ceramic, porcelain, mosaic, glass, quarry, terracotta, and natural stone tiles. Additionally, it contains 30% recycled materials and is available in various colours.
