Fosroc Nitotile Grout, 20KG, Cement Tile Grout for Filling Joints with Consistent Colour Finish - Sand Stone

Its formulation emphasizes strong bonding, durability, and mildew resistance, which helps it perform in damp environments like showers, countertops, and wet rooms. It also features a dust-free mix for easier handling and application in humid spaces.

The product is sold in a 20 kg flex-pack bag. It’s a cementitious, sanded grout blended with polymers to ensure a durable, strong grout joint with good water resistance and longevity in tile installations.

It is compatible with ceramic tiles and natural stone surfaces. It’s suitable for interior and exterior tiling in residential or commercial projects where a sanded grout is appropriate.

Add clean water gradually to the 20 kg bag until you achieve a smooth, lump-free paste with a peanut-butter-like consistency. Use a drill mixer for uniform mixing, let the mix slake briefly, then remix. Press the grout into joints with a rubber float at a diagonal angle, sweep off excess grout, and clean tile surfaces with a damp sponge before it hardens.

Nitotile Grout-Sand is fast-drying, with initial set occurring within a few hours in typical conditions. Full curing times vary with temperature and humidity, so avoid exposing the grout to heavy traffic until it has adequately cured as per environmental conditions.

After grouting, remove excess material promptly and clean tile surfaces with a damp sponge to avoid haze. Tools can be cleaned with water. If haze remains after initial cleaning, follow up with a gentle cleaning method once the grout is firm.

Sealing is optional but recommended for added stain resistance and easier maintenance. If you choose to seal, wait at least 72 hours after installation to allow the grout to cure before applying a penetrating grout sealer suitable for cementitious grouts.

Sanded grout like Nitotile Grout-Sand is typically used for joints 2 mm to 6 mm wide. For most floor and wall tiling, a joint width of 2–4 mm is common; larger format tiles may use up to 5–6 mm depending on tile size and substrate movement considerations.
