About this product

A sanded grout with a mix step most grouts skip, a 15 minute stand, then cleaning 30 to 40 minutes after application, heavy foot traffic at 8 to 12 hours and a 3 day damp cure.

Using this specific product

Bostik Hydroment Ceramic Tile Grout Sanded is listed here as the Sanded cementitious grout version for sanded grouting. For grouting tile, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Sanded cementitious grout; related versions can use different timing.
  • For sanded grouting, pay particular attention to joint depth, water ratio, cleanup and room conditions.
  • Allow the mix to stand 15 minutes first. Tile adhesive times assume the stated temperature on an absorbent substrate. Dense tiles, damp or cold rooms and thick beds lengthen them. Follow the current data sheet. The source gives no conditions for this time.

How to check readiness

Inspect shaded joints and verify the stated water or traffic milestone. The sheet gives cleaning 30 to 40 minutes after application. Open the area gradually and keep heavy or hot tires off until the full stated milestone. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

Color change alone does not prove the joint is ready for immersion.
