Using this specific product

LATICRETE READY-TO-USE Pre-Mixed Grout is listed here as the Premixed (DS-27-1026) version for grout, tile, and shower. 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 Premixed (DS-27-1026); related versions can use different timing.
  • For grout, tile, and shower, pay particular attention to joint depth, water ratio, cleanup and room conditions.
  • At 70°F (21°C) and 50% relative humidity.

How to check readiness

Inspect shaded joints and verify the stated water or traffic milestone. Tack-free time is 5 hours. Try a protected edge first and avoid turning, dragging or concentrated loads. Open the area gradually and keep heavy or hot tires off until the full stated milestone.

Avoid this mistake

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