Using this specific product

For installing or finishing a floor, 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 Powder (Spanish-language data sheet); related versions can use different timing.
- For self leveler, underlayment, and tile, pay particular attention to subfloor condition, trowel coverage, room temperature and traffic plan.
- The data sheet does not say what the 2 to 3 hours count from; walkable is stated at 70°F (21°C). Good drying conditions: air at 65 to 75°F (18 to 24°C) and 40 to 60% relative humidity. At 70°F (21°C).
How to check readiness
Test the least-ventilated area before walking, covering or replacing furniture. Tile and stone that are not moisture sensitive can be installed once the underlayment is walkable, about 2 to 3 hours. Finished floor covering can be installed 16 hours after NXT Level is installed. Try a protected edge first and avoid turning, dragging or concentrated loads.
Avoid this mistake
Foot traffic, furniture and rugs can have different return times.
