About this product
254 Platinum is the multipurpose thin-set from LATICRETE. This page uses a distributor-hosted copy of its data sheet, which separates the 2 hour pot life in the bucket from the 40 minute open time once it is on the substrate.
Using this specific product
LATICRETE 254 Platinum is listed here as the Multipurpose thin-set version for thin set, tile mortar, and large format tile. 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 Multipurpose thin-set; related versions can use different timing.
- For thin set, tile mortar, and large format tile, pay particular attention to joint depth, water ratio, cleanup and room conditions.
- The source gives no conditions for this time. At 70°F (21°C).
How to check readiness
Inspect shaded joints and verify the stated water or traffic milestone. The data sheet gives 40 minutes of open time. The data sheet gives a minimum of 24 hours of curing before grouting. 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.
