About this product
A tile adhesive with a long pool rule: walk and joint after 24 hours, fully hardened at 7 days, but no filling a pool for 28 days.
Using this specific product
Schomburg Unifix S3 is listed here as the Rapid tile adhesive (German sheet) version for tile fixing and pool tiling. For bonding parts, 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 Rapid tile adhesive (German sheet); related versions can use different timing.
- For tile fixing and pool tiling, pay particular attention to surface fit, cleanliness, clamping pressure and bond-line thickness.
- Pot life is 45 minutes. Use between 5 and 25°C. The source gives no conditions for this time.
How to check readiness
Test a noncritical offcut or wait for the stated load milestone before stressing the joint. The sheet gives an open time of 30 minutes. Try a protected edge first and avoid turning, dragging or concentrated loads. Test the seam or finish at the least-ventilated spot before normal water exposure.
Avoid this mistake
Handling strength and full load strength are different milestones.
