Force-fit sealing of cracks in screeds and concrete substrates
Excessive shrinkage during drying and curing, overstressing or impeded temperature expansion of screed or concrete substrates often leads to cracks. In order to restore the load-bearing capacity of such cracked substrates, the cracks must be sealed in a force-fit manner. Here, only products especially suited for this purpose should be used. The 2-comp. quick-curing epoxy resin weber.prim 806 offers the necessary safety for sealing cracks due to its high compressive, flexural and bonding strengths.
Simple & safe to the goal
-
Application
1. The cracks and channels must be filled flush with weber.prim 806.
-
3. After complete curing, the loose excess sand must be removed completely. If necessary, the screed or concrete surfaces can be levelled, e.g. with the floor self-levelling compound weber.plan 813-25 (1 - 25 mm).
-
4. Then a fixing of ceramic coverings can be carried out, e.g. with the multi-use flexible tile adhesive weber.xerm 861.
