 Instruction for use

An installation of the IMPACTODAN 10 is shown in the following pictures:

  1. Extend
  2. Seal overlap
  3. Vertical overlap
  4. Protect installations
  5. Check
  6. Pour the mortar

 Indications and Important Recommendations

- Before pouring down the mortar, check that the surface is at the same level on all the area, that the junction with the walls is equally covered by IMPACTODAN 10, that pillars are wrapped with it and all elements passing through the support or emerging from it.
- The use of IMPACTODAN 10 is recommended if the support compression layers is irregular.
- The floating mortar must be sufficiently resistant in order not to crack.
- As floating floors have anti-dampness materials, the curing time of the mortar is longer. It is recommended to step on the mortar 15-20 days after having poured it down.
- The doors elements must not perforate the floating mortar.
- With self levelling mortars the IMPACTODAN 10 sheet must stay against the floor perfectly overspread without wrinkles.
- Check the product’s technical sheet on safety.
