Retrospective crystalline waterproofing

Key Facts

1 Opening cracks and damaged areas

Remove all loose debris from the cracked and damaged areas. Chisel out the static crack to a width of at least 20 mm and a depth of 25 mm.

2 Immediate waterproofing of water leaks

Seal water leaks professionally with the rapid hardening mineral-based plugging mortar, FIX 20-T.

3 Mixing FIX 20-T

Homogenously mix a quantity of powder appropriate to the water leak with approx. 25% water to a pliable consistency. Form a plug of the right size, by hand. Work quickly – the pot life is only approx. 3 minutes.

4 Plugging the water leak

Press the formed plug into the area where there is running water. Hold the plug tightly in place until it has hardened. Immediately work the plugged area with a trowel.

5 Repairing voids

Make good faulty areas with FIX 20-T or alternatively ASOCRET-IM.

6 Producing the coved fillet

Produce a coved fillet of edge length approx. 4 cm, with ASOCRET-IM and apply into the freshly slurried area with AQUAFIN-IC, wet in wet. After 1 – 3 hours, overcoat the ASOCRET-IM with AQUAFIN-IC.

7 Application of AQUAFIN-IC

Dampen the area to be waterproofed, with clean water. Apply two coats of AQUAFIN-IC at the required consumption rate with a roofers broom, brush or by spray. Apply the second coat, whilst the first coat is still tacky and has not dried out.

8 Post treatment

Protect the fresh coating from weathering such as e.g. sun, wind, rain and frost etc. Keep the waterproofing coat damp for a minimum of 3 days. Carry out the first damping process after approx. 1 day.
