How thick should I apply Kerakoll Aquastop Nanoflex Waterproof Render? 

We suggest the first coat be about 1-2mm, pressing down to ensure maximum adhesion to the substrate. The second coat should be an even layer about 2-3 mm thick, covering the substrate completely.

How long does it take to set?

Subsequent laying of the coating must take place at least 24 hours after application of the last coat, using an inorganic adhesive from the Biogel® range. when working in low temperatures and with high humidity, the waiting time before laying will be longer. If rain falls on the product before it is fully hardened, check it is ready before applying the next coat/covering.
