Remove all traces of loose existing coating material. SoudaGum Hydro can be used without primer on moist substrates but not in the presence of stagnant water.
Open the lid and stir the product before using.
Apply by roller or brush in 2 layers to a thickness of 2mm (Recommended).
SoudaGum Hydro may be reinforced with a fleece lining such as Soudatextile.
The second layer cannot be applied until the first has dried completely.
After approximately 12 Hours the treated surface should be dry and follow-up work can begin.
Be aware that different environmental factors can influence the drying time.
Connection and expansion joints must be previously properly dimensioned in order to achieve optimal performance. Suitable backing material is essential (foamed polyethylene).
For optimal elastic characteristics of the sealant 2:1 or 1:1 width / depth ratio of the joint is suggested (minimal joint width: 6mm; maximal joint width: 20mm).
Approx 1.4kg/m² (Based on 1mm thickness) to 2kg/m² (Based on 2mm thickness).
This equates to approx 0.5m² - 0.7m² per kg.
