The material basis of WIDOSIL-WSG 1K is an SMP. Polyester fleece G120 is used as reinforcement, with 2/3 of the waterproofing material being applied on the surface underneath the fleece, and 1/3 on top of the fleece. The reinforcement determines the breaking strength and elongation at break and ensures an even layer thickness. The overlap of reinforcement layers must be at least 5 cm. The overlap to other materials is to be determined for each case separately, but should not be less than 10 cm. This results in a homogeneous and crack-filling seal.

The fire resistance has been classified as “flammable” (class B2). Furthermore, WIDOSIL-WSG 1K is resistant to burning brands and radiant heat according to DIN EN 1187.

WIDOSIL-WSG 1K adheres without priming to many surfaces which are dry (max. 5% dampness), free from grease/oil, loose parts and other materials which may lower the adhesion. Surfaces which need to be primed can be found in our references for priming. You may also seek advice from our application engineers.

Additional coatings may be applied withing 24 hours without any further preparation. After 24 hours, the surface needs to be roughened before a further layer may be applied. Alternatively, areas which may need additional coatings, may be sprinkled with quartz sand while first layer is still wet.

Further details, especially regarding hazard statements, security advices and measures in the event of fire can be found in the safety data sheet under sections 2, 4, 5, 6, 7 and 8.
