How to use
Method of use
KingProof PV Disc must be installed by experienced and qualified personnel.
Surface preparation
The substrate should be clean, dry and free from grease and bituminous materials. The profile of the substrate should be sound and smooth without projected or sharp objects.
Application
Using a compressed air gun fasten KingProof PV Disc to the clean and sound substrate.
If a backing material is to be used prior to the installation of the waterproofing membrane, KingProof PV Disc should be placed and fastened over the non-woven fabric.
Spot-weld KingProof PVC membrane to KingProof PV Disc using a hot air welding machine. Adjust the temperature of the air welding machine according to the ambient conditions.
Coverage, packaging and storage
Packaging
KingProof PV Disc is available in 10 mm thickness and 80 mm diameter.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
