PVC Filler & Repair Paste

Stelmax PVC Filler & Repair Paste is a mix of PVC resins, pigments, plasticiser and solvents, that will gap fill and bond readily to form maintenance free joints of exceptional strength when used to bond and fill rigid and plasticized PVC and PVC coated metal. Good adhesion can also be achieved when used with many porous substrates.

When dry the product will exhibit weathering, UV and chemical resistance similar to that of a good quality rigid PVC. Sealed joints will retain a degree of flexibility to cater for minor expansion and contraction of the substrate whilst remaining water and gas tight. Stelmax PVC Filler & Repair Paste is available in British Standard colours with matching facilities available on request for special colours.

Available in 50gm and 132gm tubes and 300gm cartridges, the product can be supplied in ANY colour. This product is more commonly used in association with coated metal fabrications such as fascias and wall claddings to provide weathertight seals between panels or to be used as a filler to repair any compromise to the weather protection or encapsulation caused by screw fixings, cut edges etc.
