Joint Sealer

This product was developed during 2013 at the request of a mass housing developer constructing panelled houses in the Western Cape. It is used to seal the joint between panels, and the main requirements are good adhesion to the substrate, flexibility and high film build. Essentially, it is a high solids acrylic formulated on a blend of binders to provide the required properties. As with all products of this type, there is a degree of shrinkage on drying, necessitating two "coats" to be spackled into the joint. Since the successful introduction of the product, contractors have used it to fill plaster cracks with equally good results. Its toughness and flexibility would make it a good option to seal between timber panels used to construct timber homes, in addition to the above applications.
