MD Carpentry Workshop Pro Joint Porcelain Paving Primer 20kg

Pro Joint Porcelain Primer is a high performance priming slurry for porcelain paving. The  Primer is an ultra-high polymer and fiber modified flexible waterproofing primer with excellent work ability and adhesion properties. Applied in one coat for fast application to promote adhesion and control suction on difficult substrates such as Porcelain concrete, ceramic tiles, paving slabs or setts. The powdered primer is supplied in two 10 kg bags to allow the bucket to act as the ideal mixing vessel with the simple addition of water. We recommend that this primer be used prior to using the Pro Joint Porcelain Grout.

To apply, use a masonry brush or roller and brush a thorough and even coat of the primer to the underside of the paving. The working time for the mixed slurry is approximately 60 minutes at 20°C. Depending on temperature and moisture, the primer should cure sufficiently for the paving to be laid in 10 to 15 minutes following application. All tools should be washed out with water immediately after use. Waste material shouldn’t be emptied into drainage systems.
