Nexus ProJoint Porcelain Primer 20kg
Nexus ProJoint Porcelain Primer is a high-performance priming slurry designed specifically for laying porcelain paving on a traditional sand and cement mortar bed. It ensures a strong bond between the porcelain slab and bedding layer, helping to prevent movement and long-term failure.
Formulated with ultra-high polymer and fibre modification, this flexible primer offers excellent adhesion and easy workability. Applied in a single coat to the underside of the paving, it promotes adhesion and controls suction on difficult, low-porosity surfaces such as porcelain, concrete, ceramic tiles, paving slabs, and setts.
Supplied as a powdered primer in two 10kg bags, the tub doubles as a convenient mixing vessel—simply add water and mix. Suitable for brush or roller application, it can be used in low temperatures and is ideal for both internal and external projects. For best results, we recommend using this primer prior to laying porcelain paving and finishing with Rapidflow Porcelain Grout.
