Specially formulated for Porcelain Paving Projoint Grout has been developed for joint widths of 2-20mm. Ideal for internal and external use. The anti-mould growth technology with added silicone helps limit mould growth and allow Projoint to repel water from the surface of the grout, while allowing vapour to pass through. The projoint grout is supplied in a bag to allow the branded bucket. Yub to be used as the ideal mixing vessel.

Available in three colours*- Neutral (Buff), Mid Grey & Black.

We recommend that the Projoint Porcelain Primer be used prior to application of this product.


Ensure the paving is firmly fixed and the joints are clean, free of dust, excess adhesive, bedding mortar or any contamination. Do not use in wet weather, and do not used if frost is forecast in the next 24 hours. Suitable for use in temperatures between 3 degrees and 25 degrees. Do not apply to areas in direct sunlight or to substrates that are hot.

Pro Joint should be mixed with 3 litres of cold water per 10kg bag. Remove the bag from the bucket and add the water to the mixing container. Add the powder slowly and mix using a drill and paddle until a smooth creamy consistency is reached. Mix for 2 minutes, allow standing for 2 minutes then re-mix. This process allows the polymer additives to dissolve and activate.


Use a rubber float to work the grout deeply into the joints until flush with the paving. Excess grout should be removed as work proceeds and any final residues left on the tile face can be removed by wiping off with a damp sponge up to 30 minutes after application. Ensure you have plenty of clean water for removing grout whilst wet/damp. Any dry film remaining on the surface can be removed by polishing off with a dry cloth when the grout has hardened in the joints. In warm weather freshly grouted joints should be kept damp when working outdoors using a fine mist spray. The pot life of the mixed grout is approximately 60 minutes at 20 degrees.


Approximate coverage per 20kg tub.
