ProJoint Porcelain Paving Grout
ProJoint Porcelain Paving Grout has been specially developed for laying porcelain paving, with joint widths of 2 to 20mm. This professional grade porcelain paving grout is ideal for both internal and external use. Utilising clever anti-mould growth technology with added silicone, ProJoint Porcelain Grout repels water from the surface of the grout, whilst allowing vapour to pass through.
The ProJoint Porcelain Grout is supplied as two 10KG bags, that are ready to mix, and come within a tub which can be used as the ideal mixing bucket.
ProJoint Porcelain Grout is available in four colours: Neutral (Buff), Mid-Grey, Basalt & Black. This specialist porcelain grout offers both DIYers & Landscaping Contractors, fast and easy application with really professional results.

We recommend using the ProJoint Porcelain Primer prior to laying porcelain paving.
Ensure that 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 (can be used if joints are damp) and do not use if frost is forecast in the next 24 hours. Suitable for use in temperatures between 3°C and 25°C. Do not apply to areas in direct sunlight or to substrates that are hot. A grout film and/or pigment stains, especially with dark colours, may remain on paving after jointing. Follow the paving manufacturer’s recommendations. A trial grouting area is recommended to check suitability. Only clean water and clean tools must be used for grouting and final cleaning. Never add water or fresh grout powder to a grout mix which has already started to set. ProJoint Porcelain Grout should be mixed with 3 litres of cold clean 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°C. NOTE: the grout will be considerably lighter in colour once dry. Newly grouted joints should be protected from rain or frost during the curing process. Care should be taken to ensure any protective cover does not come into contact with the fresh joints; air circulation over joints is required during curing. Cure times are dependent on temperature and humidity but as a guide can accept foot traffic after 3 hours at 20°C and full cure after 72 hours at 20°C. All tools should be washed out with water immediately after use. Waste material should not be emptied into drainage systems.
