The ProJoint Porcelain Grout in Black has anti-mould technology while the added silicone ensures that water is repelled from the surface of the grout while still allowing vapour to pass through. It works for all joint widths between porcelain paving of 2-20mm. The grout comes ready to use and two 10kg bags are supplied in its own mixing tub to make the process simpler. ProJoint™ Porcelain Grout should be mixed with three litres of cold clean water per 10kg bag.
When laying porcelain paving a good foundation, mortar bed and jointing material are all vital.

Do not use this grout outside in wet weather or if frost is forecast in the next 24 hours.
In warm weather, freshly-grouted joints should be kept damp when working outdoors using a fine mist spray.
Once laid, it takes 24 hours at least for the freshly-paved area to dry so do not walk on it in that time. Leave for longer if possible.
