This process allows the polymer additives to dissolve and activate. Do not re-wet or add too much water as this may cause a weakening of the grout and may also lead to discolouration in the form of efflorescence.ProJoint Porcelain Grout ApplicationUse a rubber float to work the grout deeply into the joints until flush with the paving. Excess grout should be removed as work proceeds.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.We recommend the use of a washboy and sponge float to clean the grout residue from the surface of the porcelain and provide a smooth finish on the joints. Textured paving may need additional cleaning to remove once dry. 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.When working out doors, in warm weather any freshly grouted joints should be kept damp using a fine mist spray.The pot life of the mixed grout is approximately 30 to 40 minutes at 20oC.All tools should be washed out with water immediately after use. Waste material should not be emptied into drainage systems. Newly grouted joints should be protected from rain or frost during the curing process. Please ensure that 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 20oC and a full cure after 72 hours at 20oC. Please note that cold temperatures can delay the curing time. Categories: All Products, Exterior / Outdoor Use Self Levelling Compound and Paving Grouts
