How to use Nexus ProJoint Porcelain Grout


  1. Nexus ProJoint Porcelain Grout should be mixed with 275ml of cold clean water per 1kg of grout. 
  2. Remove the bags from the tub and add the measured quantity of water
  3. Slowly add the measured amount of powder.
  4. Mix for 2 minutes using a drill and paddle/plasterers’ whisk, until a smooth creamy consistency is reached.
  5. Allow to stand for 2 minutes
  6. Re-mix for 2 minutes. 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.


  1. 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.
  2. 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.
  3. 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.
