How to use Nexus ProJoint Porcelain Primer


  1. ProJoint Porcelain Primer should be mixed with 2.8 litres of cold clean water per 10kg bag.
  2. Remove the bags from the branded bucket and add the water to the bucket.
  3. Add the powder slowly and mix using a plasterers’ whisk.
  4. Mix for 2 minutes.
  5. Leave to stand for 2 minutes. This is important as the process allows the polymer additives to dissolve and activate
  6. Re-mix for a further 2 minutes.


  1. When wearing appropriate PPE, apply a thorough and even coat of the primer as a slurry using a masonry brush or roller to the underside of the paving. The pot life of the mixed slurry is approximately 60 minutes at 20o C.
  2. The primer should be completely dry prior to laying the paving. Depending on the temperature and moisture, the primer will be dry within 10 to 15 minutes, however the primed slabs can be left undercover and dry for up to 2 weeks prior to laying.
