FAQ's

  1. The instructions say to allow the primer to dry before application, is this correct?

    ProJoint Porcelain Primer is specially designed for porcelain paving, offering superior adhesion and durability compared to standard slurry primers.
  3. How long does it take for the primer to dry?

  4. Can the primer be used on natural stone?
    Yes, although it’s optimized for porcelain, it can also be used on natural stone.
  5. Do I mix a full bag at once?
    Only mix what you need. If you’re working on a small area, you can mix less to avoid waste.
  6. How long can you leave the cured primer on the back of the slabs?
    You can leave it on for up to 14 days before laying the slabs.
