The ProJoint™ Pre-Grout™ Stone & Porcelain Paving Sealer is a professional-strength, water-based treatment designed to assist with grout and jointing compound release. It helps minimise the risk of resin sheen and grout haze after paving has been jointed.
This sealer should be applied once paving has been firmly laid on a suitable bedding course and prior to the installation of jointing compounds. It is suitable for use with all ProJoint™ grouting products and is highly recommended before installing ProJoint™ TITAN compound.
Once grouting has been completed and fully cured, the paving sealer can also be applied to help protect paving and assist with the removal of organic stains and surface dirt.

The sealer assists in preventing resin sheen and grout haze. It can also help with the workability of the jointing compounds; including air cure, epoxy and cementitious grouts.
As soon as the sealer has dried (30-60 minutes weather dependent), it is ready to accept foot traffic and is ready for installation of your chosen jointing compound.
This sealer uses a water-based formula allowing it to be used all year round.
To achieve the best seal, it is recommended to apply onto a dry surface, however it can be used if surfaces are damp.
We recommend 2 coats are applied to achieve maximum protection. You must wait for the first coat to dry before applying the second.
