Why should I use Pre-Grout Sealer?
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.
How long until the sealer is cured?
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.
Is the sealer water or solvent based?
This sealer uses a water-based formula allowing it to be used all year round.
Does the area need to be dry before application?
To achieve the best seal, it is recommended to apply onto a dry surface, however it can be used if surfaces are damp.
How many coats do I need to apply?
We recommend 2 coats are applied to achieve maximum protection. You must wait for the first coat to dry before applying the second.
