Norcros Rock-Tite Porcelain Primer extended information
PREPARATION
The underside of the paving should be clean, dry and free from any dust, dirt or any other material which may impair adhesion. Suitable for use in temperatures between 3oC and 25oC.
MIXING
Into the mixing bucket add cold water to the correct level and gradually introduce the required amount of powder, stirring to blend the mixed primer to a smooth lump-free slurry. Mix only enough material that can be used within the pot life of the product which will be around 60 minutes – this will be extended in cold conditions and reduced in warm temperatures.
Norcros Rock-Tite Porcelain Primer APPLICATION
Apply an even coat of the slurry over the whole underside of each slab using a suitable brush or roller before laying onto the mortar bed whilst the Primer is still wet.
Norcros Rock-Tite Porcelain Primer is a cement-based product and therefore all tools should be washed with clean water immediately after use. Do not empty waste material into the drainage system.
STORAGE
