Norcros Rock-Tite Porcelain Primer extended information


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.


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.


Store in dry internal conditions away from direct sunlight between 5°C to 25°C. The product has a 12 month shelf life from date of manufacture.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
