Palace Chemicals has relaunched its new improved Rock-Tite 3-part system; the Rock-Tite Exterior Porcelain and Stone System comprises a primer, a mortar and a choice of brush-in or flow grout. The mortar is available either as a pre-blend or a concentrate that requires the addition of sand, as the user prefers. 
The first component of the system is the Rock-Tite Porcelain Primer, which is supplied in three 5kg bags, complete with a 15kg mixing bucket. This is a fibre-reinforced, polymer- modified, cement-based primer, designed to improve adhesion when used with porcelain, stone and other low absorption types of paving.
Secondly there is high strength fibre-reinforced Rock-Tite Mortar. There are two mortars available – either a pre-blend 20kg version, that very easily just mixes with water or a more traditional version, which is supplied in a 15kg bag that mixes in a 1:6 ratio with sharp sand to create the ideal bedding mortar for all external patio projects.
