Mortar Mix

Our fast-setting mortar solution is suitable on a variety of surfaces in both interior and exterior settings – with no formwork required up to 150mm. Its high-build formula makes it ideal for many different types of general and structural projects, such as new builds, remediation, render/masonry repairs, mortar beds, off-form concrete, concrete cancer and pavements.

As the strongest and fastest render repair mortar on the market, CTS Rapid Set Mortar Mix® permeability and durability remain unrivalled. Whilst many traditional mortars deteriorate over time and in fluctuating temperatures and weather events, our high-build product remains stable and crack-resistant in all conditions.

CTS Rapid Set Mortar Mix® benefits


Specially formulated to harden rapidly, our cement render repair mortar mix can be ready to paint over in just 60 minutes.

Our high-build repair mortar is one of the highest worldwide, meaning it can be applied in a single 150mm build with no slumping. It has a customisable consistency too, trowelling to a smooth or textured finish depending on your application.

Compressive strength

When using high-strength mortar in areas where it will come under pressure (such as a supporting foundation, or in the ground where it will be walked across and driven over) it’s important that its structural integrity can be guaranteed. Mortar Mix® has a compressive strength of 17.2 MPa after just one hour.
