Our Service

K-rend is a silicone range which incorporates silicone water repellents as an integral part of the cement based render system. 

The silicone technology imparts a high degree of water repellence to the render surface whilst allowing water vapour to pass through the render and let the substrate breath..

The water repellent surface ensures a freshly rendered appearance for prolonged periods. The finish is drier and thus more resistant to algae growth.


Depending on the condition of the building, area in which is to be rendered. There are several ways in which the building has to be prepared before receiving the top coat of K-rend.

If the building is painted

All loose and flaking paint is scraped or grinded back before receiving a scratch coat of polymer render with waterproofer in.

Pre-existing render or pebble dashing

Blown pebbledash or crumbling render is to be removed and the bare surface is washed down. As with painted surfaces there is a scratch coat of polymer render with waterproofer applied.

Fixing corner & bellcast beads

U.P.V.C corner and bellcast beads are fixed to doors, windows and corners during or after the scratch coat is applied, thus leaving clean edges when top coat applied.

K-rend application

Once the defected render or paint work is removed and the scratch coat has been applied, the surface is ready to receive the top coat of K-rend coloured mortar system.

Using a darby or straight edge the top coat of K-rend is applied to the ready prepared surface at a thickness of 16mm, from this there are a choice of two finishes to the render.

Sponge finish

At the correct time a sponge float is used in tight circular motions which leave a smooth uniform finish.

Scratch finish

After 2 to 36 hours a float known as a nail float is used in a tight circular motion leaving a rough uniform finish.
