What is K Rend
K Rend' is often used in the external insulation business as a catch-all term for render. K Rend, in fact, is a brand with a large range of different renders, manufactured by Kilwaughter, the chemical manufacturer parent company in Northern Ireland. K Rend traditionally produced ‘thick coat’ renders such as dash receivers and monocouche and has recently also ventured into the family of silicone render products.
K-rend is a mineral-based product traditionally processed using limestone. It is delivered on-site pre-bagged. The company produces organic resin renders (or 'bucket mix') which come in over 500 colours. The range includes Base Coat for new block applications prior to finishing with an approved top coat, as well as Fibre Base Coat, a fibre reinforced version of the standard that can be applied by hand or machine where impact resistance is a premium consideration.
They also offer Backing Coat of a pre-blended sand and cement base coat that can be applied as an internal pargetting render and for basic external base coat applications. This is available alongside Overcoat Dash Receiver, a high performance option for general drydash applications. It can be applied by hand or machine and includes a silicone and an algae inhibitor.
This firm also produces Silicone Dash Receiver which provides a robust substrate for the traditional K-Rend Silicone Roughcast finish or a Decarock Drydash aggregate. Alternatively, Scratch Render can be troweled, floated and left smooth to get a full render thickness. The surface can also be brushed down with a clean soft brush to achieve an attractive broken stone effect.
Finally, K-Rend Silicone Roughcast is a traditional wet dash finish achieved with a fully blended product straight from the bag, with only the addition of clean water required. Silicone Thin Coat is an organic resin render which is usually hand applied to give a decorative finish.
