K-Rend scraped texture renders are IS0 9001 approved and are BBA certified.
Our general method for obtaining a smooth or flat render is to use Silicone FT Fine Tex Scratch Render. This can be troweled and floated and left smooth, although we would always advise that it be textured to remove any blemishes or lime bloom. The preferred option is to apply Silicone FT to a full render thickness and then to float or scratch this render. Additionally, the fine grading of this material leads to a very fine textured render that is ideally suited for a JUB paint final coat in your desired colour if required.
Silicone FT (hand applied) 25kg bag is a fine scratch render. It is applied to slightly more than the finished thickness required and after an initial set has been achieved, a scratch render float is passed over the render removing 2 or 3mm. The surface is then brushed down with a clean soft brush to achieve an attractive broken stone effect.
Approx Coverage: 1.6sqm/bag@10mm or 1.0sqm/bag@16mm
Silicone “E” Grade 25kg bag is the machine applied version of Silicone FT offering the same fine broken stone texture but can be applied very quickly to large areas by machine instead of by hand. It has all of the same attributes as the hand applied product with the inclusion of silicone for improved water repellency and an algicide to reduce algae growth and improved dirt resistance. It is normally the applicators choice as to the selection between FT or “E” Grade Scratch render as the both offer the same high quality render finish once applied. It is the method of application that is the difference between the 2 products
Approx Coverage: 1.0sqm/bag@16mm
K1 (hand or machine applied) 25kg bag is a fine scratch render that can be applied by either hand or machine. Once finished, it will leave a fine broken stone effect slightly finer to the Silicone FT or “E” Grade finish but still with excellent weathering characteristics.
Approx Coverage: 1.6sqm/bag@10mm or 1.0sqm/bag@16mm
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. Incorporating a 4-6mm limestone aggregate, this render is applied over a coat of silicone dash receiver in the same colour as the top coat. With the inclusion of silicone and an algae inhibitor, this is a high performance take on the traditional wetdash finish. Available in the complete range of K-Rend colours offering a full through coloured render.
Approx Coverage: 2.5-3.5sqm/25kg bag (subject to the texture of coat applied)
