Polymer render is a cement based system with carefully selected polymers added to the mix. These polymers make the finished coat strong and flexible, allowing them to be used on a number of substrates. Silicone water repellents are also an integral part of the premixed polymer/cement based render system. This silicone technology makes the render surface highly water repellent whilst allowing water vapour to pass through the render, letting the substrate breathe.
Acrylic render contains acrylic aggregates to display an attractive finish. It is applied to new and existing render to seal the substrate layer and enhance the appearance of the elevation. Acrylic renders incorporate anti-cracking technology through the use of minute reinforcing fibres to produce a very tough and durable finish.
