Weberend Aid is a polymer-modified sand and cement mix, designed for use as a preparatory coat prior to the application of renders. The product enables users to create a good key on substrates that are especially smooth, enabling ease of application for the render topcoat and ensuring a longlasting adhesion. It also neutralises the absorptivity of the substrate, providing excellent suction control, as well as resisting water ingress and thereby improving the weather resistance of the entire render system.
Weberend Aid comes as a dry mix in 25kg bags. Mix three parts Weberend Aid with one part clean potable water using an electric paddle mix. It is recommended the render is mixed for 5 minutes to achieve the required consistency. Weberend Aid is then ready for use.
Weberend Aid can be applied using a hawk and trowel, or it can be applied using an open hopper spray gun. A tight layer of 2-3mm should be applied to the substrate before it is textured using a well loaded roller. For challenging substrates (low suction or dusty), scrub Weberend Aid into the surface using a small hand brush. The product should be left to cure for 3 days before the render topcoat can be applied.
Comes in powder form in a 25kg paper bag.
