K-Rend R7 Primer 5ltr

K Rend R7 Acrylic is a primer used to go onto difficult substrates such as brick in preparation for our K Rend HP 12/HPX Base Coat which is applied whilst the R7 is still tacky. R7 Acrylic can be applied using a roller or by hand. This modified acrylic emulsion is used to improve the adhesion of K Rend renders to difficult substrates where the background does not provide sufficient key or has poor suction characteristics. The material is usually diluted before use.
