K Rend base coats recommended for use on medium density blockwork. The application of a base coat before the application of a K Rend scraped texture render on this specific substrate is not required although some applicators find applying a base coat does improve workability of the system due to working with thinner layers.
These base coats are recommended for use prior to the application of all K Rend TC finish renders.
K Rend HP12 is a high polymer base coat designed to provide enhanced performance on difficult substrates. The enhanced properties allow for increased water resistance and easier adhesion. This K Rend base coat can be applied either by hand or spray, though in some cases, the use of a scrim cloth may be required.
