K-Rend HP12 Base Coat Render

K-Rend HP12 base coat uses ‘High Polymer’ technology to create a cost effective scratch coat with enhanced application performance on difficult substrates. The HP12 is ideal as a stipple coat or for dense backgrounds and has increased water resistance and adhesion. It is recommended to embed K-Rend’s Alkali Resistant Reinforcing Mesh into the HP12 base coat to improve strength and flexibility.

Coverage of HP12 Base Coat

HP12 Base Coat comes in 25kg bags and 1.8kg of the product is required per millimetre thick per m2

Therefore at nominal 4-6mm thickness one bag of HP12 will cover approximately 2.5m2

Application of K-Rend HP12 Base coat

  • Add 5-6 litres of clean water to each 25kg of HP12.
