K Rend HP12 Base Coat 25kg


HP12 Base Coat is used as a preparation coat for K Rend top coat finishes.


HP12 Base Coat can be hand or machine applied. It uses ‘High Polymer’ technology for an enhanced performance on difficult substrates such as dense block, unpainted render and brickwork (providing K Rend R7 Primer is used in conjunction with this). It is ideal as a stipple coat or for dense backgrounds and has increased water resistance and adhesion. Incorporation of Alkali Resistant Reinforcing Mesh may be required at stress points such as door and window reveals. HP12 Base Coat can be used in conjunction with all K Rend finishes including Scraped Texture, Thin Coat, Dash, Roughcast and Brick Rend.
