Stormshield Silicone Render System
High Performance Key Coat Primer
Johnstone's Trade Stormshield High Performance Key Coat Primer is a high polymer render that helps render basecoat adhere to old, problematic surfaces (non paint).
It is a modified, cement-based solution with fibre reinforcement, so it is specially developed to aid adhesion of render to difficult masonry substrates.
This Stormshield primer should only be used as part of a render system (applied directly onto masonry surfaces in a Stormshield Render System).
Weather conditions are crucial for application do not apply if frost is forecast within 24 hours, in wet conditions or when the temperature is either below 5 degrees or above 30 degrees Celsius.
