M.R. Stabilising Solution


M.R. Stabilising Solution is recommended for pre-coating and stabilising surfaces prior to the application of insulated renders. It is pigmented blue to easily identify application to all areas, but a clear solution is available on request. It is specially formulated for sealing powdery or unstable surfaces, normally following the application of M.R. Fungicidal Wash. The finished coating is weathertight when cured, but will freely allow transmission of water vapour. Life expectancy rating is in excess of 30 years.


Protect all areas not to be treated – approaches, fenestration, completed works, etc. – from splashes with polythene sheets or alternative methods.
