Friable surfaces will need to be addressed before any works can be started.


 Friable surfaces - hand   

A friable surface is one which rubs away when you rub your hand over it.  Examples include weathered cement rendering or old weathered brickwork ( known as spalled ).  If paint is applied to a friable surface, it will begin to come off with the crumbly parts after time.

A stabilizing solution will be need to applied first to prevent a crumbling surface coat.  First brush down the surface with a stiff brush or scrape back with a metal scraper, which will remove any loose debris.  The stabilizing solution can then be applied, which soaks deep into the surface acting like a glue, binding it down.  A good paint finish is now possible.
