Title: Render cleaning help needed please
Post by: Andy Foster on August 02, 2007, 01:16:00 pm

Hi

I have been asked to clean the render on somone's house which has been stained by water running off lead flashing and other general weathering soil.
I am going to steam it using low pressure steam and am happy that I can get the weathering off, but have had problems with lead runs before.
Does anyone know of a method for removing the staining caused by lead runs please?

Thanks

Andy

PS - It is coloured render rather than painted so custy doesn't want to have to paint over any unmovable stains.

Try brick acid or toilet lime scale remover ie greyland acid scale
