    Hi all just a quick question for a total newb when it comes to rendering etc. I have brick walls that once had old black mortar render applied to them and was wondering the correct way to apply a scratch coat to this.

    What is the best way to clean the brickwork prior to scratching the walls? Some say just wet it before applying the new render others say wet first leave to almost dry fully then use pva wait till tacky etc then apply the render.

    Could someone please fill me in on the best and most common procedure. Best brick cleaning method, best method of applying with adhesives etc.

    Thanks in advance.

    Pva is used to control the suction when using gypsum plaster, damping down the walls prevents the render drying out too fast and cracking.
    im assuming this is internal walls..why do you want to clean the black render from the wall?is it black render or soot?

    best post a pic.
