I have an external and internal wall to plaster / render respectively, I recently saw a chap apply a compound to both the internal wall (blue coating) and the external wall ( a red coating) which he said was to give a good ‘key’ and much better than plain old pva washes.
I forgot what he said the stuff was called - can anyone enlighten me and provide opinions as to its usefulness
thanks
