Hi, I've built an extension and an outside wall is now inside. I want
to paint the wall white. The wall has been painted by the previous
owners with some thick black bitumen paint.
Trying to remove some using a wire brush on a drill or a 4" grinder
does remove some of it but leaves a smear that can be removed quite
well with a rag and some petrol!
There is a quite alot of this wall so:
do I need to remove this stuffbefore painting?
if I do, is there a quicker/better way than wire brushing?
Thank you
Job from hell. Nitromors type strippers work well, and aren't that dear
if you buy in bulk from a trade supplier, but the fumes will kill you
indoors.
ISTR that pliolite paints have reasonable adhesion to bitumen but you'd
need to check with

or similar.
