This follows on from a thread where I asked about using Polycell SmoothOver
to cover up a texture coated ceiling that we wanted gone. I received a fair
bit of advice about the procedure - most saying don't use the stuff, it's
hopeless. Others gave advice about sanding it down or getting it skimmed
Well, after the advice here, we abandoned the SmoothOver 'solution'. I had
already tried some stuff (forget what it's called, but it's a blue paste and
expensive) designed to shift it, but that didn't work either, so decided to
try and sand it down. I bought a load of sanding belts for my belt-sander
and began the process. After a short while it became quite clear that it was
(1) going to take forever, (2) very messy, and (3) not going to produce a
very good result.
I was considering getting someone in to skim over it, when I thought about
trying my hot-air gun with a scraper - as you would when removing gloss
paint. Actually, this works quite well. Time-consuming and laborious, but
definitely works. I have almost removed the stuff now, so can can quite
clearly say that - for me - of all the methods this is definitely the best.
