The paint on my shed is flaking - some of it comes off quite easily with a
scraper but some is more stubborn.

As far as I know the 2 paint removal methods are a heat gun or somesort of
chemical that you paint on

What is the ebst to use outside?

The shed is made of breezeblock I think but the external bit is smooth so
I
guess it must be rendered or something....


When I repaint it I will be using masonary paint of course which can be
bought textured or smooht - will textured cover up bumps/cracks better?

I've never managed to get paint off masonry with a blowtorch/heatgun. Not
entirely sure why: suspect that the surface is too rough and porous, so the
solvent/wood resin vapours cannot build up to form the blisters that lift
the paint.

Not a job that I would want to be lumbered with, and I would imagine the
pros would bead blast. You might be able to clean it up with a power washer,
before repainting. Wire brushing a whole wall by hand would wear you out in
no time, and using a powered brush would leave metal over the masonry which
would make rust marks.

Powerwash would be my bet. (Watch out for any woodwork though, as a fully
focused jet will drill it.)
