As far as I know the 2 paint removal methods are a heat gun or

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?

A quick wire brush to remove anything loose, and just paint over. Its
one case whre it simply isnt worth making the job 4x harder for the
sake of 25% longer paint life.

If you want white, lime paint fills cracks, can be used to smooth
breeze blocks, is as cheap as paint gets and lasts
ages.http://wiki.diyfaq.org.uk/index.php?title=Paint

Phew, what a big wiki! The lime section seems to be the most expansive:
plenty of room for additions elsewhere, but remarkable scope. Is
'builder's
lime' slaked lime or 'quick' lime? Does a limewash have to be aged
before
use (lime putty I seem to recall, taking 6 months, on the restoration TV
progs)

S

btw lime is also antibacterial, fungicidal, and acts as a mild
stabilising solution.

All very enlightening thanks.
Now would this be the same 'paint' that is used on all those miles of
white
picket fences in the US tv progs and films?
And might this stick to our small picket fence that has been glossed but
needs frequent redoing due to car splashes and algae?

Cheers,
S

I've no idea whats used on US picket fences. If I were to paint such a
fence I wouldnt choose simple lime putty though. There are a huge
number of lime based paint recipes, varying from paints that have
lasted centuries to temporary paints like whitewash. If you're
interested I'll see if I can find more info.

Simple lime sticks to lots of surfaces but not everything. If it
doesnt stick initially one can add 1% linseed oil.

NT

Won't that just float on the top or form lots of little balls?
Yes, I've often wondered about those picket fences: I made one small one and
it was a lot of work, and then the first lot of expensive fence paint just
fell off, so I just use ordinary gloss: but I don't believe that would ever
have been an option for the miles you see on TV.
