I would like to paint the outside of the rear of my house (front
already done when I moved in) and have a compressor and spray gun.

The gun is very poor at spraying thick paint or even fencing paint/

What do i need to spray thick paint? Would a spray gun with the bottle
on top of the gun work? (the bottle is on the bottom of my gun)

Hi there

don't use a compressor it wont do the job, i think what you need is a
High-volume, low-pressure (HVLP) paint sprayer, do a Google on them and see.
Let me know how you get on.

best of luck

You'll need an HVLP system, and a very expensive one at that. I looked into
it, and spoke to Leyland (I bought their paint) about spraying it,
specifically thinning it for spraying, and they said "don't thin it, you'll
ruin the paint properties".

I then spoke to a manufacturer about suitable sprayers, and they said that
despite some of their literature claiming to be able to spray masonry paint,
they really couldn't, however they were launching a new model that could -

Have spent more paying someone else to do it manually, but have saved myself
the time and hassle, probably used less paint and got a better job to boot.

bought a 600w HVLP sprayer from Ebay and it can spray fencing paint OK
though may need a bit of thinning however opening a tin of masonry
paint it would have no chance - if I thinned it so i could spray it
(probably requiring at least one or 2 parts water to 1 part paint) i
dont think it would set properly.

I've done the job with a masonry brush - slow it took 2.5 days for the
back of the house only but it's a good job and aside from it being
whiter than i wanted due to poor color labels by dulux it looks nice.
Next time I would investigate a masonry roller it may be quicker but I
would suspect use more paint since you can't really work the paint in
very well like you need to with a masonry brush. All in all took 5
tins or 10l paint to do the back of the house - it's pebble dashed =
£100 and borrowed scaffolding off a neighbour.
