Sorry, I know this has been done a couple of times. couldn't quite find what I was looking for on the other threads, other than "dont buy a cheap one" which is fine!

Absolutely must have a sprayer, no way I'm painting inside of a double garage by hand!

Needs to do a coat of dilute PVA first, then a few coats of paint.

Hiring would seem like a good idea, airless system would cost £200 for 2 days, god forbid I overrun it gets expensive.

However can buy one of these for £250-ish..

Looks fancy...

Or, get a compressor and some cheap gravity fed spray guns? If so, any hints on what compressor and guns? I think I like this option the best as I can get some air tools for bits and bobs in the garage at a later date.

Cheers

Wagner, £82 off E Bay (new)

It'll paint a garage with ease. Paint will need thinning to get a flat finish though.

PVA first?
Why's that?

What are you actually painting?

Do not PVA it, just dilute the first coat of paint.

Pva is a cheap attempt to stabilise the mortar, it's a bit crumbly.

I looked at "proper" stabilising solutions, £50 a litre put me right off.

From what I read it should work ok.

However if you're saying just give em a brush down and a thin first coat of paint that's cool. Less faffing around! smile

It's bare brick on the inside of a double garage, hence wanting to spray as my rough maths makes it about seven acres which I don't want to do with a roller!

Well, if you reckon they are good then I can get one of them AND a cheap compressor with a gravity fed sprayer and some other cheapo tools all in budget! Winner!

If you have loose and friable mortar then you'll have to stabilise it.

Just don't use PVA, no matter how cheap it is - you can buy stabilising solution for £20 per 5 litres.

Ah yes, you can indeed! Thank you!

Can I spray it? And what can I spray it with! smile

Yes, absolutely you can spray it.
Just give the stabiliser a good 24hrs to dry properly.

Whilst I have a small HVLP unit, I actually more often than not use a brush and roller on masonry surfaces as I can't be doing with the chance of errant overspray...

Any of the spray units mentioned should do the job.

If you use an airless sprayer you need some "flow stuff" mixed in, they don't like thick paint.

Inside of a double garage is about the smallest job you would use one for, I swear mine takes about a gallon to primesmile
You will spend about 30 minutes setting it up (getting the pressure right) to get even coverage. 20 minutes to do the job and one hour clean up.

Those small Wagners don't hold enough paint IMO. they like flow stuff to and they come with small tips so you'll need to strain the paint (pain in the butt)

Have you considered one of those wagner rollers, They use to call them "paint sticks", two types one electric, the other has a piston. Also great for doing ceilings. Manual one is all you need for a garage. Cheap enough to toss at the end of the job.

A rather annoying infomercial https://www.youtube.com/watch?v=09K4ZnDfBp4 just scroll through it.

Mine has a trigger to ratchet the paint into the roller much better than as it is more controllable.
