Spraying exterior paint

Pop into your local branch of Brewers decorators merchants.

They can give you good advice on what type of sprayer and which paints to use and I'm pretty sure some hire shops hire the sprayers out.

You will probably need an "airless pump" ( no compressor needed,paint is just pumped through the machine) to spray rather than HVLP (High velocity-Low-Pressure very fine mist of paint with a fair amount of overspray) or air-assisted-airless pumps (mixture of airless and HVLP).

You don't get massive overspray with HVLP, it's different to compressor sraying which I agree is a messy job.

I thought I'd just give a bit of an update to this.

When we went to buy the next thirty litres of the top coat colour there was a Bosch sprayer very discounted. While its just a diy's thing DH thought it would be a good think to have for other jobs and to give us the idea of whether the idea was worth perusing or not.

We've been doing the undercoat in white by brush (in fact, my employee has, and not doing that great a job tbh but DH only has so much time...).

The first thing I'd say about this thing is that its super light. I am a weakling and not very full of vigour and I managed to use it for a couple of hours. Its incredibly, incredibly economic compared to doing it by hand. Over the course breeze block we are painting I'd guess it will pay for itself in one wall of paint tbh.

Its quite hard for not very good painter like me to get the hang of even coat though.

It did make a little mess, especially as it was quite breezy yesterday but nothing horrific, so maybe 'proper' ones are something different, but this didn't get anything on our 'dog car" which was just fifteen metres away. (We moved the other car heeding the advice , just don't care about the dog car)

The decision now is whether we use this lightweight DIY one or hire a 'proper one' ! I think we'll probably keep going with this over a hand painted under coat for a while, but if we get a proper weekend we can dedicate to painting we'll hire one and DH will use it and I'll plug away with this thing.

Sounds like a real chore LIR, still it may only need re-painting every 4 years or so.....:rotfl:

Sorry, couldn't resist

I reckon it will take us six years to get round the first time. At least
Its a fairly low priority job.

If we do it faster its a huge bonus!

We're got g for a different colour on some walls just for a break....its a gorgeous colour but....monotonous! The white undercoat is retina burning though, where we are used to grubby grey breeze block.

We did the exterior of our pebble dashed semi with a macallister sprayer. It was about £80 from b&q. It was excellent, did a marvelous job. You have to thin the paint, it comes with a simple viscocity cup so you know when it's at the right consistency

It took us one whole day, 4 masonry brushes and an entire tin of pain to do an area about 4x2m by hand. The next day I bought the sprayer and we'd finished the whole house by the end of the second day. I'd definitely recommend it

Saying that, I was chatting to one of my decorating buddies and they say there are some paints where the instructions say "you must wear sunglasses to protect your eyes" because of the glare I would imagine.

I know some sprayers require the paint to be thinned but paints can only be thinned down so much before they won't protect properly.Did you manage to spray the paint without thinning down LIR?.

No, we thinned. But we have already painted with the undercoat by hand (which has a supposedly long endurance ...though not sure they are expecting it to be on breezeblock on a working yard ). The colour coat is I suppose decorative.

DH says he's going to take over the undercoating because he wants a better finish than we've got as its the important one.
