Given I dislike painting is it worth getting a cheaper sprayer for painting the walls of my garage? I have heard painting breezeblock is a PITA but is a cheap sprayer going to be useless? Any thoughts?
Having recently done this job, I found a roller to be completely useless, but a really wide brush very effective. I believe they are called a 'block brush', which makes sense. About £4.
A sprayer would probably be very quick, but £50 for a one off job? I'd rather spend it on biscuits.
Masonry roller for £6, watered down cheap paint, 2 coats (or 3 if you want it perfect!)
i tried a masonry roller and it was crap.
Gave in and did it the hard way with one of those stiff fat square masonry brushes that you use to work the paint into the cracks. It was surprisingly easy and didnt take half as long as i thought it would, as you can just daub it on unlike on a plasterd wall.
I have this sprayer, it's pretty ace actually
I've been using it to spray a wood paint which in theory is waaaay too thick for it and it's worked great. Also some nice touches in the design, it's very easy to clean and the paint pot has a proper sealing lid so you don't need to empty it between coats, just take it off the gun and lid it. I love it tbh. But it does create an incredible amount of spray in the air which settles everywhere so you need to totally clear the space out, sheeting things doesn't really cut it.
Though, in the garage I just used a foam roller because I didn't have the spray gun at the time.
I have one almost identical to that one /\/\/\
Just make sure you strain the paint. Don't ask me how I know.
I have heard painting breezeblock is a PITA
It's a lot easier / quicker / takes less paint if you give the block a coat of cement wash first (just a sloppy mix of Portland cement & water brushed on).
Interesting, seems like you don't have to spend too much. £50 for one job would be a bit much but I'm thinking it may be good for our fence panels and decking which will likely have to be done soon and we currently have a house which is 100% magnolia. As I said, I hate painting but if this works well perhaps it would encourage me to get on and paint the rest of the house.
Just done mine. Used a masonry roller first which left a lot of gaps. Then used block brush to fill all the gaps. Finally roller over for third cost. Really good finish. Yes it’s a PITA but full day, radio on and superb solid white finish. I did buy a quality paint as opposed to cheaper thinner option.
Then to pub to spend the money you saved 😀
As tilly dog says a slurry coat first, you'll get a better finish as well.. I bought a s****y wagner Pro sprayer when I was doing my house.. Awesome..
Hire the right kit from the local hire shop. Not adding more cheap plastic tat to the planet, use the kit that is designed for the job, do it in a day. Go riding.
Spraying blockwork is OK but the only way to properly flood out the holes is with a deep pile roller in my experience. Kinda works if you apply the paint with a spray then back roll it, cleaning out the spray is a right faff though.
For those with sprayers, if you were painting an internal room would you use it over a brush?
Halifaxpete makes the point I was going to.
For rough and porous substrates is a pain. The sprayed paint doesn't work its way into the surface. Industrially you end up using something designed with good wetting properties (which normally means it goes on really thin) or you use a more mechanical means like a brush. It is still standard practice to stripe coat (with a brush) rivets, bolts, corners etc. on things as large as ships to ensure good coverage and wetting.
I've never had much luck with spraying, mess from overspray, masking up and then clogging.
When I did my garage I did a first pass with a thick pile roller and then went over it with the biggest brush I had. It's not as slow as you would think.
Never used a sprayer, but when I did my old garage that was a roller and big brush.
Need to do this one, but it's now full of stuff...
Cover in timber then paint if necessary. Much quicker and less heartache, though a tad more expensive. I actually considered using white faced hardboard for mine til I worked out the cost 🙁 still wish i had
did mine with old emulsion (this was a mistake i should have used something oil based) a roller and a brush.
brush is by far the best method imo.

Probably not, just because of the clouds of paint smoke.
Would one of those sprayers work with masonry paint to cover pebble-dashing?

I had my entire house plastered, used a Wagner one to give everything a mist coat, was an absolute dream. Then painted everything white - perfect! Figured that was so good I'll do colour. DO NOT DO COLOUR.
The overspray is crazy and gets everywhere, had to repaint the ceilings etc - I also had all my floors up and there's no way in hell I'd ever do it with a carpet or decent flooring down.
I dislike painting
Make it fun. Empty the garage, loads of paint tins and a load of bangers. Sorted.
Sprayer for garage, shed, fences...

Would not use it inside unless empty house as radbikebro said
Got to say that we didn’t have an issue with penetration into breeze block walls in our workshop. Roughly 60m of blocks 2.4m high. Painted in 2000, mostly still looking good.
Airless sprayer from hire company, drop the pipe into bucket of paint hey presto, easy to clean too. Doddle of a job.
Overspray can be equipment, setup and paint dependent. I guess cheaper stuff where you can't change your nozzle apparature or tips size is harder to optimise?
Last time I sprayed with one of these, years ago now.
Probably only just get it in my garage!
So I got round to doing a watered down first coat and a 2nd coat on the one wall of the garage that is breezeblock this weekend. I tried a block brush and a masonry roller but both leave large gaps where they can't seem to penetrate deep enough to get the paint on all the surface. As it is it's looking pretty patchy. Im not sure how much difference it makes though, my primary purpose was dust control and to brighten it up and it's doing both I guess. Not sure if I call it done or of I'll alway wish I had done it properly (by buying a sprayer)

Like I said above: Brush it over with a cement wash first - it fills up all the holes so the paint goes on far more easily and you use much less paint.
