I am aware this is not strickly a woodworking question but bear with me. I have just bought a new house in a bad way and I am starting to get some work done. Obviously getting my garage/workshop done is a priority before the kitchen,bathroom or other such frivolity (wife not really understanding this) In order to speed up things such as varnishing the skirting I have decided to invest in a HVLP kit, or that is my excuse anyway.
I would like to practise some spraying first and thought it might be a good idea to paint the walls in my garage workshop white. These are brick and my question is what paint could i spray them with? I am aware that i could roller them, but where is the fun in that.

are the walls internal or external?? not sure whether you can thin external paint properly whereas internal paint can be for instance thinned with water, if you use emulsion. you need to find the best thickness of paint to flow through your spray gun. hope that helps paul  |

Its a Garage built into the side of the house, so i guess you would consider it as internal.

ok, so you will need to clean up and then surface coat the walls to ensure adhesion. as long as every thing is ok, then you could use watered down emulsion. paul |

Spray on a mist coat (brickstill grinning through) first and go over this again before it 'cures'. Improves adhesion and cover of the brick's colour.

I had the same idea of spraying garage walls (I have an Earlex HVLP) using masonary paint.
Asking advice on a DIY forum the general consensus was that spraying not the best way. It was claimed that even the high spec systems not very good and the better way would be to use a roller.
In any event the wall should be primed first with the finish diluted with water (or thinners for oil based). It was suggested that emulsion paint should not be used as a primer unless that was going to be the final finish.
If you do go ahead with spraying I would be very interested to hear how you get on as I still have to get around to doing mine ;D

I must admit that I've never used a spray gun, but using one to paint a garage wall seems to be an unnecessarily complicated way of doing a relatively simple job. Rather like those adverts on the TV recently of those spray gun systems to apply wood preservative to your garden fence - I can see a few neighbourhood disputes happening when someone finds their washing on the line covered in Cuprinol  ;D Cheers Paul |

I had a go and it failed with a capital F. The mix (smooth masonary) was originally too thick and would not spray. Then when it was thin and would need alot of coats, it was a bit pitifull and I continued with a roller.
I have to say I was glad I tried but it was a fruitless challenge.

Often the way with the "techie" approach - it turns out quicker to do it by hand. I bet a brush would have been even quicker than a roller!
Hadn't looked at this thread before, I assumed it was about urinals ;D.
