Topic # 185826 7-Dec-2015 10:36

We are wanting to spay paint some pine furniture that looks like refugees from the 70s/80s. We purchased a Airless Spray gun from Mitre 10 but when we got home we noticed in the fine print that it says its for things like
spraying garage doors, fences etc.
Now I know next to nothing about these devices, will this do the furniture or is there a reason it wont? do I need to get a different spray gun to do this sort of work?

Angle that they will work at can be a problem.

I got one to do the cieling of a garage, all the beams for upstairs and the particle board were a pain with a roller because of all the corners. Problem is as soon as its pointed up, it stopped working. Just started to chuck out giant globs of paint instead of an even stream of small bits.

Its to do small jobs like a couple of dressers, a coffee table (aka shin destroyer) and two side tables. I /we can do this I think with out pointing the gun upwards. It will point downwards a bit though .

See how it goes. Also the paint has to be the exact thickness to work. Tiny bit either way and its either like painting with milk or else it just dribbles out and down the front of the gun instead of spraying.

I think the fence behind the garage is going to have a bit of test spray on it :)

I take the garage doors, fences, as an indicator of small, consumer jobs. I guess you could paint a house if that was done in bite sizes pieces. Good to know about angles though. Very handy for inside cupboards, but maybe not if it needs to be horizontal as you couldnt paint the under shelves. Or could you get round that with a consumer spray setup that had a seperate paint tin or allowed an extension to a hand held tin? Im assuming the reason is only that the paint pickup gets air at an angle?

I would assume that the spray is not super fine so on smaller items might not give a perfect finish. It might be a good option to throw on a quick primer coat but if you care about the final finish being top notch I wouldn't be using something like described.

I will need to put a stain sealer undercoat, I may resort back to plan A that was to use fine rollers

I would say what you have bought isn't designed for use with furniture as normally you have to spray the underneath which means the spray angles would case issues, for anything thats not up & down and side to side get an air compressor with the correct attachment.

A compressor, is that air and paint spray or can you get airless guns as well? Which is better? Airless or air?

One person supports this post

The guns for compressors I have cant do anything as thick as a water based paint, and my experiance trying to spray normal dulux type enamels was a disaster. With car paint, great, and that is my prefered thing for furniture since it sets so much faster and isnt offgassing for a month like cheap enamel from a hardware store.

One thing to note - the airless sprayers - brand often doesnt matter too much - go for watts of the motor. They all seem to get a bit warm if you do bigger jobs and as they warm I find you need to stop and clean the nozzle a bit more as the paint is setting - to help avoid this once it gets used a bit I often water the paint down just a smidgen more.

In saying that I love airless spray guns - I've used it for outdoor furniture and even for spraying stain onto retaining walls (works really really well here FYI).

Yep - tried this multiple times with a multitude of different spray guns I've got quite a good compressor at home and you cant use housepaint at all.

I sprayed several internal doors, a cheap dining table, and more with one of the cheap wagner handhelds from mitre 10. worked great. Need to get the paint to the right consistency - takes a little practice at first, but once you get it right then its easy to repeat and you can get an excellent finish for a cheap price. The small units are easy to clean too.

The bigger airless sprayers are awesome if you want to paint a whole house. No problems with pointing upwards because they suck paint directly out of the pot.

Nothing could be faster*, they are amazing. Bit of a bugger to clean though....

* Perhaps the Mr Bean trick, if you could get it even enough :)

You can do it if you are able to move the furniture rather than change the angle of the sprayer.

For small parts you can hang them on string and spin them as you paint them.

Obviously you can't hang a dresser on string but the principle applies.
