Does anyone know what's involved in spraying a texture finish?
I think it requires a special tip(s)? Or does it take a special gun?
I have a small automotive touch up gun that I use often.....can I get a tip for it?
Tried searching the web for some "industrial paint supply" places but no luck.
THANKS for any help.
i think if you talking about the crackle effect or such??? then its in the paint.. the chemials make the paint bubble or crack and thats the way it comes out the spray can like the smooth finished do from the same can.......
large amount of paint out of the nozzle and tips that will feed paint with a minimal amount of atomizing.
If the application is not to picky, you can hook a pressurized garden sprayer to the fluid inlet of a standard gun, turn the fan control to zero, cut down the air and get a fairly good spatter texture. You have to experiment with air pressure to the gun and paint viscosity to get the spatter size right.

One method is to use spraycans of undercoating or an undercoating gun, they're cheap, then prime and color over it.
Here is a blurb from a PPG product: """"Note: Increasing or reducing the amount of thinner used will result in reducing or increasing the pattern (texture) of ROADGUARD. Over Thinning = Pattern Diminishes Under Thinning (Siphon Feed Gun) = Pattern Increases Higher Air Pressure = Pattern Tightens Lower Air Pressure = Poor Atomization Gun Distance Too Far = Coarse Pattern Gun Distance Too Close = Smooth Pattern"""""

Drywall texture? I think it's a special setup.
Get a spatter gun from HFT for $25.

For smallish items you can get 'stone texture' paint in a standard spray can -- from the 'art supply' store here. Works well, but isn't really a durable finish ...

Normally it's done with a gravity fed HVPL gun. First spay the base coat as you normally would. Wait about 15 min for the base coat to "flash" or film over. Then reduce the air pressure very low. 5 - 8 PSI works for me. Test your spray on some test paper and make sure the droplets are what your looking for. Normally you'll spray about 2 1/2 ft back from to object to get a good even coverage. Reduce the pressure to make the droplets larger, increase the pressure to make them finer. Clean up, go have a beer. :-)
