Proper pressure for spray texturing apparatus?

Need to know proper pressure for operating a spray texturing apparatus?


Just need to know proper pressure that I should use in operating a texture spraying apparatus.
Thank you Chris.

Chris, the rule of thumb is to run the sprayer at the lowest pressure that will effectively blow the texture onto the ceiling or walls.

Since the pressure required will vary depending on the the piece of equipment and the thickness of the media, I cannot be specific.

You have a regulator on your compressor. Set it for 70 PSI to start, and test the spray. Adjust the pressure down to as low as possible for the material being sprayed.

Once you have reached the lowest pressure where your spray gives you the texture you want, raise that level by 5 PSI to give you a bit of safety margin for thicker media.

Setting your air supply up this way will help the compressor efficiency by allowing it to cycle less often, and you will use less energy in compressing air.

Cheers,

Bill

Central Pneumatic nailer shoots too deep!

by Roger

I have a 46240 28 degree nailler by Central Pneumatic and it nails to deep. Is there any adjustments to help with this besides the manipulation of air pressure?
_____________________
Roger, is there not an adjustment dial or lever located near the trigger on this model of framing nailer? I know the newer models have this adjustment.

Yes, you can reduce the pressure, but that may not serve best in that if there isn't enough pressure the nail gun may not cycle properly.

It is best to operated the gun at the recommended pressure and adjust the penetration of the nail via the (usually) included adjustment nut or lever.

If there isn't one on this model, would you mind posting a comment here to let us know?

Thanks,

Bill

Texturing walls before painting...

by Mike

Going to be texturing walls before painting.

What hp air compressor should I use with a hopper gun for texturing walls and does tank size make a difference (2 gal vs 4 gal)

Mike, my home air compressor is a pretty small 1.5 HP unit, and it had trouble with doing stucco.

See spraying stucco from the site map page, under air use applications.

Yes, tanks size matters, in that you'll be able to spray a bit longer before the tank is empty with a bigger tank and you have to wait for it to refill. By the same token, it will take longer to fill.

I suspect you won't be happy with the results if you are using a 3 HP compressor or smaller. Maybe rent one?

Cheers,

Bill

Air needed for 5 gallon blaster?

by Glynn Hancott
(Ontario Canada)

CFM = cubic feet per minute – what is the volume of air that is required from my air compressor to effectively run a five gallon Sand Blaster?
_____________________
Glynn, we, myself and others who visit this website, can't help answer this question except in generalities as the flow and pressure requirements for any air tool, including your sand blaster, are brand specific.

Then, you don't say, but do you plan on blasting all day every day at work, or are you just doing a small job, a one off, for example?

The amount of blasting you will be attempting will have a bearing on the size of compressor and tank required.

I can't be sure, yet based on trying to blast with my little blast kit, my guess would be that for any kind of regular use, I expect you'll need at least a three, and probably a five HP sized compressor, with a 30-60 gallon tank.

That's just a guess, as you really need to find out what the specs for your blaster call for.

Cheers,

Bill
