Looking for a little guidance here... I have a project for work that is requiring me to construct about 11 large floor (6' x 4' x 26.5"H) cabinets/stands for animal enclosures that will eventually be painted black and have all of the edges on the six sides trimmed out in rough cut 3" cedar trim. 7 of the 9 cabinets are framed, skinned and sanded (waiting on exact dimensions on the final 4)
In the past I've built 2 of the same design as spec'ed for this project. For those I rolled the black paint & sponged Watco Gloss Wipe-On Poly on the rough cut cedar to get the level of finish on the trim I desired. Those turned out really well, but hand applying sponging Watco on the rough cedar trim very time consumptive. Given the sq. footage of plywood I need to paint black, and more importantly the volume of rough cedar trim I need to finish I'm taking a go at learning how to spray finishes.... and of course because my department is the red-headed step-child of our municipality I'm having to do this on the relatively cheap...
Because of the reviews online and because of the price point I picked up the following gun to play with as a starting point for experimenting:
- Central Pneumatic 20oz HLVP Gravity Gun w/regulator (AKA - The Purple Gun @ Harbor Freight)
- Can't remember tip orifice at the moment (1.4????)
- 15-45 PSI
- Air Consumption: 12 CFM @ 45PSI
- I also have on hand 2:
- Rigid 6 gallon pancake compressors (3.5 SCFM @ 40PSI / 2.6 SCFM @ 90)
- 1 10 gallon air tank
The above is my starting point to play with what I might actually need with an understanding that I more than probably have less compressor than I really need. My question is what gallonage/HP/SCFM would I actually be looking for in a compressor to HLVP spray latex & poly finishes on non-commercial/casual basis for things like a 6'X4'X26.5H cabinet..... where price point for equipment is a HUGE consideration? (I'm emphasizing that because I along with others enjoy spending other peoples money on this forum
)
Would something like a:
- McGraw 21gallon Oil-less, 175PSI, 4.0 SCFM @ 90PSI, 1.5 hp get me to where I need with taking breaks for the compressor to catch up?
A note here about usage: The volume of work I currently have to accomplish is a one-time thing and as a result of a whole facility renovation. While I anticipate building more cabinets in the future that would be as singular, spaced out projects... And while I do a fair bit of wrenching/wood working, aside from the need to getting into spraying my case usage for compressed air is very very low... I hardly ever use either of the 6 gallon compressors we have on hand. I don't expect to get into needing to use other air tools.
I also do understand that there are a number of other factors in play here that I will have to experiment with notably: acquiring a inline air-dryer, either thinning the material to be sprayed and/or modifying the tip size of the spray gun (or getting a better gun), as well a understanding spray pattern & using PPE. I'm just looking for some guidance as it specifically relates to spraying and understanding required compressor size/capacity.
