Commercial Deck Spraying ? - Contractor Talk - Professional Construction and Remodeling Forum

CreativePainter · 05-26-2009, 10:29 PM

Does anyone know what would be production rate for spraying deck 25' off the ground with one coat of latex dryfall.
Number of sq ft per hour - spraying only - not including masking and ground help ?
... or app. estimated number of hours for 10000 sq ft.

According to SW coverage for their latex dryfall sprayed on the commercial deck is between 80-100 sq ft per gallon. Can anyone confirm this info.

Thank you in advance.

Does the 80-100 SFPG account for the corrugation in the deck? I bet it does.

If you are using a manlift I would think a man could spray on at least 5 gallons an hour with an airless. that would be 400-500 SF per manhour. If the area is cluttered it might be half that. You would be safe using 300-500 SF per manhour I would think. Maybe more. That would be 300-500 SF of flat area. The corrugation is figured into it.

That would be about 20-30 manhours of blowing and going all 1 color.

on a corrugated deck with steel joist one guy can spray 3,000 sf per day.

not all decks are paintable with dryfall. is it galvanized? if so check it with copper sulfate to make sure there is no film buildup you have to clean.

some pre painted decks can't be painted.

whats your prep? blow down?

tell your rep to test it to make sure the materials he is specifying are compatible with the substrate. Dryfall goes for $0.55 to $1.00 per square foot depending on the prep, size, material, accesability, cover up, etc.

It is corrugated deck with steel joist. It is brand new construction, and i believe that deck has been factory primed with gray primer. I came up with $1 per sq foot including materials, masking and ground help. Lift will be supplied by GC. Thank you everyone.

$1 per square foot is a little high.

some factory primed decks are not coatable. the material will peel in sheets after only a few months. I can't remember what the deck material is called. you should make sure before you start the job.

I travel and paint them for around $.76 and with them providing the lift I would do a 10,000 sq. ceiling for around $6,500.00. A buck a foot is to high for anything over 4000 sq. ft.

Edit to add:
A buck a foot is not to much for an area where you are covering a bunch of stuff and working above and around lots of stuff, I have charged as much as $3.00 per sq. ft. for a couple of these jobs over 4000 sq. ft.

Figuring corrugated deck with standard height joists, 50' x 50' bays:

For an experienced sprayman that does a lot of decks: 2 days spray time, 160 gal material (big pumps, big tips), plus whatever prep time you need.

For an inexperianced deck sprayman: 4-5 days spray time, same material, plus prep time.

I would recommend the latter for you.

Your labor rate x 5 days spraytime + 2-3 days prep time/ cleanup
+ 160 ish gallons material cost

oh yeah, don't forget sundries cost....and use aluminum foil on those sprinkler heads.

Blown tip = twice as much materials... Hand on the trigger 100% of the time = 3 times the materials. Non covered or broken sprinklers = - roughly $250.00.

... one of your employees driving the lift into a sprinkler head, emptying 100,000 gallons of water into a adjoining furniture store, hardware store and chuck-e-cheese's = priceless.

you can negotiate special pricing for SW waterborne dryfall with your rep

it should be well under $10/ gallon. i know a shop that gets it at $7.50/ gallon. then again, they buy over 10,000 gallons a week during peak season so they get the royal treatment.

material's cheap, labor is not.

big pump, big tips, max pressure, don't let go of that trigger,

do yourself a solid and invest in a full faced respirator, a pack of tear offs for said respirator, a few spray socks, and a few tyvek suits.

Nav, I gotta do some commercial decks. but they have light grease on them. What is the best way to prep? I was going to use an oil-based dryfall or a modified epoxy. How well would the job last if I sprayed an modified epoxy over greased up decks.

At least a month.

Clean it first and then shoot it.
