Is there a constant that you can multiply the floor sq. ft. by, to get paint and primer, at say, 300 and 400 sq. ft. per gallon, for a given wall height??

Obviously, each wall height would have a different constant, and cathedral ceilings and whatnot would not conform. I'm just assuming that those of you who do painting exclusively must have a quick way to estimate. If it's not something anyone wishes to disclose on a public forum, I understand.

The closest I came up with is 153 as a constant, for 8ft walls. I need to run a bunch of other dimensions to see if that holds up.

I hope some of this makes sense. End of a long, frustrating, day.

This is something I never tried to do but people are always asking this question.
For material estimating:
The way I see it just keep it simple, you have to measure the floor to get a square foot area, why not just multiply the perimeter by the height and forget the formulas?

I never do labor costs by the square foot.

 

[Seven-Delta-FortyOne]

Yeah, I'm not talking about doing my whole estimate by the sq. ft., just figuring quantity of paint.

Like for a new home, it's 1,700 sq. ft., all 8' walls, if there was a formula, hell, you wouldn't even have to go to the job site, just multiply by your constant, add a little for closets or whatnot, and you'd be good.


I don't know, maybe I played with math too much as a kid.

 

[cleveman]

Yes, there is a multiplier.

 

[Seven-Delta-FortyOne]

Yes, there is a multiplier.

Well.........................

 

[Jaws]

The can is wrong.

150 is about right applied properly. Surface sq ft.

 

[jlsconstruction]

How would you know how many sqf of walls are in a 1700sqf house?

 

[Seven-Delta-FortyOne]

150 is about right applied properly. Surface sq ft.

Only 150?

I don't get the 400 they claim, but I'm usually between 3-350.

???????????

Really? I clock the plan, multiply by the height of walls.......

2 coats?

My hands may be stealing......

You watering at all? I dont.

That's what I do too. I thought he was asking for a way to figure out how much paint he would need just by knowing the sqf of the house.

 

[Seven-Delta-FortyOne]

True. You wouldn't. Bad example.

I was thinking more along the lines of going into a house, and measuring just the room dimensions, on the floor, and then multilying it by some multiplyer, solely for speeds sake. I just figured the Painters must have a shortcut, that's all.

 

[Jaws]

Maybe 200-225. Rolled, two coats , with PVA behind that. No spray for drywall.

 

[Jaws]

That's what I do too. I thought he was asking for a way to figure out how much paint he would need just by knowing the sqf of the house.

I knew I was missing something. :thumbsup:

Or I'm missing something, it's late :laughing:

Nah, its me. Im bidding too much. I see plans in my sleep :laughing:

I was dreaming last night about roofing, and woke up at 330 sitting up in bed then realized we would be framing today. Thank god :laughing:

No. I don't water. I always prime first, though. The first coat is always way low, second coat pretty much brings me up to average.

Always do two coats.


I'm in the middle of a whole house repaint, about 1800 sf, I'd guess. Gonna get some better numbers this time, and I'll report back. Been awhile since I did a whole house repaint.

Nah, its me. Im bidding too much. I see plans in my sleep :laughing:

Hope you get some of them. Any fun ones?
