Should You Bid Floor Space Or Wall Space For Painting

In either case there are problems with this approach.
Should you bid floor space or wall space for painting. A 10 10 8 room would be a different price from a 10 10 12. You ll lose those inches in living space but it s. If you re using a single paint color on all of the walls make sure the paint looks the same on each. Crawl space foundations are easily waterproofed by gluing a thick sheet of plastic to the ground and walls.
Interior basement walls should be scrubbed free of mildew or mold and then primed with a waterproofing paint that is suitable for the surface. I agree that measuring the floor space only would make your estimate inaccurate. As one would require more prep more labor and more paint. Given the information above the paint sells for 29 a gallon when purchased in a 5 gallon pale.
You could loose allot of money bidding like that. Basically track houses since they are all basically have the same specs. Cutting in and rolling. In both cases they might use about the same amount of materials.
Unless of course you are painting the floors with porch floor paint then that makes sense. Two to three coats of a sealant may be necessary. You know your square footage of a room however. One home has a lot more detail than the other home.
As some wall will be higher than 8 feet. With an open floor plan the same large space typically has windows with different exposures. If you know your production rates you can bid by square footage. Imagine you have 2 homes that are both 2500 square feet.
I only give a bid for the floor footage after seeing the plans for the homes. Instead of apply paint why not use a plastic vapor barrier over the block wall in the crawl space. Do you know how long it takes you to paint 200 square feet of wall space. You can measure the perimeter of a room to calculate the wall area but if you already know the floor area of the room from floor plans for example it may be quicker to calculate the wall area based on that number if your room is square or round.
30 feet of chair rail. So you invest 145 to cover 500 square feet for 1 coat and 290 for 2 coats and 435 for 3 coats which is most likely the appropriate amount to apply. Sometimes contractors will talk about square footage about floor space and other times it will be about wall space.
