Hey guys and gals,
I usually reside over in the masonry forum but I thought I would sneak over here and try to get some collective wisdom.

I'm sitting here doing a bid for a guy who wants a block Polo ring 300' x 150' at 5'4' tall. He wants me to do it all meaning the footers, laying the block and painting the whole thing white.


Whats the best type of paint to paint Concrete block?

How should I charge for this and how much? The whole thing would be about 10,200 square feet.

Thanks

Prime the block with a masonry primer. This is one example.
For a finish, double-coat it with a high-quality exterior acrylic semi-gloss. Any sheen will work, but I think semi-gloss is better looking on block, and will clean up/hose off easier.
An example of the finish coat.
Pricing I can't help you with. If you aren't a painter by trade, that will be a pretty hefty job. I'd sub it out to a good paint contractor.

Thanks PWG.
Probably sound advice only problem is I don't really know a good painting contractor and I do have the labor force to do the job, just no idea how many gallons to figure or how long it would take 3 guys to do? If I can get a reasonable price in there for bidding purposes I will be happy, just enough to cover my expenses and make a little. I'm not looking to make a killing on the painting as there is lots of other money in the laying of the block as well as other projects linked to this one.

there is a product called blockluster by maxum its a high build block filler and it dries to a satin finish that needs no topcaot,great stuff really high build .lasts for about 5 years before needs recoating...

Brushslingers

Normal block filler will roll on and cover about 200 square a gallon, the paint about 300 square with the second coat giving about 400 square. Give yourself some fudge room and theres your amount of paint, always round up. Roller naps and a brush will be about 2 1 1/2 naps, throwaways... 2 brushes and 2 more 3/4 naps for finish, plus drops.

Time-wise, a painter (blue book) crew is three people, they are supposed to be able to cover 1100 square a day finish. I'd stick your guys at about 800 square per day and harp on them about COVER COVER COVER. You should at least break even.

New block needs to be blockfilled before painting. IMO It makes it look much better. Another thing is to let the mortar set for at least 28 days to cure before painting. Ever see a building where the paint is bonding to the block and falling or seperated off the masonry? Its because the ph is to high, if you must paint faster use loxon or xim to prime then blockfill it then paint with acrylic paint of choice.

Hey a post dissappeared. Someone posted a sherwin williams product called sherlastic. I found it on the SW website but I couldn't figure out if this stuff was filler or the final topcoat. Anyone know?

Final topcoat. Its an elastomeric product. Sprays a little heavier than say superpaint. Only to be used if there is no water problems from say roof caps or interior water problems. As i said is will not allow water to penetrate.

Sorry, another thing i dont believe you can get it in dark colors, and cost around 20 a gallon.

I believe your sqare foot coverage with block filler will be about 100 to 135 sq. feet per gallon. Remember trying to stretch the block filler will only create a less than desirable finish coat.

One other thing that works well for thinning blockfiller. No Water. But adding 1 gallon of promar 400 to 5 gallons block fill works wonders.

The block wall should dry at least a month.Rub the wall down with a stone to smooth block.I would spray block filler on and back roll with a 18 inch roller. Price not sure in your area have fun.
