Oil based paint for concrete

We were asked to paint white stop bars at a mobile home park today, they just had it newly seal coated on Saturday. My question is should we use latex paint or will the oil based paint be ok? Thanks, Dan

Latex

Latex, The Oil Base will brown. At least thats the problem we have had....Yellow Oil doesn't do too bad with not browning but White looks horrible over new sealer.

Latex all the way

Alkyd will work if the seal coat mixture is an asphalt derivative. It won't work if the sealer is a coal tar emulsion.

I have had great results with SW Hotline Latex on new sealer. Two coats for Stop Bars. Latex on Coal Tar Sealer. Domingo.

The sealer we usually stripe over is Neyra sealer out of Cincinnati and it is a coal tar sealer so...

A shop just wants some bollards put in old asphalt in front of their shop.I put signs in,but do I need a core drill to drill out the old asphalt.Should I get a steel pipe,paint it and fill it with concrete.I also have some signs coming up that must be in a bollard in concrete.Any advice would be appreciated.

We use 1/4 stell well casings for our bollards. We chop a 1ft square hole with an electric jack hammer. Dig it out with post diggers, drop in the pipe put the post in the pipe and if its not a high hazard area, we have been using pea gravel to fill the pipe and top off with an inch or two of concrete. If that post ever gets broken off all you have to do is chop out the top layer of concrete and shop vac the pea stone out and reuse. The 1/4 steel casing will take a direct hit from a car and not move. A trailer will shear it off with or without concrete. then we fill the hole up with concrete. JIm ps. dont use pvc, I will post sone pics of someone who did.

If they put any good amount of sand in sealer wait as long as you can or get owner to pay you to go back and paint again after tracking has stopped. We painted stop bars in mobile home park and it was black with tracking a few days after doing.And of course latex.. Will thermo work over sealcoating?

Say if I use maybe 6 or 8 inch diameter steel,I guess they are usually about 4 ft tall,and paint yellow,any suggestions of pricing it.I just have never done these before.

What about new concrete? latex too? Thanks, Dan

Should I use Oil based paint for new concrete or latex? Thanks, Dan

I don't know how to price them but you should look at plastic bollard covers - they are maintenance free and don't require re-painting and all the prep that entails after they've been painted numerous times!

either one will work on concrete, if the surface is clean, cured, and has some texture. I always wait 30 days after concrete is poured to give it time to cure. Sooner than that, the paint might peel.

See the post at [url]http://www.pavementpro.com/forum/showpost.php?post/7885/ [/url] for a good response from a coal tar sealer manufacturer. As to the other questions always latex over sealer, you can "get away" with alkyd on AE but it damages the sealer. With coal tar the paint doesn't really "turn brown" but the coal tar does it's job and drives away the solvents and "oils" in the paint bringing them to the surface and making it appear brown. For new concrete it all depends on the concrete. Normally alkyd or CR will work fine, or latex will work fine but depending on the alkaline content of the concrete I have had situations where one peeled up and the other stuck both ways. So it's trial & error. I'd try what you normally use first. If you have problems with the concrete mix normally used in your area try the other. Much like another thread here about new asphalt, the majority of those who post here use alkyd or CR however they have never been a paver like me; for me nothing but latex on new asphalt. That's what The Asphalt Institute says and so do many specifications so better safe...IMHO
