Pavement Painting: Seeking Advice on DIY Mix

[Silex7]

Pavement paint, pleasezz help

Hello Guys,

well, we -people here in my district in Egypt- are planning to clean the districts and doing some paints to the pavements in streets in order to relief their colors and paints, we are trying to prepare an easy ''home made'' chemical mix in order to paint the pavement( black and white) but i need to know what chemical contents I can get in order to do this job? ..i know about limestone paint, but it is not a good water resistant..any suggestions?

Thanks in Advance,

Use titanium oxide in a latex rubber or acrylic binder for the white. Substitute carbon black for the titanium oxide in the black paint. Small glass beads put on top of the wet paint will make it reflective at night. I would ask someone at BASF for an application using one of their acrylic latexes. They might even give you a starting formula for your needs. You want a solvent that will evaporate relatively quickly, like methanol, or you will get shiny, slick paints. You will need to mix in some very fine sand (if you can find any :) ) to counteract the slickness. You might find that you need to add a small amount of a slower evaporating solvent like Texanol (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate) to act as a coalescing agent for the latex. Texanol is the "go to" solvent in this regard for latexes. I'd also add a UV stabilizer as well unless I was adding crazy amounts of sand or titania. If you need to control sag (the tendency of the paint to spread before it "sets"), I would add Cab-O-Sil. There is a variety that has a silane coating that mixes well with polymers and one that isn't. I wouldn't use the silane coated one if the latex is largely water-based. If the acrylic resin you choose is too brittle you might want to add a bit of rubber latex that is compatible. I would look at the KRATOX line of rubber latex products.

Formulating paints is tough. Street paints are particularly so. It's going to be a real project. Good luck!

Thanks for your precious help my friend, awesome as usual chemisttree :)

Titanium oxide is a good idea (as the white colour now is our big issue), but it is a little bet expensive also carcinogenic, but i will look forward trying this one.
I just contacted BASF Eg. and i am waiting for their response (hopefully).

thanks for the glass beads idea didnt know about this :)
i think ''Butanol'' would do the job as the Texanol, right?

i will write down the sugested additions you wrote but let me remind you, it all depends-unfortunately- on what is available and what is not!

Thanks really for your help, I really appreciate it.
