How long do you wait after making a concrete slab with the Durham water putty before painting with a floquil aged concrete? I've drawn the lines and scribed them, just not sure how long I have to wait before painting and weathering.
Thanks

I think it depends upon the thickness. I would wait overnight, or simply feel for any dampness. You mentioned Floquil paints, if it's oil based, I would wait overnight, if water based, you could probably proceed when it feels dry. It's pretty tuff stuff. I doubt you'll damage it either way. The packaging doesn't appear to be of any help regarding set up time etc. Just my two cents. Mark
I would not recommend painting it - I weather / color mine with soft pastel chalks - usually after letting it dry overnight. Floquil paints will change the texture and make it look like painted concrete. My cent and 1/2.
Well I'm definitely waiting overnight, John I'm just following the kits directions but I'm a bit leary now to proceed with the floquil aged concrete. John are you referring to the Rembrandt chalks? I'm intrigued with your method.
I have painted it with floquil paints and have not had any problems. I have built forms and done some casting of walls, slabs, footings etc and it has worked fine. I don't remember how long I waited to paint though.
Thanks Steve , I actually poured it last nite but I know what happens if plaster is still holding moisture.

Yes - I'm referring to the Rembrandt chalks but there are a number of good manufactures. Pan Pastels are another soft pastel chalk. The best advice I can give you is try a test sample - I like the chalks because I can get the color and the texture right. If you don't like the color with chalks you can use a soft rubber eraser and remove them and try again. The floquil paint will work but I like the look of the chalks - it's a personal opinion and you may want to give it a try.
Thanks John , I'm quite familiar with the Rembrandt chalks from the Sierra West kits I've done and know what you mean about the textures. I was actually going to be finishing with the chalks.
Lynn, if there are any concerns about the paint disturbing the putty itself, you can hit it will some Dulcote first and create a barrier.
Thanks Craig I never would have thought of that .
