Considering following the advice on pinterest to replace 1/4 of the water in some concrete with latex house paint to tint it.

Wondering if anyone has done this and knows if this will actually affect the strength or durability of the concrete. Or, as pinterest suggests, improve the concrete.

Yes, there is a similar question on DIY but it was asked if it can be done, and that answer is yes; I'm asking how the resulting concrete will be affected.

    This is largely unanswerable, as it depends on the composition of the paint. While there is a pretty good range of latex concrete additives, each of them has a different purpose and effect on the set of the chemistry of the concrete. Likewise, different paint formulations will have different effects. My recommendation would be to use a latex additive if you need one, and a dye or stain for color. – Comintern May 27 '15 at 0:12
  • Thanks, that makes sense that it's really an unknown. I see a youtube video in the future by some DIYer where he/she replaces 1/4 of the water in some basic cements with standard BEHR paints from Home Depot and shows the results. – ssaltman May 27 '15 at 17:18

There are specific concrete color additives. I would use those. Not paint.

  • thank you but that does not answer the question – ssaltman May 28 '15 at 19:52

Yes you can. 20-60% of the water can be replaced by acrylic paint. Often result is stronger http://www.hms.civil.uminho.pt/ibmac/2008/14IBMAC_123.pdf
