product help

Hi!

a while back I noticed a builder who was about to render a wall, mixed a product into the mix.

It was a milky colour I think, but when it was mixed with water, or just exposed to the air it started to turn a dark purple colour.

I was told it was a damp proofing.

Does any one know what this was and what is called?

sounds like waterproofer there are a few available, sika is one of the top names and one of the most expensive but like a say top name.
