October

In preparing to install a new floor over the existing concrete we must ensure protection from rising damp with a damp proof membrane. I tried Black Jack DMP paint, a couple of coats.  A great idea, to make a neat and thin, sealed surface and edging.

It did not dry.  Even after a couple of weeks, well ventilated, and the weather wasn’t that cold.

Put anything down on it (i.e. anywhere on the entire ground floor of the house) and it gets tar like rubber paint stuck to it, which will not clean off, even with clean spirit.  When you pick the thing up, the painted floor surface is left marked, damaging the damp proof seal.

When you walk on it, same thing.  Paint stuck to your boots, which then sticks to whatever floor you walk on next, staining that.

Nightmare.

In the end I had to put down a plastic sheet dpm anyway to cover the sticky paint, and some very large wooden boards, to cover the floor, so we could crack on with a rewire.

No, I would not recommend this product.
