Hi. The ground floor is concrete overlain with mastic/asphalt. The mastic is about 25mm thick. Obviously, the mastic is providing a waterproof seal. The concrete below will, one expects, get damp - or is liable to.
I've cut out a 500mm x 500mm area of mastic thus exposing the concrete.
But, I won't be overlaying again with mastic. In fact I wish to overlay the concrete with cement. But cement is not a waterproof material.
I presume I can use some kind of special paint, to paint over cement to effect a waterproof seal.
The area will not be walked over.
Can anyone please recommend a particular product?
Only problem I can see is the expense.
