    Drylock on exterior cinder block
    Can anyone tell me how effective Drylock is for the exterior of cinder block walls? We are having water issues during heavy rains. Will this stop it?

    Have used Drylok extreme on a 2' block wall. Painted both sides with 2 coats 2 years ago and is still solid.

    The only problem is that water will seek the easiest route in.
    This means that the water will enter where u stop the paint.

    If it is ground water coming up from under slab, this will not stop it.

    Thanks for the answer, that could very well be the problem. The grade on this building is very low in the back.
