Hello Everyone,
I am painting my garage using sandtex ultra smooth masonry wall. I bought 2 x 10ltr tubs.
Problem I have is the walls are concrete blocks with holes so it has pebbles. After 2 coats I can’t fill the wall at the back of garage which is quite rough and many holes.
Is there anyway I can make it smoother to cover these holes? Any techniques I can use? I have a masonry roller and brush.

I applied the first 2 coats using a sprayer which I don’t have anymore.
