wild idea to cure cement and clean and dry,prime with masonry paint, then...cut a sponge in the shape of a brick,glue to the back of a fitted piece of plywood and attach a knob to the plywood itself. dip in a chicago brick color and then stary imprinting the chicago brick color paint to the grey base masonry paint. when it dries then i want to seal it with a masonry clear seal covering. my idea is to mix masonry sand to the grey paint, and the chicago brown paint to prevent slipping. this is to be done on my patio.this is just a wild idea and i want to know your opinion. today is sunday and i want to get started, please respond immediately if you can. thanks a million.
