Aggressively work a medium layer of cement into the fitting ...
Cement
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).
How long does it take for concrete to dry after washing?
When concrete is sealed, it can take up to two weeks for the concrete to fully cure. If your concrete does not cure properly, it will crack or crumble. Drying time will vary depending on several factors, but on average concrete takes between two to ten days to dry after washing. The concrete will continue to dry over the following weeks; the.
