I would appreciate anyone who can give me
some help on this one:
How does one go about hardening and
strengthening a layer of concrete that has already been cast and cured, without
removing the concrete entirely? In other words, is there a product that
can be added to the surface of the concrete to harden it?
The concrete in this particular case would
be difficult to remove because of embedded piping. The hardened surface
would then have tile set on it, and would form the floor of a hot water wading
pool. The layer of concrete which needs to be hardened was poured over 2
months ago, and is quite sandy in color with hardly any hint of gray. This
would seem to me to indicate a low cement content.
