The cinder block foundation on my summer home is eroded in the
vicinity of a downspout. There are holes which need to be patched,
and it is necessary to get a smooth vertical surface (for finishing)
over some areas that are several inches in diameter and recessed
by about 1".
What is the best product to use, sand mix or mortar? I would
like to use sand mix for strength, but because mortar sticks better
I would think it would be more suitable for building a finished
So I defer to the experts!
Thanks very much for your help!
