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 vertical surface. So I defer to the experts! Thanks very much for your help! Frank

If you are planning on touching up all exposed foundation, you might want to consider EIFS.
Parex makes a dry powder base coat that will fill and bond to your block foundation. You could skim where necessary and finish with textured or elastomeric finish.
