Waterproofing can help your masonry walls perform better. In a perfectly constructed new wall system with proper flashing and perfect joints, waterproofing would not be needed -- But in reality there is seldom a perfectly constructed wall. A rehabilitated wall benefits greatly from waterproofing, as rehabilitation techniques never produce a 100% waterproof wall. Think of masonry waterproofing as insurance, you sleep better knowing that it is there.
It is essential that a transparent waterproofing product allow the masonry to "breathe". Most modern waterproofing products do allow the masonry to breathe, if they are properly applied according to manufacturer instructions. The manufacturer also described acceptable surface conditions for application. Any needed repairs, tuck pointing, flashing, and caulking should be done before any waterproofing material is applied.
