Elastomeric Waterproofing System is normally used on exterior stucco and often when the surface has a lot of hairline cracks. Elastomerics are formulated to be applied in very thick coats. When applied correctly, due to their high elasticity, they have a special capacity to span hairline cracks permanently. Instead of these cracks reopening on your stucco, the Elastomeric would stretch and keep them sealed up. This then keeps water out and protects your home from damage. Elastomeric looks much like any other paint and it can be tinted to most colors.
