Waterproofing solution (Sider-Proof FF)

We renovated a historic building in North Georgia that is 115 years old. The exterior brick and mortar had become very porous and was allowing extensive water intrusion that caused leaks all over the building. The previous owners worked for around 40 years to fix the problem without success -- in fact we had to strip away four layers of other waterproofing products to get back down to the original brick surface. We used your Sider-Proof FF product as the new waterproof coating and the product went up quickly and easily in two coats. I was amazed at how hard the coating cured and how well it bonded to this old brick wall. The coating has completely solved the water intrusion problem and we're all dry now! We've already had two rains since it was installed and NO water penetration at all! Doug - Canton, GA
