The Prosoco Saltguard, manufactured by Prosoco, is a general-purpose silane/siloxane sealer that promises to resist water and the incursion of harmful salts and chlorides. The Saltguard is actually specifically manufactured and designed to protect your concrete from erosion from salts.
Overexposure to salts and chlorides is especially a problem in places with harsh winters. In the winter, the roads become icy and slippery due to snow and ice. Plow trucks, in addition to plowing away snow, also lay down large quantities of salt in most areas. As your car drives along roads in the winter, the tires pick up a lot of that salt, tracking it back into your driveway and garage. Once here, that salt can melt off with the snow, dripping onto the floor where it can seep into your concrete and cause structural damage.
Salt corrosion can also be a problem in places where the concrete is supported by rebar. The rebar, made of metal, can rust and corrode quickly, gravely threatening your structures. A silane/siloxane sealer like the Saltguard will help lock out that salt from the surface of the concrete. With a mixture of particles of silane and siloxane at work, the concrete will be protected from within and on the surface. The Saltguard can be applied to horizontal surfaces, as well as vertical ones, making it great for floors and walls. Additionally, the Saltguard is a great choice if you live in a coastal area, whether or not you have harsh winters. The salt from the ocean can also corrode your concrete over time, and applications of the Saltguard will help lessen the damage.
