This water-based sealer helps protect from water seepage, mold and mildew, efflorescence, cracking, sun-damage, salt degradation, chemical exposure and more, all while being extremely easy to apply.Our policy lasts 30 days. Ghostshield has accordingly manufactured a water-based silane/siloxane-based sealer in the form of Siloxa-Tek 8500, abiding by EPA law while selling a product that provides excellent protection with a low VOC content. While chemical solvent-based sealers abound, they are increasingly becoming banned in states such as California, which require water-based sealers. If you are looking for the most advanced concrete sealer for concrete blocks that is environmentally friendly and easy to apply,Siloxa-Tek 8500 is by far the best option available on the market today. As the barrier is actually below the surface, it cannot crack, peel, fade away, or yellow over time, ensuring that your brick looks beautiful regardless of actual age. A silane/siloxane-based sealer is a far better option for sealing concrete blocks its blend of large and small particles, designed specifically for porous material, penetrate the surface and chemically react below the substrate to form a water-repellent barrier. Therefore, a less uniform substance is needed for proper protection. A sodium silicate sealer is comprised of similarly sized particles that seep into the concrete to protect the material, preventing such problems as the spread of mold and radon while helping proof the concrete from water seepage.Ĭoncrete blocks, however, are a much more porous material, featuring small holes and air bubbles of many different sizes. Excellent sealers for low-porosity materials such as a sodium silicate-based sealer simply would not work effectively on concrete block. However, while concrete blocks are largely made from concrete, they are similar to brick in that you cannot seal them as you would a typical poured concrete structure. The best way to prevent this type of problem is by sealing your concrete blocks. Because they are so porous, water easily finds it way underneath the surface, sitting in the numerous air pockets to fester and eventually spawn mold, mildew, and other issues. One of the biggest drawbacks to concrete blocks is their perceptibility to moisture and water seepage. However, if you have an older building, you likely have a basement constructed primarily with concrete blocks. Once the typical material used in basements, newer homes and buildings are increasingly built with poured concrete. Building with concrete blocks has become less and less popular over the past few years.
