One of the worst aesthetic problems that can afflict concrete is staining. While structurally not a problem, stains can permanently mar the surface of your concrete, offering a nasty visual blemish that will plague your home forever. Whether oil stains on your garage floor, wine stains on your concrete countertops, or stains from fallen leaves marring your outdoor concrete, you want to protect your concrete from stains before they happen.
A concrete sealer offers the best level of protection for your concrete, helping prevent stains from seeping into the concrete. The best product is a penetrating sealer, like Siloxa-Tek 8505 or Siloxa-Tek 8510. The 8505 is water based while the 8510 is solvent based. They are both natural finish products that are silane/siloxanes with fluro polymers to resist staining from oils, grease and leaves. It will also lock out surface spills and materials from entering into the concrete, ensuring the spills remain pooled on the surface for easy clean-up.
