Concrete Sealers - Single Part
There are two main types of concrete sealers - penetrating sealers and surface sealers. They are usually designed to make the concrete water repellent, and may offer protection from chemicals and resistance to staining agents.
Penetrating sealers work by reducing the porosity of the concrete via the delivery of microscopic solids via a solvent. This system generally does not alter the appearance of the substrate, and because it does not sit on the surface of the concrete does not significantly alter the slip resistance of the dry substrate.
Surface sealers are designed to bond tenaciously to the concrete and form a physical barrier between liquids and the substrate. These sealers can make the concrete appear significantly shinier and will reduce the slip resistance of the dry substrate. Slip Resistant additive can be added in suspension when the product is applied.
If you do not want the appearance of the concrete to change, penetrating sealers are likely to produce the best result. Penetrating sealers are more expensive, and it should be noted that in either case, you still need to clean off spills and surface contaminants if you want the surface to appear and remain clean.
