The 14 Best Concrete Waterproofing Sealer 2024 (Reviews & Guide)

Concrete in itself is not waterproof. However, you can waterproof your concrete to protect it from harsh environmental conditions. Sealing of concrete is a maintenance routine that should be done throughout the lifetime of the concrete. This is because it creates a barrier that allows trapped vapor to escape and also repels water. Not just this, it also increases the durability of your concrete. So the question then changes from can you waterproof your concrete to what is the best concrete waterproofing sealer?

Types Of Concrete Sealer?

There are primarily two kinds of sealers. They are the penetrating sealer and the film-forming sealer.

Penetrating Sealer

Penetrating sealers fills the concrete and form a chemical barrier around it. It is also referred to as the impregnating concrete sealer. This is because it soaks into the concrete to keep water out. Siloxanes and silanes are the most common substances used to make penetrating sealers. On the upside, penetrating sealers last longer and do not change concrete’s appearance. On the downside, they are slightly more expensive.

Penetrating sealers are of two types: Solvent and water-based sealers. The solvent-based sealers have higher volatile organic compounds (VOC) and have more sheen compared to the water-based sealers.

Solvent-based Concrete Sealers

This type of concrete sealer is mostly used for the outdoor concrete surface to protect the surface. They do not exist as separate particles but are mixed with polymer for a clear solution. When the solvent evaporates from the sealer, the polymer chain gets closer until they become intertwined. A solvent-based sealer often results in a glossier finish.

Water-based Concrete Sealer

This type of sealer comes with a low VOC and a low sheen. However, unlike the solvent-based sealer, the polymer particles in a water-based sealer disperse and reunite when the sealer is applied to the concrete surface. So as the water evaporates, the particles bond together to form a continuous coating.

Film-Forming Sealer

A layer of acrylic or epoxy protects the concrete surface, and it gives a high-gloss and wet finish. Unlike the penetrating sealers, the film-forming sealers wear out faster. It forms a thin and protective film on your concrete’s surface and is available in solvent-and water-based formulations.
