Sealing your concrete protects it from stains, oil, dirt, water damage, and other contaminants. It protects the concrete from environmental conditions and extends its durability. A good concrete waterproof deck coating will make your patio, deck, floor, or driveway keep the aesthetics and looking beautiful. Even in wear and tear condition, the best concrete waterproof sealer will restore its original spectacular look.

Since concrete is mostly the main choice for commercial and residential properties, it is important to maintain its look for years. Garage, basement, floors, pool decks, and patio must be properly sealed for durability and functionality.

So, what are the best concrete waterproof sealers available? What makes a good waterproof deck coating? Concrete sealers are categorized into two: film-forming sealer and penetrating sealer.

Film-forming sealer forms a thin protective film to protect your concrete’s surface. Commonly referred to as topical concrete sealers, film-forming sealers include urethane, epoxy, and acrylics.

Film-coating sealers can be solvent-based concrete sealer and water-based concrete sealer. Solvent-based is commonly used in outdoor concrete surfaces and gives a glossy finish.

However, film-forming sealer needs to be applied regularly as it is susceptible to wear. For that glossy finish while enhancing the look of your concrete, choose film-forming sealer.

On the other hand, a water-based solvent comes with a low sheen but provides continuous seal and coating when applied to concrete surfaces.

Penetrating sealer gives a natural finish on the outer look of your concrete. Penetrating sealers like silicates, silanes, and siloxanes penetrate into the concrete to create a chemical barrier to protect from water and moisture. These impregnating concrete sealers are the best choice for exterior applications as they do not peel or wear away. It will protect your concrete for a span of years and can be reapplied easily when needed.


Can waterproof deck coating be done DIY?

If you are confident you can do the job, you can do DIY. Although most concrete sealers are applied the same way, it is still best to refer to the instructions that come with the sealer that you are using. To ensure success in your DIY project, always:

Apply two (2) coats for optimum protection
