If your one goal is to waterproof the basement floor against the transfer of moisture from below, then a simple concrete sealer is a quick, cheap way to get the job done. As a bonus, some basement concrete floor sealers are formulated to resist the transfer of radon through the concrete into your home.

What it is: Most concrete sealers are acrylic liquids that flow easily to make installation a breeze. Your local home improvement store will have a range of products such as EnduraSeal Semi Gloss sealer and Foundation Armor Basement Wall & Floor sealer. Each has a wet look when dry, and these products resist yellowing with age.

How it is installed: Sealers are applied with a large paint roller. For the best adhesion and performance of the paint, it is recommended that you clean the concrete first. Using an acid etch to open the surface of the concrete to improve absorption of the paint helps too. Products like Seal-Krete Clean N Etch handle both of these functions. Most cleaners are applied and then scrubbed into the surface to maximize their performance.

How much it costs on average: The most affordable way to buy a waterproof basement floor sealer is in a 5-gallon bucket. The average cost is $20-$30 per gallon, and each gallon will cover 150-200 square feet depending on how absorbent your concrete is. That comes to just $0.10-$0.20 per square foot.

Concrete cleaning products like Seal-Krete Clean N Etch cost $20-$30 per gallon with similar coverage to epoxy paint.

Most kits contain tint and/or flakes, but both tints and flakes are available for sale independently too. Flooring contractors install epoxy waterproof flooring too at a cost of $5.50-$10.25 per square foot.
