How to Water Proof Concrete

How to Water Proof Exterior Concrete, Brick and Masonry

When water is able to penetrate concrete, it can cause all sorts of damage. Water and moisture absorption causes concrete to swell, which can lead to pitting, cracking, and heaving. In colder climates, freeze and thaw damage is a major concern. As water gets into the concrete and freezes it expands causing major damage if neglected.

To prevent damage of concrete, the surface should be water proofed. Water proofing concrete creates a water repellent barrier to lock out moisture. This stops all water related damage from occurring. In addition, waterproofing concrete will also prevent spills and stains from penetrating and potentially leaving permanent staining.

Best Sealer for a Garage Floor

Best Garage Floor SealerBest Sealer for a Garage Floor to prevent oil stains and make cleanup easier.

Garage floors can be a pain to keep clean and looking good. Because garage floor concrete is porous, it easily absorbs moisture and stains such as automotive oil and coolant. Once these stains penetrate the concrete, they are hard to remove.

The best sealer for a garage floor will offer resistance to unwanted staining. The best sealer will also keep water and moisture from penetrating the concrete and causing damage. Garage floor sealer application will increase the appearance of the floor and make it easier to maintain. Unwanted fluids and stains can be cleaned up more easily on sealed concrete than concrete that is not protected.

Siloxane Based Concrete Sealers

Siloxane Concrete Sealers

Siloxane Concrete Sealers

Siloxane Based Sealers are Best for Poured Concrete, Brick and all Masonry Surfaces.

Siloxane, not to be confused with Silicone, is a chemical that is used to formulate siloxane based concrete and paver sealers. Siloxane based sealers can be water or solvent based although the water-based blend of siloxane sealers are lower in VOC and more compliant in certain states.

These siloxane sealers are popular among homeowners because they are user friendly and easy to apply. They penetrate into the surface and react to cause a hardened barrier within the substrate pores. They do not stay on top of the surface like other sealers

How to Seal Concrete Driveways

When it comes to protecting your concrete driveway, nothing can be more beneficial to its longevity than a concrete sealer. Concrete sealers provide protection from weather exposure, moisture, oil stains, tannin stains, deicing salts, and will protect from freeze/thaw damage. They enhance the natural beauty of the concrete and make it easier to clean and maintain in the future.

Preparing an existing concrete driveway for a sealer is vitally important. It is best to wash the surface with a pressure washer and a high-quality concrete cleaner. Dirt, mold, mildew, and all unsightly stains should be removed prior to applying a driveway sealer. If there are remnants of an old concrete sealer, it should be removed using a concrete sealer stripper prior to sealing.

MasonrySaver Heavy Duty Water Repellent Review

MasonrySaver Heavy Duty Water Repellent

MasonrySaver Heavy Duty Water Repellent

MasonrySaver® (Also known as “Defy”) All-Purpose Heavy Duty Water Repellent is a modified siloxane based product designed to penetrate deeply into most masonry and concrete pores. Unlike acrylics, silicones, and other waterproofing sealers that remain on the surface and trap water vapors, this masonry waterproofing product allows deep penetration of its active ingredient of up to 1/4 inch or more. This proprietary blend of silanes and siloxanes creates a “SaltShield™” barrier on concrete surfaces, for greater resistances to the deteriorating effects of road salts and de-icing chemicals. This 100% breathable concrete waterproofing product is a great choice for both horizontal and vertical above grade surfaces.

Concrete Sealer Ingredients: Blend of Silanes and Siloxanes

Concrete Sealer Type: Invisible Water Repellent. Does not change appearance.

MasonrySaver Heavy Duty Water Repellent Scores (1-10)

SuperSeal M Concrete Water Repellent Review

SuperSeal M Sealer

SuperSeal M Sealer

SUPER SEAL-M is a water based Silicone Water Repellent made of a special hybrid of Silane and Siloxane. SUPER SEAL-M provides water repellency to porous construction materials such as bricks, stone, concrete blocks, mortar, and grout. It is not suitable for very low-porosity substrates such as polished stone.

The active ingredients in SUPER SEAL-M Water Repellent Sealer are a mixture of different-size particles-some larger, some smaller to fill different size voids. This ensures good penetration into porous substrates, resulting in good coverage and durable water repellency. Additionally, the active ingredients in SUPER SEAL-M Water Repellent can chemically react with the substrate, ensuring long-lasting performance.

Concrete Sealer Ingredients: Blend of Silanes and Siloxanes

Concrete Sealer Type: Penetrating Clear Water Repellent

It took 30 minutes to apply and did not have any issues.

Water Repellency: 8

– After 3 days we tested the water beading with the garden hose. All of the water beaded up on the driveway with a light mist of water. A heavier saturation and the water still did not penetrate into the concrete.

Concrete Sealers and Water Repellents

Concrete Sealers are used to protect and enhance all types of Interior and Exterior concrete surfaces. They can provide water repellency for driveways and brick walls or enhancement for decorative concrete surfaces such as Stamped Patios or Pavers.

In this article, we will look at the many different types of Concrete Sealers, Coatings, and Water Repellents.

Concrete Sealers and Water Repellents

Concrete sealants and water repellents are the most popular of the concrete coatings. These sealers are designed to penetrate deep into the surface without filming on top. They typically do not change the appearance of the surface. These sealers are composed mainly of different types of silicones. Silane, siloxane and silox are the most common forms used. These particles penetrate deep into the concrete, reacting with the alkali. This creates an internal bond that seals out water, dirt, grime, and common spills. These sealers work exceptionally well and do come in different solids amounts ranging from 8-24%. Higher solids are typically for very porous block while lower solids are for smoother concrete surfaces.

Available in both water based and solvent based formulas.

Pros: Very easy to apply. Typically last 4-6 years for most applications.

Cons: None
