How to Seal Concrete Surfaces

Concrete is a very versatile material that can be used in many applications. It is most commonly used for driveways, sidewalks, porches, and patios. It can also be used for retaining walls, landscape edging, and other areas of construction. Concrete can last a very long time if it is maintained and protected from the elements. Unprotected concrete, especially in northern areas, can be subjected to freeze and thaw damage during the colder months. This most commonly causes cracking, chipping, and heaving of the concrete

Ideally, you want to maintain the nice level clean surface that the concrete was when it was new. To stop any damaging effects it is important to maintain the concrete in several ways. First the concrete needs to be cleaned periodically. This will remove such contaminants such as dirt, grime, mold and mildew, which can cause discoloration and attract and hold damaging moisture. In between cleaning maintenance, about every couple of years, the concrete should be sealed. This will help to waterproof the concrete so moisture cannot penetrate the surface. Sealing concrete is a great way to prevent freeze and thaw damage.

Why Seal Concrete Driveways

Many homeowners today are looking for ways to increase the longevity of their property and exterior surfaces.

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)

Ease of Application: 10

– We applied the MasonrySaver Heavy Duty Water Repellent to a 1000 sq. foot driveway using a plastic pump sprayer. The sealer goes on milky white and dried clear in about 20 minutes. It took less then 30 minutes to seal the entire driveway.

Water Repellency: 8

– We waited a day after application then did a water test. The water did bead up well and did not penetrate into the concrete.

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

SuperSeal M Concrete Water Repellent  Scores (1-10)

Ease of Application: 10

– The SuperSeal M was applied to a new concrete driveway the day after installation. SuperSeal specifically says that the sealer can be applied to new concrete as soon as the bead water is gone from the install. We used 5 gallons for 1000 sq. feet. 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.

Behr Premium Waterproofer Review

Behr Concrete Waterproofer

Behr Concrete Waterproofer

A premium interior/exterior waterproofing formula that uses the latest water-based silicone technology designed to penetrate surfaces up to 1/2″. This waterproofer creates a barrier inside the surface that keeps water out, but lets trapped water vapors escape; reducing corrosion, spalling, efflorescence and freeze-thaw damage. It reduces staining due to mold, mildew, algae growth and ensures greater durability of the surface. The protection is not worn away with normal use. It protects long after the water beading is gone!

Concrete Sealer Ingredients: Silicon

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

Behr Premium Waterproofer Scores (1-10)

Ease of Application: 7

– The Behr Premium Waterproofer is very thin in consistency and looks like you are applying white water. The issue we had is that the sprayer kept getting clogged from large white chunks in the sealer. After running the sealer through a screen, we did not have any more issues. Very frustrating though!

Water Repellency: 7

– After a few days, we tested the Behr Premium Waterproofer with a hose. Light saturation on the water beaded well. Heavy saturation and the sealer did not repel the water very well.

H&C Gloss Concrete Sealer Review

H&C Clear Gloss Sealer

H&C Clear Gloss Sealer

H&C Concrete Sealer Clear Gloss Oil-based is a solvent-based sealer formulated with a silicone acrylic resin.  H&C’s Concrete Sealer Clear Gloss is a 23% solids high gloss coating for virtually any outdoor application.  It seals and protects while providing a durable non-yellowing finish.  It can be used as a decorative glaze on masonry walls, brick, and other cementitious materials.

Tested on Stamped Concrete and Brick Pavers

H&C Gloss Concrete Sealer Scores (1-10)

Wet Look: 5

– H&C Gloss did a poor to average job of darkening brick pavers. It performed slightly better for the stamped concrete over the brick pavers but sill not nearly as good as the other solvent based acrylic sealers.

Gloss Level: 7.5

– Not bad for the gloss level. H&C Gloss concrete sealer contains 23% solid acrylic. This is an average amount for solvent based sealers. One coat showed little to no gloss but the second coat did make a difference and we ended up with a stain sheen to the pavers and a semi-gloss for the stamped 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
