How you seal a concrete driveway will depend on the concrete driveway sealer used. If you still have questions about sealing your concrete driveway, or which sealer to use, please contact us at 866-306-0246 for help with product selection or application.

Step 1: Clean The Concrete Driveway

Clean Concrete DrivewayThe first step to sealing any concrete or masonry surface is to make sure the surface is free of paints, stains, sealers, efflorescence, mold or mildew, and any other factors that could potentially prevent a sealer from penetrating or a coating from bonding. We suggest cleaning the surfaces with products like the Armor Efflorescence Remover or the Armor Concrete Cleaner. A cleaning solution in conjunction with a "HOT WATER" pressure washer will bring your concrete or masonry surfaces back to a "like-new" state.  

If you already have a sealer on your concrete, you may have to slightly alter how you clean it. For example, if your driveway currently has a solvent or water based acrylic on the surface, you will want to clean the surface with a pressure washer, and repair any areas of the sealer that appear damaged (white spots, bubbles, peeling).

Once the concrete has been cleaned, it is important to make sure the concrete is allowed to dry completely before applying any type of sealer to the surface. On average, it takes 24-48 hours for a pressure washed surface to dry.

Step 2: Choose a Concrete Driveway Sealer

There are a few types of sealers that can be used to seal a concrete driveway. The best driveway sealer will depend on your reason for sealing. 

Densifiers: Densifiers are used to increase the surface strength and density of the concrete. They can only be applied to unsealed concrete, and they will work entirely below the surface without changing the look or color. If you have concerns about the strength of your concrete, or are having issues with deterioration caused by a weak surface, a densifier is a great place to start. If a densifier is used, you should also consider applying a water repellent sealer, like the Armor SX5000, 5-7 days later. While densifiers increase the surface strength, they don't repel water and water is a leading caused of damage and deterioration to concrete. Water repellents are also clear sealers, but they work to reduce water absorption by up to 95% for up to 10 years. They do not leave behind a visible film or coating, and they will work within the surface to reduce damage caused by water absorption, such as staining, cracking, spalling, mold and mildew growth, and efflorescence. 

Water Repellent Driveway Sealer

Water Repellent Sealers: Water repellent sealers are the most popular type of driveway sealer if you are looking for a 

sealer that will protect the surface without changing the look. The most popular water repellent sealers are the Armor SX5000 (solvent based) and the Armor SX5000 WB (water based). Water repellent sealers offer several benefits. The first
benefit is that they cause water and other liquids to bead off the surface reducing a variety of issues including cracking, spalling, pitting, staining, ice and salt damage, and the growth of mold and mildew. They won't change the look or color of the concrete and will provide years of service life before they start to deterioration. Water repellent sealers can be applied alone, over densifiers, or prior to applying a wet look or high gloss sealers. The benefit to using a water repellent sealer before a wet look or high gloss sealers is that water repellent sealers, like the Armor SX5000, will reduce the movement of moisture through a concrete surface. Wet look and high gloss sealers most often fail from exposure to moisture so by applying the SX5000 first, you extend the life of the wet look or high gloss sealer.

High Gloss Concrete Driveway SealerWet Look and High Gloss Sealers: Wet look and high gloss sealers will enhance the appearance of the concrete and leave behind a visible, protective surface film. They are acrylic based sealers and can be applied in clear or color options. Acrylic sealers are great to use if you want to change the look or color of your concrete, or if you want a protective film that will completely protect the surface of the concrete. They are easy to apply with a roller or sprayer.

Armor AR350: Solvent based wet look sealer that darkens the surface of the driveway and leaves behind a satin to low gloss finish.

Armor AR500: Solvent based high gloss sealer that darkens the surface of the driveway and leaves behind a high gloss finish. 

Step 3: Maintain the Driveway Sealer

The maintenance of a sealer will depend on the type of sealer used and the brand. Foundation Armor products are professional grade and use a higher quality resin and solvent in their formulations. They are designed to provide years of life and performance.

Densifiers: There is no maintenance with a densifier. Densifiers, like the Armor S2000 and Armor L3000, need only to be applied once because the CSH formed within the pores is permanent. While it isn't required, it is suggested to also apply a water repellent sealer, like the Armor SX5000, to protect the surface from the damaging effects of water absorption.

Water Repellent Sealers: Water repellent sealers, like the Armor SX5000 and SX5000 WB, are low maintenance products. While the "bead" may dissapear within the first 6 months to 2 years, the product will continue to work within the pores for roughly up to 10 years. The life of the sealers will ultimately depend on the application surface, the porosity of the application surface, how many coats were applied and how, and how hard the sealer needs to work. When you feel it is time to reapply the SX5000 series products there is nothing to remove - you simply clean the concrete and put more down.

Wet Look and High Gloss Sealers: Wet look and high gloss sealers like the Armor AR350 and Armor AR500 need to be maintained every few years because the gloss starts to reduce in high traffic areas. Most people recoat the surface every 2-5 years. If you are applying a new coat to a coating that is in fairly good shape, you simply clean the surface and put more down. If the coating experienced blushing, or is worn in most areas, use the Armor Blush Repair to re-open the recoat window and apply a fresh coat 4-24 hours later.
