Sealers are a great way to improve the curb appeal of your home and protect your concrete from stains
Overlays are good around pools & patios especially where heat may be an issue.
They are also great for the repair of damaged or spalling concrete
SSealers are a great way to add distinction, value and curb appeal to your home. There are also benefits to sealers, such as resistance to staining and freeze-thaw.
There are many types of sealers available today:
~ Solvent Acrylic
With so many sealers available on the market, it is hard to decide what to use in your current situation. We are going to cover as many of these products and their benefits as we can on this page.
- Eopxy. This can go on very thick for build, crystal clear or colored, with amazing durability and chemical resistance. The downfall of these products are that they have no UV Stability which means when outside or exposed to the sun they will amber, yellow, and fail. Epoxy is the best choice for interior applications with hard wear, such as warehouses with heavy machinery, mechanic shops, and anywhere extreme conditions may be possible.
- Polyurethane. This is another product that can be applied crystal clear or colored, depending on your needs, and also has an amazing chemical resistance and durability. Unlike Epoxy, Urethane does have a UV Stabilizer that allows them to be installed outside in direct exposure to the sun. The downfalls to Polyurethane are cost, and after 48 hrs they will no longer re-emulsify (go from solid to liquid state). When it comes time for a re-coat, the only way to get adhesion is by sanding to create a mechanical adhesion between layers. These products are ideal for use on driveways, walkways, patios, and more.
- Solvent Acrylic, These products come in many forms with different resins, strengths and additives. They are clear and very user friendly, as they are a dip and roll product without a catalyst, which means they don’t require sanding between maintenance coats. Their chemical resistance is not quite as strong as urethane but the cost, ease of use and maintenance makes them the choice product for most installers and homeowners. They are not UV Stable but there are versions made from resins that resist yellowing and ambering for outdoor use. These products are prime for exterior use such as driveways, entryways, sidewalks, patios, and more.
When to Reseal?
Some signs of needing a re-coat are:
~ Yellow or Ambering
~ Less resistance to stains or marking

Cleaning should only be done with a deck brush and water or low power pressure washer. Efflorescence is another problem we may experience in areas with hard water. which is identified when start to see white appearing in puddle areas of our concrete; the key to protecting the sealer against this is cleaning. If you notice a white buildup forming, use white vinegar or TSP (Tri-Sodium Phosphate), scrub the area and allow to sit for 10 minutes before rinsing.
Overlays are an amazing way to freshen up or repair your existing concrete. They can be used around pool decks as a non slip and temperature reducer, on your patio or driveway to repair spalling, cracked, and repaired concrete.
There are many overlays available and numerous manufacturers, but the most common are:
There are so many uses and different versions available for these products that your installer will need to assess the situation and decide the best course of action for your job.
Overlays are very difficult to install and require a high level of training and experience to obtain a quality finish, and should only be installed by a trained professional.
MaintenanceMaintaining your overlay is easy. Keep clean with water and a scrub brush or a low power pressure washer, and be sure to perform regular maintenance on your sealer.
Efflorescence is a problem in overlays too, as they are protected with a sealer. This is identified when we start to see white appearing in puddle areas of the concrete; the key to protecting the sealer against this is cleaning, if you notice a white buildup forming use white vinegar or TSP (Tri-Sodium Phosphate, scrub the area and allow to sit for 10 minutes before rinsing.
