They may end up causing cracks or moisture damage if you live in an area with heavy precipitation. The penetrating-resin concrete sealer is much more expensive. For the best results should be applied professionally. The protection provided by penetrating sealers goes, as the term implies, deep within the concrete, creating a chemical barrier that protects against moisture. Many experts agree that concrete flooring should be sealed every years, in order to preserve and protect your floor.
Of course, the amount of time between sealant application can depend on many different circumstances. Only you know how much your floor can endure between applications.
Consider the location and use of your concrete. Our goal with this post is to make sure you have what you need to make informed decisions going forward. Concrete sealers are applied to surfaces for protective purposes. The chemical makeups of sealers provide certain utility and qualities for different concrete surfaces.
Concrete sealers are designed to protect surfaces from internal and external damage. Whether the sealer protects internally or externally is dependent on the type you choose. A concrete sealer is generally sprayed or rolled onto the surface, but the application is dependent on the type of sealer you choose.
The best type of sealer for porous surfaces poured concrete, paver stones, brick is a penetrating siloxane sealer. Perfect Power Wash uses a proprietary siloxane sealer.
Siloxane sealer is a penetrating sealer designed to enter the pores of the concrete and strengthen it from within. Our proprietary sealer helps protect from cracking, chipping, spalling, and pitting caused by the freeze-thaw cycle that concrete in the Midwest is susceptible to. Sealer is used on all types of concrete, but it is not recommended to attempt to seal asphalt. The store will not work correctly in the case when cookies are disabled.
April 18, Technical Information. There are several factors that contribute to how long a concrete sealer actually lasts for, but the life of many types of concrete sealers will fall into a very specific Silicate Concrete Sealers : Silicate concrete sealers never break down.
They spark a chemical reaction in the concrete in order to form a calcium silicate hydrate structure within the pores. Once that structure is formed, it can only be removed if the concrete itself is removed. Silane Siloxane Water Repellent Sealers : Silane-Siloxane water repellent sealers will last anywhere from 6 months to 10 years depending on the quality of Silane-Siloxane sealer used, and the percent solids. Most low solids solutions found in store will last 6 monts to a year, while higher solids solutions, like the Armor SX and SX WB will last for up to years.
Siliconate Water Repellent Sealers : Like with Silane-Siloxane water repellent sealers, Siliconate sealers will last anywhere from 6 months to 10 years. Most low solids solutions found in store will last 6 monts to a year, while higher solids solutions, like the Armor SC25 will last for up to years.
Acrylic Concrete Sealers : Acrylic sealers last years before they need to be re-coated. Epoxy Coatings : Epoxy coatings last years before they need to be re-coated. Urethane Coatings : Urethane coatings last years before they need to be re-coated. Paint: There are too many variables to set an estimate on how long paint will last. Paint will always peel, but it could be years before peeling.
There are several factors that contribute to the actual life of a concrete sealer: The quality of the product applied. There is a large difference in quality from one product to the next. The percent solids, the source of the raw materials, and the actual formula will have a large impact on how well a product performs and how long it lasts. The amount of coats applied. This is actually a very important factor.
Concrete sealers wear off eventually. Penetrating sealers last the longest: up to 10 years, while epoxy and urethane lasts from 5 to 10 years. Acrylic sealers have the shortest lifespan of years.
However, there are methods you can employ to check if the sealer has already worn off. There are many factors that affect the longevity of concrete sealer. Read on to learn about it and more.
It also helps to know which ones last the longest, so that you can save time and money. However, the type of sealer you use will have the biggest influence in how long it lasts. Penetrating sealers are formulated out of resins such as silanes, siloxanes, silicate, and silicone. Just as its name implies, they work by penetrating the concrete and leave a chemical barrier that prevents oil, water, and other contaminants from getting into the surface of the concrete.
These sealers are recommended to protect from stains, particularly in concrete driveways , garages, and foundations. Penetrating concrete sealers can last 5 to 10 years , and they are the longest lasting type of concrete sealer.
Acrylic sealers are recommended for more porous concrete. They stay on the surface and leave a raincoat-like barrier that protects the concrete.
This is because imported recycled resins use chemicals that are derived from the recycling process that causes sealers to break down easily. In addition, water based acrylics are more difficult to maintain and repair because screen sanding is usually required. On the other hand, solvent based acrylics are easier to repair using Xylene, and recoating is as easy as applying a fresh coat to concrete that has been cleaned and dried.
