However, concrete requires maintenance over time. Concrete is very porous, which means that it tends to suck up water, liquids, or any other material it comes into contact with. The exposure to water, ultra violet rays, chemicals, and wear and tear can damage the concrete and the presence of water can also cause the growth of mold and mildew that can damage the structural integrity of your home in the long run. This is why it is extremely important to seal concrete.
You can preserve the new concrete in your home by using the high quality sealant. In our comprehensive guide, we will do a deep dive into what makes the best concrete sealers, types of sealers and their functions, and uses of a sealer, which will help you choose the right concrete sealer for your project.

New concrete is easily damaged - water penetrates into the pores of the concrete, taking along with it, dirt and other debris. This not only makes it difficult to clean the concrete but also reduces the life of the concrete, which is why concrete sealing and choosing the right product to seal concrete is very important.
To preserve your concrete, it is recommended that you use a concrete sealer. Concrete sealers applied to the surface help to protect it from staining, surface damage, and corrosion.
Concrete sealers are chemical compounds that offer an additional layer of protection for concrete and other structures by either forming an impenetrable layer that prevents water and salts from passing through the concrete or by blocking the pores in the concrete surface, thereby reducing the absorption of these materials.
Sealing concrete has several advantages. It helps to protect the concrete from staining, oil spills, and harmful ultra violet rays of the sun. The sealer helps to lock out moisture and prevent any moisture damage, which in turn will help to make the material stronger and more durable. Concrete sealers can help increase the longevity of the concrete and also preserve the color and shine of the concrete.
Most importantly, using a sealant helps to prevent the growth of mold and mildew. In short, sealing concrete can help in many things such as protecting the concrete from stains, cracks, weather damage, and deicing salts.
As we have already discussed, sealing concrete has several advantages and it will protect the concrete from various types of damage. Using concrete sealers to seal old or new concrete is a good idea and the process of curing the concrete and sealing it will not only help to protect the concrete but also help to enhance its appearance.
So, whether it is a concrete patio, driveway, sidewalk, or pool deck, sealing these surfaces can benefit them greatly. However, choosing the right kind of concrete sealer for a specific application can be quite challenging.
For instance, if you have got your concrete floor acid-stained and you want a scratch-resistant concrete sealer that offers durability and will also enhance the color of your floor or if your patio has a stamped concrete floor and you want to know which sealer will protect it best from freeze-thaw cycles—knowing the various types of sealers, what each compound can do, and how you can pick the right one for your project can help you make the right choice easier.
As we already know, there are many different types of concrete sealants and it can be quite confusing to pick the best concrete sealer that is ideal for your concrete areas. Here is a general description of some of the most common compounds and let us look at each of them in greater detail:
Concrete is commonly used in building structures and as you already know, concrete is very porous and absorbs liquids easily. Oil, grease, salt, household chemicals, fertilizers, etc. can discolor unsealed concrete and damage it. Also, freezing and thawing can cause frozen liquids to expand and destroy unsealed concrete.
It is a good idea to seal all the concrete structures in your home by using a good concrete sealer.
Concrete sealers, when applied to concrete, helps to protect the concrete from staining, corrosion, and damage. Concrete sealers either block the capillaries in the concrete to prevent the absorption of water, chemicals. and salt or they form an impervious layer that prevents these materials from passing through the concrete.
Concrete sealers not only protect the concrete surface from wear and damage but also enhance the color and shine of the concrete. Whether it is your patio, stamped pool deck, paver driveway, exposed aggregate walkway, an acid-stained floor outside your home, or any concrete areas such as concrete floors or countertops inside your home, the best concrete sealer will extend the service life and keep your surfaces looking spectacular for several years to come.
And if any concrete starts showing signs of wear after years of exposure to the elements and traffic, you can restore its original beauty with a coat of high-quality sealer.
Once the cement mixture is poured, the most delicate part of the process is the curing of concrete. The poured mixture must sit for a specific period before it hardens fully. Constant temperature and moisture levels must be maintained. If the moisture is too less, then the concrete will get too dry and crumble and if the moisture is too much, then the concrete will crack and this is not very good in the future. So, the curing of concrete is a vital part before it sealed.
Usually, concrete takes around 30 days to cure completely before you can walk on it, use it, or uncover it without causing harm to its strength. This is the same reason why concrete sealers cannot be applied to a concrete surface before the 30-day curing period. If the concrete is not fully cured and you apply the sealer to it, then it can harm the potential strength of the concrete. However, if the sealer is applied once the process of curing is complete, then the concrete will be strong, durable, and protected through its lifetime.
Sealing concrete may or may not change its appearance and all of it depends on the kind of concrete sealer you use. Most of the penetrating or chemically reactive sealers are almost invisible because they enter into the pores of the concrete. On the other hand, solvent-based epoxies and acrylic resin sealers provide the concrete with significant color improvement and give the concrete a wet and high-gloss look.
Acrylic resin concrete sealers of the water-based variety enhance the color of the concrete surface moderately and provide a satiny appearance. Polyurethane concrete sealers, which are usually applied over epoxy as a topcoat, are available in a range of finishes, ranging from a gloss to a matte finish. There are many sealers that are colored with opaque as well as transparent tints.
The quantity of sealer you need depends on several factors such as the type of sealer you are using, the type of concrete surface you are sealing, and the number of coats you will be applying.
As you already know, penetrating sealers penetrate the concrete and offer protection inside out. They do not form a film on the surface and also do not provide any enhancement. However, penetrating sealers are long-lasting. They are watery in terms of consistency and because their viscosity is close to water, penetrating sealers can cover between 100 and 400 square feet per gallon.
Usually, two coats of concrete sealer are recommended and so, for two coats, you can get a coverage of around 50 to 200 square feet per gallon.
Epoxy and polyurethane sealers or coatings have a thicker viscosity and so, their coverage rate depends on the mils (1/1000th of an inch) thickness of application. Some of the sealers or coatings are applied around 20 mils thickness and are considered a high-build system, while other coatings are applied at around 5 mils thickness, which is considered to be thin-build systems.
From a gallon of durable coating/sealer, you can get around 100 to 600 square feet. Usually, a coat of primer and topcoat are applied.
Usually, decorative concrete sealers and coatings are applied in one coat and the amount of sealer depends on the porosity, type of cement, and if the concrete has been sealed previously. For instance, concrete pavers are more porous compared to hand-troweled concrete and will require more square feet per gallon of sealer.
Also, if the concrete has never been sealed before, it will be very porous and will need additional coats. Typically, decorative sealers can cover between 100 and 400 square feet per gallon.
A good tip to save money is that it may be more economical and cost-effective to buy 5-gallon pails rather than buying five 1-gallon pails. This can be quite handy if you run out and need to do some resealing later on.
The time that the sealant takes to dry depends on various factors. The most important factor is the kind of concrete sealer used. Different compounds work and react differently and also take different times to dry. Let us look at the drying times of various concrete sealers:
How long a product will last depends on several factors and you should first determine the type of sealer being used in order to determine its longevity.
Water, stains, cracks, and erosion can cause your concrete to deteriorate and concrete sealers offer protection not only for concrete but also for a wide range of other surfaces like cement, natural stone, granite, and wood. If you are looking for a way to reduce the repair costs in your home, then it is a good idea to invest in a professional-grade, high-quality concrete sealer.
Investing in a high-quality concrete sealer is the ideal way to maintain your interior as well as exterior concrete without breaking the bank.
Until you apply a coat of sealer, your concrete driveways, floors, patios, walkways, pool decks, pavers, countertops, sinks, etc. will not be fully protected from wear and tear. Not only does a high-quality sealer ensure that your concrete lasts longer but also it helps to enhance and preserve the appearance of these structures. In this way, you can add more durability and value to your home.
As you already know, there is a wide variety of concrete sealers on the market and it is important that you buy the best sealant for your specific project. For instance, while penetrating sealers are the best to strengthen and protect concrete, if you are looking for a sealer that will add gloss and shine to the concrete, then buying a topical concrete sealer may be a better option.
In conclusion, any concrete structure is incomplete without sealing and this protective layer is worth all your time and effort in preserving your concrete for years to come.
