Types Of Sealers
There are two primary types of sealers available: topical and penetrating. A topical sealer sits on top of the concrete and provides a barrier between the concrete and the outside world. Topical sealers, also known as film-forming sealers, are typically acrylic or polyurethane. However, they are less durable than penetrating sealers and must be reapplied more often.
Give the concrete a high glossy shine while forming a protective ﬁlm on the surface, like polyurethane and epoxy. They are economical and easy to apply by spray or roller. These sealants repel water and provide a durable chemical and abrasive-resistant surface.
Sealer is a crucial element in concrete polishing. Sealers work by filling in the microscopic pores in the concrete, which protects the surface from water and other liquids. Several forms of sealers are available on the market, each with advantages and disadvantages.
The sealer you use will depend on the look you are going for and the amount of traffic the floor will see. This article will analyze the different types of sealers available and help you choose what sealer to use on polished concrete.
The Water-Based Sealers range makes very effective polished concrete sealers. Their nano-sized polymers penetrate deep into the substrate and form an acrylic co-polymer matrix throughout the top layers of the concrete. Acrylic sealers provide a high-gloss finish and are available in water- and solvent-based sealers. Acrylic sealers are durable and easy to apply, but they can yellow over time.
One of the best acrylic sealers is Sikagard High Gloss Sealer. It’s water-based and has low VOC content. Sealers with high VOC content can cause headaches, nausea, and organ damage. Unfortunately, solvent-based formulas have a higher VOC content. Limits (Rule 1168) for VOC content do exist but not enough to prevent these effects.
Polyurethane sealers are another type of topical sealer. They also provide a high-gloss finish and are available in both water-based and solvent-based formulas. Polyurethane sealers are more durable than acrylic sealers.
Varathane Water-Based Ultimate Polyurethane sealer gives customers scratch resistance and even dries in 30 minutes. These properties make it ideal for any interior concrete floors.
A penetrating sealer or a concrete densifier penetrates the concrete, forming a barrier within the pores. They typically comprise Siliconate. They provide a more natural finish. They are also more durable than topical sealers and do not need reapplication as often.
In fact, they prevent absorption up to 85 percent, which lasts much longer. However, they can be more challenging to apply and may require professional help.
Siliconate sealers work best on unsealed and uncolored concrete. This sealer repels water which prevents the concrete from breaking down over time. It is a clear sealer, giving your concrete floor a professional yet clean look.
PS101 by Concrete Sealers USA is one of the best Silicate concrete sealers. It works great on floors that attract dust. Once this sealer dries, the floor has protection from cracking, staining, dust, mold, and mildew.
Should You Seal Your Polished Concrete Floors?
Sealing polished concrete is not mandatory. However, it can help to protect the floor from stains and dirt. Sealing also makes it easier to clean the floor. If you decide to seal your floor, you’ll need to reapply the sealer every few years to maintain the protection.
How Do You Seal A Polished Concrete Floor?
Here are some tips to follow before sealing polished concrete.
1) First, you should apply concrete sealer when the temperature is above 50 degrees Fahrenheit, and the humidity is below 80 percent.
2) Before applying the sealer, ensure the floor is clean and dry. If there is any paint on the surface, you should grind it away.
3) Avoid using concrete sealer in direct sunlight. It can cause the sealer to dry too quickly, resulting in an uneven finish. It will also cause the sealant to wear out more rapidly in those areas.
4) Cover windows and doors to prevent sunlight from coming into the room.
5) Also, wear protective clothing to avoid getting the sealer on your skin or your eyes.
6) Remember that a solvent-based sealer or an acrylic sealer will require two coats. A penetrating sealer will only need one coat.
7) Avoid applying too much sealer because it can cause the sealer to pool on the surface of the concrete and form a thick, glossy film. It can make the floor difficult to clean and cause the sealer to peel.
To seal a polished concrete floor, first, clean the floor with a vacuum and broom. Then, apply the sealer to the floor with a roller or brush. Rolling is the best way to apply concrete sealer because it provides even coverage. Spraying also works, but it is more difficult to control the amount of sealer used. Allow the sealer to cure for the recommended time before walking on the floor.
When Should You Not Seal Your Concrete Floors
There are instances when you should not seal concrete. One example is when the concrete is new. Concrete needs to cure for one month before applying sealant.
Another instance when you should not seal concrete is if the floor is in poor condition. If the floor is cracked or damaged, sealing it will not repair it. In fact, sealing a cracked floor can make the problem worse.
If you need clarification about whether or not you should seal your concrete floor, it’s best to consult a professional.
What Is The Difference Between Epoxy and Acrylic Sealers?
Epoxy and sealer are two different products used to protect concrete floors. Epoxy is a resin that cures to form a hard, protective coating that is harder than acrylic. It comes in color options as well. Film-forming sealer is a liquid applied to the floor and dries to form a thin, protective film.
Epoxy is more durable than sealer and is better suited for high-traffic areas. Sealer is less expensive than epoxy and is a good option for low-traffic areas.
