Sealed Concrete Floor NYC

Sealed Concrete brings out the beauty of a surface by enhancing the color and adding sheen. A Floor Sealer will beautify and preserve your floor. Sealing Concrete also preserve the decorative treatment by protecting the floor surface from abrasions and stains. Some industrial floor sealers form a protective film on the surface of the floor, while others penetrate into the floor.

No decorative concrete floor installation is complete without a Sealer application. Adding a color hardener you can get a different concrete design of the decorative floor. Taking the time to put down this final layer of protection not only prolongs the life of your floor but can also enhance and preserve its appearance.

A Concrete Sealing finish is a floor that is ground to a smooth finish and sealed clear. A variety of different water repellent sealers and coatings can be used to finish the floor including Acrylic Sealer, Polyurethane Sealer, and Epoxy Sealer.

Sealed Concrete or Polished?

This is what makes it a sealed floor rather than a high gloss Polished Surface. Some sealers are specially formulated to prevent moisture intrusion under finished floors, and often times sealed floor is used for cheap, low traffic areas.

The problem with sealers is that they are susceptible to damage by moisture coming up through the slab and wear out quickly under heavy traffic on the surface. Each time something passes over the surface it will erode the surface until the sealer is gone and concrete back to the bare slab. Especially in high traffic pathways, routes, or high-impact areas.

These surfaces are prone to needing resealing or re-waxing regularly and never have the same clarity as polished concrete floors.

Concrete Sealer

While polished floors may also use sealers. Sealed Surface differs in that the floor is not honed and polished to the same level of sheen and finish as a polished floor.

A sealed finish is usually a 120 grit finish vs a polished finish at 800 grit. Because less grinding during the polishing process is involved, concrete grind and seal can often be more economical than the polished floor.

Customers may elect to have their portland cement garage floor to any grit level to achieve their desired sheen and finish. Solvent-based sealers can help prevent freeze-thaw issues in cold areas and are used often for exterior purposes.

Or on the CMU walls of your house’s basement in the river bottom, but as an interior surface for high traffic, they just don’t cut it.  They also aren’t as good for the environment as they have higher VOC’s and require much more physical material and maintenance than a burnished concrete surface.

The slip resistance effect could be achieved by adding an aluminum anti-skid powder to the polyurethane sealer.

The life expectancy of the sealer depends on exposure conditions and how well the polished floor is maintained. In general, epoxies and urethanes deliver the best long-term performance and can last years before the need for reapplication. When it comes to Floor Sealer, you get what you pay for. Avoid the temptation to pinch pennies. You don’t want a protective sealer that will wear off after a year or so.

Compatibility with Finishes

Most sealers work on acid-stained floors. If it is the interior and odor is an issue, water-based acrylic sealer maintained with floor wax is fine. If it is a commercial hotel, epoxy with polyurethane would be the system to use. When it comes to a stamped slab, we are using either water-based or solvent-based acrylics. Also, methyl methacrylate (MMA) sealers designed specifically for this application.

The choice of sealer for the stamped surface may depend on the pattern — does the customer want a wet look or something closer to natural stone? For a wet look, the higher the solids content, the greater the gloss. Solvent-based acrylics, 100 percent solid epoxy, gloss polyurethanes, and polyaspartics – all provide what is referred to as the wet look, darkening the concrete color and providing a high sheen.

For a natural stone look, choose a film-forming coating that has a matte or flat finish. You could also use a fully penetrating sealer that will leave the natural look of the surface unchanged.

Protecting Your Investment

In order for the sealer to provide the best appearance and long-lasting protection, it must be applied properly and maintained regularly. Even when applied properly, sealers must be maintained and surfaces resealed. Most of the time customers think the color is fading on their decorative surface when all that is happening is that the sealer is breaking down and needs to be redone. If the project is outside, then the final sealer coat is the wear coat, the sacrificial coat. Plan to inspect the sealer every six months and reapply each year.

Indoors, we recommend applying a floor finish or wax on top of the sealer. Again, this final topcoat is the sacrificial coat. Sealers are no such thing as a maintenance-free floor.
