Sealed Concrete Floor – Dustless and Affordable, Enhanced Finish
A sealed concrete floor brings out a surface’s beauty by improving a natural color and adding sheen to an old floor. As any porous surface has to be protected from mechanical abrasions and stains, therefore, using any concrete sealing procedures should be a must to extend a lifetime.
No decorative concrete floor installation is complete without a sealer application. Also, by adding colored stain or dye, 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.
What is the difference between Sealed and Polished Concrete?
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 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.
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.
What is Sealed Concrete Floor?
Sealed Concrete floor is a process when a surface is ground to a smooth finish and sealed clear. Installers can use various water repellent sealers and coatings to finish the floor, including acrylic concrete floor sealer, polyurethane, or screed sealer.
Sealed concrete is usually a 120 grit finish vs. polished 800 grit finish. In fact, the Concrete grinding and sealing process needs fewer grinding passes. Therefore it’s more budget-friendly.
Our customers want to improve their Portland cement garage floor surface to a smoother surface and achieve the desired sheen. Solvent-based sealers can help prevent freeze-thaw issues in cold areas and are used often for exterior purposes. Contractors could achieve the slip resistance effect by adding an aluminum anti-skid powder to the polyurethane sealer.
We have performed millions of square feet of slabs sealing, including indoor floors, outdoor and stamped surfaces, natural stones, and driveways. Utilizing materials such as Clear Acrylic Sealer or Water Based Epoxy, Urethane Clear Coat and, Epoxy Floor Paint, etc.
How Long Do Concrete Sealers last?
If you expect a longer life of the sealer, make sure you choose the right system and maintain it properly. In general, epoxies and urethanes deliver the best long-term performance and can last years before the need for reapplication. When it comes to Concrete Floor Sealer, you get what you pay for.
You can get similar performance using a urethane or epoxy system, which commonly lasts 5 – 10 years, depending on the traffic level. Acrylic Water-based sealers withstand the shortest performance life – around 1 to 3 years.
Sealers Compatibility with Different Finishes
Most sealers work great on acid-stained floors. However, if you have an interior space and an odor, a water-based acrylic sealer with a floor wax works the best. If it is a commercial hotel, epoxy with polyurethane would be the system to use.
When it comes to a stamped slab, we use either water-based or solvent-based acrylics—also, methyl methacrylate (MMA) sealers are designed specifically for this application.
The choice of sealer for the stamped concrete will depend on the customer’s expectation to achieve a wet look. Consider, the higher solids content, the greater the gloss. Different types of liquids will provide this effect:
For a natural stone look, choose a film-forming coating that has a matt or flat finish. You could also use a fully penetrating sealer that will leave the natural look of the surface unchanged.
How to Clean Sealed Concrete Floors?
The best possible application and regular cleaning will guaranty the best appearance and long-lasting protection. A good practice will be resealing the surface after several years of use in high-trafficked areas. Most of the time, customers think the color is fading on their decorative surface when all that is happening is that the sealer breaks down and needs to be redone.
If the project is outside, then the final sealer coat is the sacrificial coat’s wear coat. Plan to inspect the sealer every 6 months and reapply each 1 year. Again, this final topcoat is the sacrificial coat. Sealers are no such thing as a maintenance-free floor. Get in touch with DUOMIT and request your Free Estimate now!
