Many homeowners are starting to appreciate the benefits of concrete floors. Their durability, versatility, and cost-effectiveness make them a favored choice in households.
However, an important factor to keep these floors in good condition is by applying a protective coating. Rescrete is here to provide the ultimate guide to concrete floor coatings, so all homeowners can understand the options available, why concrete coatings are necessary, and common mistakes to avoid.
What Are Concrete Floor Coatings?
Concrete floor coatings are protective and decorative layers that shield the concrete from external factors such as moisture, chemicals, stains, and physical wear. Some coatings are purely functional while others offer protection and an attractive appearance.
Why Concrete Floors Need Coatings
Raw concrete is durable, but it is still susceptible to external damage. Untreated surfaces eventually start to crack, chip, and develop stains. Water can seep into unprotected concrete, potentially causing structural issues like mold growth or freezing and thawing damage.
A high-quality concrete coating acts as a barrier between the floor and any external factors. The coatings can reduce moisture accumulation, prevent abrasions, and make the surface much easier to clean. As a result, homeowners who invest in concrete coatings can save money on repairs and replacements over time.
Types of Concrete Floor Coatings
Concrete floor coatings come in many varieties. The right choice ultimately depends on your home’s needs and your design preferences.
• Epoxy coatings are a popular option for their durability and glossy appearance. They are resistant to water, chemicals, and abrasions, making them ideal for spaces including garages, basements, and workshops.
• Polyurethane coatings are flexible and resistant to impact, making them good for areas with heavy foot traffic.
• Acrylic coatings are a cost-effective option that offers easy application and quick drying times. While they may not offer the same level of durability as epoxy or polyurethane, they are ideal for decorative purposes or spaces with light traffic.
Prepare the Concrete
Homeowners should always clean concrete before applying a coating. Imperfections or contaminants can compromise the coating’s adhesion, longevity, and appearance.
Thoroughly clean the floor to remove dirt, grease, or previous coatings. A combination of sweeping, scrubbing, and pressure washing will sufficiently cleanse the surface.
Next, inspect the floor for cracks, uneven spots, and other damage. This is a great time to use a concrete filler or level the surface.
Etching the floor is frequently necessary for non-porous concrete surfaces. The process involves applying a mild acid solution to open the pores of the concrete. It enhances the coating’s ability to bond to the concrete. After etching, rinse the floor and wait for the concrete to dry before continuing the application process.
Apply the Coating
The process of applying a concrete floor coating involves multiple stages. Each layer contributes to the overall performance and appearance of the finished floor.
The first step involves priming the surface. The primer helps the coating bond to the concrete, improving its durability and finish. It can also fill in minor imperfections, like scratches, to create a smooth base.
After the primer dries, apply the base coat. This is the main layer that provides protection and durability to the floor. Each type of coating requires a specific number of primer layers, so check the product’s instructions to determine the best course of action.
You can also lay down a sealant to act as a final layer of protection. The sealant enhances the coating’s resistance to scratches, stains, and UV light, while also increasing the floor’s overall shine.
The last step is the curing process, which allows the layers to completely dry and harden. It can take anywhere from 24 hours to several days depending on the coating type and environmental factors, such as the space’s temperature and humidity.
Choose the Best Finish
Concrete flooring coatings offer customizations, too. Whether you want a matte or glossy finish, bright colors, or a decorative pattern, there’s a coating available to transform your concrete floors.
A metallic epoxy coating is a popular option that provides a luxurious, marbled look to mimic the appearance of flowing liquids. Chip or flake systems are popular for garage floors. They feature small, colorful chips to create a textured finish.
Homeowners may also apply colorful stains or dyes during the coating process to achieve hues that match the interior design. Some coatings can even include anti-slip additives for spaces where safety is a concern, such as bathrooms and pool decks.
Care for Coated Concrete Floors
This ultimate guide to concrete floor coatings isn’t complete without explaining general maintenance practices. Fortunately, concrete floors require minimal maintenance; you can keep them clean without much effort!
Routine cleaning involves sweeping or vacuuming debris and mopping the surface with a mild detergent and water. Avoid strong chemicals or abrasive cleaning tools that can deteriorate the floor’s finish. Another helpful cleaning method is pressure washing outdoor concrete surfaces. This is a great way to remove dirt and grime without needing to mop the floors clean.
Lastly, perform periodic inspections, especially in high-traffic areas. Pay attention to any signs of fading, peeling, or scratches. Reseal the areas, as needed to keep the concrete coating in exceptional condition.
Common Mistakes To Avoid
While concrete floor coatings can dramatically enhance your home, applying them incorrectly can lead to a lot of complications. Here are a few common mistakes homeowners make.
Lack of Surface Preparation
One of the biggest mistakes is skipping surface preparation. Failing to clean, repair, or etch the concrete may result in poor adhesion.
Coating Application During Adverse Weather
You should also avoid applying the coating during extreme weather conditions like high temperatures or humidity. Severe external factors may negatively affect the curing process.
Applying the Wrong Concrete Coating
Using the wrong type of coating for the intended use or traffic level is also a frequent issue. For example, choosing a lightweight acrylic coating for a garage that sees lots of heavy machinery is likely to result in early wear and tear.
