As the popularity of decorative concrete continues to soar, more homeowners are discovering the stunning, affordable elegance it adds to their spaces. However, to keep that beautiful look intact, regular resealing is essential. Many contractors apply a sealer as the final step in the installation process, but ongoing maintenance every few years is necessary to protect your investment. Here’s a simple guide to help you reseal your decorative concrete and keep it looking its best.
Step 1: Choosing The Right Sealer For Your Application
Before you begin, you must know the type of sealer initially applied. Decorative concrete sealers are commonly solvent-based, but new VOC regulations mean some newer sealers are water or acetone-based. Knowing the original sealer type is essential, as water-based sealers don’t adhere well to solvent-based ones, similar to how oil and water-based paints won’t mix.
Deco-Crete D-One Sealer is the most popular choice for homeowners and contractors looking for an all-in-one penetrating sealer that will provide a natural look. If you want a high-gloss finish, consider using Deco-Crete Diamond Shine Sealer. If you want a matte look, Deco-Crete Super Stamp Seal is preferred. These are our most popular sealers; however, we have a large variety of other sealers and additives available for niche applications.
Step 2: Checking The Weather Conditions
Weather conditions are critical to successful sealing. Aim to apply sealer during cooler times, like early morning or evening in the summer, to avoid high temperatures that can cause the sealer to cure too quickly. The ideal temperature range for applying sealer is 60 - 70° F. Also, be sure to check the forecast and avoid sealing if rain is expected, as moisture can cloud the sealer’s finish.
Step 3: Cleaning and Preparing Surface
Thoroughly washing the concrete surface is essential. Move evenly across the surface using a pressure washer, keeping the nozzle about a foot above to avoid damaging the concrete. For stubborn spots, use a mild cleaner and a stiff-bristle brush. Ensuring the surface is free from dirt and debris will help the new sealer bond properly.
Step 4: Applying and Reapplying Your Decorative Concrete Sealer
After cleaning, ensure the surface is completely dry before applying the sealer. Trapped moisture can cause the sealer to look cloudy, so consider using a leaf blower to dry hard-to-reach areas, especially saw cuts. When it’s time to seal, remember that two thin coats are better than one thick coat for an even finish.
Application Methods
Spray: Use a concrete sealer sprayer, like those from Chapin, to apply the sealer evenly in a back-and-forth motion.
Dip and Roll: Pour sealer into a paint tray, dip a ¾” nap paint roller, and roll evenly across the surface. Avoid pressing too hard to prevent roller lines.
Spray and Back Roll: This combines spraying and rolling for optimal coverage. One person sprays a thin coat, while another follows with a roller. Wait 6-12 hours after the first coat before applying the second.
With the right sealer and method, you’ll keep your decorative concrete looking fresh and well-protected for years.
