Yes, you can seal old concrete, but proper preparation is essential. Before sealing, ensure the concrete is clean, dry, and free of any old sealant. To check if resealing is necessary, place a few drops of water on the surface; if they are absorbed in less than five minutes, it's time to reseal. If you are using the same type of sealer that was previously applied, you may not need to remove the old layer. However, if you are applying a different type of sealer, the existing one must be removed. Additionally, repair or fill any cracks to create a smooth base before you begin sealing.
The cost to seal concrete is around $1,500 on average, but you could spend anywhere from $1,000 to $7,000, depending on the type of sealer used and the size of the space. You may want to seal concrete that receives a large amount of foot traffic or heavy wear. While you can seal concrete yourself with materials from a home improvement store, you must ensure the surface is clean and ready to accept the sealer. Hiring a professional is often recommended to ensure good, even coverage that provides adequate protection.
It costs between $600 and $8,400 to stain an average-size concrete patio of around 300 square feet. The wide price range accounts for intricate stains that incorporate multiple colors and stenciling, high-end sealers, and special touches, such as stamping or concrete polishing. Prices can also vary if you need to make multiple repairs to your patio before adding the stain and seal.
If it's well maintained, a polished concrete floor can add value to your home. Concrete is a low-maintenance and durable material that can appeal to homebuyers, especially if they prefer industrial and modern designs. Naturally, higher quality floors will add more value.
The best way to resurface a concrete porch is to clean and prep the surface, pour a layer of concrete on top, allow it to cure, then seal it. A concrete overlay provides a durable layer and enhances your porch's look. You can even choose a stamped overlay to make it look like stone or brick. To ensure structural integrity, repair concrete cracks before applying the new concrete. If the existing concrete is in significant disrepair, consider removing and replacing the concrete instead of an overlay.
