Yes, sealing the concrete around a pool is generally a good idea and is commonly recommended. Pool decks are exposed to various elements, such as water, sunlight, pool chemicals, and foot traffic, which can lead to wear and tear over time. Sealing the concrete can provide several benefits:
Protection against water damage: Pool decks are frequently exposed to water, which can penetrate the concrete and cause issues like cracks, spalling (flaking), and freeze-thaw damage in colder climates. Sealing creates a protective barrier that reduces water absorption, helping to prevent these problems.
UV protection: Sunlight can cause concrete to fade and degrade over time. A quality sealer with UV inhibitors helps shield the concrete from the sun's harmful rays, preserving its appearance and structural integrity.
Stain resistance: Pool decks are prone to staining from pool chemicals, spilled beverages, and other substances. Sealing the concrete makes it more resistant to stains, making it easier to clean and maintain.
Enhancing appearance: Concrete sealers often provide a glossy or satin finish, enhancing the overall look of the pool deck by giving it a fresh and clean appearance.
Easier maintenance: Sealed concrete is easier to clean, as it prevents dirt, grime, and algae from penetrating the surface. Regular maintenance becomes more manageable with a sealed pool deck.
When choosing a concrete sealer, consider the specific needs of your pool deck and the type of sealer that best suits your preferences. There are various types of concrete sealers, including acrylic, penetrating, and epoxy-based sealers, each with different characteristics and applications. Be sure to follow the manufacturer's instructions for proper application and reapplication, as sealers will wear off over time and may need to be reapplied every few years, depending on the type and quality of the sealer used and the level of usage the pool deck receives.
