If you’ve recently had your patio professionally jet-washed or installed a new patio in your garden, and you’re preparing to host a gathering with your close friends, we recommend sealing your new pavers before starting the festivities. By following a few simple steps, you can ensure that your patio is well-protected against the elements. First, thoroughly clean the surface to remove any debris, dirt, or weeds. Allow it to dry completely before applying the sealant, and then allow the sealant to cure for a few days before subjecting it to heavy foot traffic.
Sealing your new patio properly is essential for maintaining its durability, enhancing its appearance, and protecting it from the elements and staining. It’s crucial to choose a high-quality sealer that is suitable for the specific material of your patio pavers. Consult the instructions provided by the manufacturer to determine the number of coats required and the drying time.
Properly applying a sealant to your patio pavers
Effective sealing of your patio pavers is vital for their longevity and appearance. The first and most important step is to thoroughly clean the pavers before starting the sealing process. Any dirt, plant matter, or debris can hinder the sealer’s ability to adhere properly to the stones, resulting in an uneven finish and reduced durability. Power washing is the best method, but hosing down and sweeping with a thick-bristled broom can also suffice.
Whilst wearing protective gloves and eyewear, apply the sealant evenly in layers across the pavers using a sprayer or roller. Allow the sealant to dry before applying a second layer. The second layer is crucial for reinforcing the protective barrier, but it’s important to apply thin coats of the sealant. Ensure that you cover the entire surface and remove any excess sealer. Pay close attention to the joints between the pavers, as the sealant can accumulate in these crevices.
Always follow the drying instructions provided by the manufacturer for the sealant. Even if the sealer claims to dry quickly, it’s best to wait for twenty-four hours before walking on the patio or placing furniture on it. The curing time of the patio pavers can also be influenced by the weather, so choose a warm and dry day. If you live in a humid climate, exercise additional caution.
Sealant options for your garden patio
There are various sealant products available on the market, depending on the material of your patio and the desired look. An acrylic-based sealer provides protection against water damage, sun damage, and stains. It is available in different finishes, such as matte or glossy, and dries completely within an hour of application. Whilst these sealers are more affordable, they require more frequent maintenance, so make sure you are willing to commit to the upkeep.
Another option is a penetrating sealer, which is water-repellent and recommended for preventing mildew and mould. If you have porous patio materials like limestone or slate, a penetrating sealer is the right choice. Both oil-based and water-based options penetrate deep into the stone, providing protection against natural wear and tear and serving as a barrier against the elements.
Film-forming sealers, unlike penetrating sealers, offer a glossy, wet-look finish. For non-porous stone pavers, it is preferable to use a film-forming sealer as it protects against environmental issues like acid rain, grass stains, and salty or sandy soil. Granite and slate are popular choices for patio pavers, and they require careful maintenance to preserve their natural appearance and prevent deterioration. In this case, a film-forming sealer would be the best option.
