10 Best Patio Sealer 2025 in the UK

The Sika Patio Seal Paving is a water-based sealer that offers several appealing features for those looking to enhance their outdoor spaces. As a water-based solution, it is non-flammable and has a low odor, making it safer for use around plants and animals, which is an essential consideration for eco-conscious users. The product excels in water repellency, providing a protective layer that reduces dirt pickup and simplifies cleaning with standard detergent, which is ideal for high-traffic areas.

Additionally, it dries to a low sheen finish, which is slip-resistant and can enhance the aesthetic appeal of your paving. Its water and mark resistance can be a significant advantage for keeping your patio looking fresh and clean, preventing unsightly stains and marks. Furthermore, the inclusion of a fungicide helps prevent the growth of fungi on the sealed surfaces, which is beneficial for maintaining cleanliness and preventing discoloration.

While the product is durable and provides UV resistance, users should consider the acrylic base and its long-term effectiveness compared to other types of sealers, especially under intense weather conditions. Some users may prefer a different finish, as the low sheen might not suit everyone’s aesthetic preferences. The ease of application is a plus, but depending on the surface condition, multiple applications might be required to achieve optimal results. The compact size of 5 liters is practical for smaller areas but might not be sufficient for larger projects without purchasing multiple units.

The Smartseal Block Paving Sealer offers a satin 'wet look' finish, enhancing the visual appeal of block paving and patios. Its solvent-based acrylic formulation is designed for durability, providing a reliable protective layer against harsh weather conditions and oil spills. This makes it suitable for outdoor surfaces that need to withstand varying temperatures and potential staining.

The sealer functions as both a sand hardener and weed inhibitor, which can help maintain the integrity and cleanliness of your patio or driveway. This dual functionality is a strong point for those particularly concerned with maintaining a neat and weed-free paved area.

Application is made straightforward through compatibility with sprayers or rollers, covering up to 2 square meters per litre for the first coat, and 3.5 square meters per litre for the second coat. This efficient coverage helps to mitigate the concern of needing more product for larger areas. While the product boasts water repellency, it doesn't explicitly mention UV resistance, which could be a consideration if your paved area is exposed to significant sunlight.
