10 Best Paver Sealers 2025 in the UK

The Sika Patio Seal Paving is a water-based sealer designed to enhance the appearance and protect paving surfaces. It is a great option for those who want a non-flammable and low-odor sealer that is safe for plants and animals. The product is water-repellent and provides a slip-resistant, low sheen finish, making it suitable for areas that are frequently exposed to moisture. Its milky solution dries to a hard-wearing film that resists dirt and marks, simplifying cleaning. The inclusion of fungicide helps prevent unsightly growths, extending the product's durability.

The acrylic-based formula is applied easily, making it accessible even for those with limited DIY experience. With a drying time that isn't specified, users might need to test it themselves. Its 5-liter packaging is convenient for covering medium-sized areas without needing frequent repurchases. However, some might find its compact size a limitation for larger projects.

Rated 4.3 out of 5 stars by over 2,600 users, it is a popular choice, ranked highly in its category. While the product dimensions and weight suggest it is easy to store and handle, it might still feel a bit heavy at 5 kg. Its water- and mark-resistance are excellent features, especially for new or recently cleaned paving, but users should be prepared for possible variations in effectiveness based on the surface conditions. For those looking for an effective, environmentally sensitive solution for patio sealing, it stands out as a reliable option.

The SmartSeal Eco-Friendly Block Paving Sealer is a solvent-free, durable sealer designed specifically for block paved driveways and patios. It offers a natural, colourless finish that protects surfaces by hardening joint sand and preventing weed growth, making it ideal if you want to maintain a clean and natural look. Its high-performance, hard-wearing formula resists oil stains and tough weather conditions like rain, heat, and frost, helping to keep your paving looking fresh over time.

Application is straightforward with a squeegee or sprayer, and the coverage rate is quite efficient—about 1.5-2 square metres per litre for the first coat and up to 4 square metres per litre for the second coat. This means you won’t need a huge amount of product to cover larger areas, making it cost-effective. Because it’s solvent-free, SmartSeal is safer for the environment and easier to handle, but it is meant only for concrete-based block paving, not other materials. Some users might find the 25-litre container heavy to manage, but that’s typical for this product size.

If you want a reliable sealer that balances eco-friendliness with strong protection and prevents weeds while keeping your paving natural-looking, SmartSeal is a solid choice. Just be prepared to allow enough time for it to dry thoroughly before walking or driving on the sealed area.

The Marl Coatings WET LOOK Driveway Block Paving Sealer is designed to give your block paving a glossy, wet appearance that many find attractive. It creates a clear protective layer that helps repel water, reducing stains and damage caused by weather and daily use. This sealer improves the durability of your paving by guarding against wear, oil stains, and dirt, making cleaning easier. It’s a resin-based, white spirit sealer suitable for block paving and resin surfaces.

Applying it is straightforward—whether you use a brush, roller, or sprayer—which makes it accessible for both professional and DIY users. It dries relatively quickly, usually within 2 to 4 hours at 20°C, allowing you to get your driveway back in use without long wait times. The product comes in a large 20L container, which is quite heavy at 20 kg, so be prepared for that if you plan to move it frequently. While it offers good water resistance, it’s not fully waterproof, so very wet conditions might require reapplication over time.

With a solid customer rating of 4.3 out of 5 stars, many users praise its effectiveness and finish. This sealer is a good choice if you want a practical, long-lasting solution to protect and enhance the look of your block paving with minimal fuss.
