This sand hardener and block paving sealer is easy to apply and effectively inhibits the regrowth of weeds and moss, protecting your block paving and keeping it looking like new for years to come. It creates a durable barrier that guards against oil spills and stains, making it ideal for driveways and patios. For best results, apply it at a ratio that depends on the width of the joints, allowing it to seep 20mm into the joints. This advanced block paving sealer is formulated to the highest BS5750/ISO9001 standard. Protect your investment and enjoy a beautiful, weed-free driveway or patio. Application guidelines: For newly laid block paving, apply as soon as possible. For older block paving, make sure that the surface area is completely cleaned and bone-dry. Pour sealer onto the surface in sections and use a squeegee to spread the sealer and soak it into the sand. Apply the second coat within one to two hours of the first coat. Quantity: 5L. Pack of two.
