Thompsons ONE COAT Patio & Block Paving Seal - 5L

The water-based formula dries to the touch in approximately 1 hour. However, full curing and resistance to traffic (especially for driveways) takes up to 24 hours.

While primarily formulated for natural stone and block paving, it may be suitable for concrete. Always test in an inconspicuous area first to confirm compatibility and desired appearance.

The durability depends on environmental factors and wear. Reapplication may be needed every few years, or when the water-repellent properties visibly diminish.

Clean spills as soon as possible. Regular cleaning can be done with water and a mild detergent. Avoid abrasive cleaners or high-pressure washing that could damage the seal.

It is generally recommended to remove any old or failing sealant before applying a new coat. Applying over an incompatible or degraded sealant may lead to adhesion issues or an unsatisfactory finish.

The sealer dries to a natural matt appearance, enhancing the paving without significantly altering its color. However, it is crucial to test in an inconspicuous area as results can vary based on the specific stone or block type.

Ensure the product was applied evenly and that no areas were missed or over-applied. Check for consistent application technique.

Verify that the temperature was within the recommended range during application and that there was no rain. Ensure adequate ventilation if applied indoors or in a confined space.

This can sometimes occur if applied too thickly or in very humid conditions. Try a light re-coat or consult the manufacturer's specific advice for resolving haziness.

Allow the product to fully cure (up to 24-48 hours for maximum performance). Re-test water repellency after the full curing period.
