Driveway & Patio Sealing in Grays — 2-Coat Smart Seal, 3–5 Year Minimum
Before any sealer goes down, the block paving is fully cleaned and left for 3–5 days to dry completely — sealing over damp block paving causes the sealer to fail early, which is what happens with DIY jobs that are rushed. Once dry, kiln-dried sand is worked back into every joint before the sealer is applied. Terry uses Smart Seal block paving sealer applied in 2 coats by hand roller — not sprayed. Two coats ensures full coverage and proper penetration. Hand rolling is the manufacturer-specified method for maximum bond and longevity.
Smart Seal penetrates the surface and bonds at a molecular level — it cannot peel or trap moisture, unlike DIY sealers that sit on top and break down. Three finish options are available: natural (no visible colour change), colour enhance (deepens the existing tone), and wet look (full gloss). All maintain slip resistance. Smart Seal prevents oil and salt penetration and keeps kiln-dried sand locked in the joints. Applied correctly with 2 coats over a properly prepared surface, results last a minimum of 3–5 years.
