Smartseal - Block Magic is a coloured block paving sealer, which will either change or restore the colour of your block paving. It's comprised of a blend of acrylic resins & liquid pigments which soak deep into paving completely renovating and adding protection to block paving patios and driveways. Everyday weather like sun and rain is one of the main culprits for loss of colouration on block paving, alongside pressure washing and vehicle usage. This is where Block Magic comes in, and works to replace that colour that has been lost.
