What Can We Help You With?

Dependent on the type of block paving laid 2 coats recommended*, then "top up"coats can be applied periodically as required.

As a general rule the appearance of pattern imprinted concrete when damp is how it will look once is it cleaned and a clear paving sealer has been re-applied.

If additional colour is required Smartseal can supply a full range of sealer tints.

Once sealer has been applied the block paving will be far less porous so any further staining will be easily removed. In most cases undiluted washing up liquid will be sufficient. In bad cases we advise the use of Oil Stain Remover available from Smartseal to solve the problem.

If your block paving has sealer applied properly then any future deterioration will be extremely minimal. The acrylic sealer enhances the colour of the block paving, minimises colour loss from ultra violet light, protects against oil stains, weeds and algae growth. It also solidifies the sand in the joints of the block paving which gives further overall protection.

Kiln dried sand is always recommended. This ensures the joints of the block paving are completely filled. This type of sand solidifies and bonds more effectively with the block paving sealer giving maximum protection against weed growth and the future loss of jointing sand.

The life expectancy of paving sealer is generally between 5-7 years but will vary for several reasons - the amount of paving sealer applied, vehicle traffic use, exposure to sunlight and porosity of surface will all be relevant factors. For example, a north facing driveway with limited sunlight exposure will need re-sealing more frequently than one facing south.
