												Does applying the block paving sealer kill all weeds?We cannot guarantee that this will be the case. After the ‘cleaning’ process we suggest applying a ‘weed killer’. After re-sanding, the acrylic block paving sealer will ‘sand bind’ and protect the sanded joints, this will help reduce and make it a lot more difficult for weeds to put down their roots again. But further growth can always occur unless a small amount of general 'upkeep' is maintained* * Please see 'application guide' supplied with block paving sealer.

												Can you restore the original colouring of Pattern Imprinted Concrete?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.

												How long will the paving sealer last once applied?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.

												After my driveway has had block paving sealer applied, how easy is it to clean off new oil and dirty stains?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. 
- 
												What type of sand is swept between the joints in block paving?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.

												Will my block paving or pattern imprinted concrete look shiny once sealer has been applied?As a rule of thumb how the paving looks when damp, is how it will look once treated with sealer. The majority of people feel this gives the paving a 'fresh look' and are very happy that the original colour has been restored.
