What are the major benefits of applying block paving sealer to my driveway?
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.
-
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.
-
How many coats of block paving sealer would you recommend?
Dependent on the type of block paving laid 2 coats recommended*, then "top up"coats can be applied periodically as required.

What kind of driveway or patio cleaning equipment would you recommend?
A standard power washer will do the job, but one with a rotary head* style accessory is recommended for driveway cleaning and patio cleaning. As a general rule, the more powerful the washer, the less time it will take.
-
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.

After researching several products I am confused about sealer coverage ratios, can you help?
Yes, at Smartseal we are always looking to give accurate advice, not just 'sell you some sealer'. With this in mind we recommend a coverage ratio of 2sq metres per litre 1st coat and 3.5sq metres per litre second coat. You can spread it a lot thinner than sometimes stated with other products, but long term you will be dissapointed with the results, so what is the point?
