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.
Do you offer a paving sealer developed specifically for patio paving slabs?
The Smartseal premium paving sealer generally is suitable for patios, but due to the fact that paving slabs have many different levels of porosity, it is always recommended to do a test area first
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.
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.
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 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?
