The lifespan of a sealer depends on a number of factors, including the type of sealer and where it is applied. In general, sealers will last between 3-5 years before needing to be reapplied, but this largely varies from situation to situation.   In order to get the best use out of your paver’s sealant you can ensure that you take preventative measures against ice dams from forming by running a water barrier or ‘ice control membrane’ down first before laying your bricks to do so. Afterward apply a latex pavement primer and contentious solution as indicated on instructions for your brand/style before proceeding with application according to instructions provided by manufacturer – doing so should provide you with an optimal sealant lifespan.   This info was brought to us by The Home Depot.
