I am sorry to say that after 10 years and about 3 million sf of pavers sealed with Seal N Lock, I’m am no longer comfortable using the product. Recent changes in their furmulation make it so I can’t get the look customers want and their delays in providing product make it hard to plan and keep to my busy schedule. We will be using either UreSeal H2O or Deco BES paver sealers as our sealer of choice depending on the situation. Both brands have been used by many other contractors who are quite happy with the results. As always I will stand by my guarantee. I will keep my options open for the day they can assure me the product is as good as it used to be.
