Review on ๐Ÿ  Sikaflex 715 Roof Sealant by AP Products: Ultimate Waterproofing Solution by Kevin Hutchison

Revainrating 4 out of 5

Restrictions and Surface Preparation

All caps instructions DO NOT APPLY TO EXISTING ROOF SEALANT. I was thinking of using this to seal cracks in old Dicor lap sealant, so I haven't used this Sika 715 (yet). I would like this restriction to be included in the product description. In addition, the instructions refer to the use of a special Sika surface cleaner, which upon further research turns out to be SikaSenseยฎ-3502/11. Unfortunately, this product isn't available and the companies that sell it want an arm and two legs for it. However, many reviewers here and elsewhere say that acetone is an excellent surface cleaner for this overlap sealer. Again, it would be a good idea to include this information in the product description. I am very fond of Sika products, particularly Sikaflex 291 polyurethane sealant. I strongly believe that this 715 overlap sealant works excellently for its intended purpose, but I am deducting a star for the inadequate product description.

Pros
  • Few competitors
Cons
