    • What should I use on a concrete driveway 11years old that was treated with a similar product the day it was installed and was band the next year. I have used seal 25 now band in Michigan? Thanks. Bill

      You can use the alternate solvent version,  Traz-25A 

      Same product, just a low VOC compliant solvent

    • How long does the appearance remain unchanged after the application? I'm looking for something that's resistant to spring thawing and popping off, I'd pay more for a better solution

      My suggestions would depend on the type of finish you're looking for. High gloss etc.  Give us a call at 888-391-2227 and we can discuss.

    • Do you have smaller containers for this poly sealer ez?

      Unfortunately,  we only have the 5 gallon sizes.

      The only difference is the solvent used.   Traz-25A is for use in areas that require low VOC

    • Will you guys ship to Ohio?

      Traz 25 can not ship to Ohio due to VOC restrictions.  However, Traz-25A can ship to Ohio

    • Will this product help with concrete sweating and condensation build-up? I live in Indiana and during the late winter and spring seasons, we experience a lot of condensation on our Barn concrete floor.

      I would suggest a penetrating sealer.  Such as Ghostshield Siloxa-tek-8510.   That coupled with the Lithi-Tek 4500 will help prevent the moisture from coming through the concrete

      Recoat 1

      Heavy Traffic 12

      It is a cure and seal so you can apply it as soon as the bleed water is gone

      Assuming it is clean and dry,  yes

    • Do you ship to Canada or is the product available at a retailer in Canada?
