    • Why is Traz 25 banned in NY? Traz 25 A is more expensive, I need 10 gallons and would save a $100

      New York has a low VOC requirement,  so the A, which is an alternate solvent,  is required.

    • Thank you for your response where I can proceed with a second coat with Traz-25A seal , eliminating the cure function of spray-cure + seal 25A. So now , what are my options for application? Also, what are your best expectations for proper surface preparation , Please advise...Ray

      You will need to make sure the surface is clean and dry.   If you can pressure wash it,  you will be in great shape.   For application,  you can use a sprayer or roller.

    • I used ChemMasters spray-cure + seal 25A on new cement floor 2 years ago (Garage) ......customer info. on 5 gallon container suggests 2nd application after this 2 year period....Do you carry the spray + cure 25 A ? If not, can I apply the C. M. Traz 25A as the 2nd coat in it's place?

      You shouldnt need the cure function of the previous sealer, so the Traz-25A should work great for your purposes!
