USING OUTDATED DICOR ROOF COATING

I'm prepping my bare aluminum RV roof for coating with Dicor water base elastomeric primer and roof coating.

When I bought the stuff at camping world no one said a word about shelf life or out dates.
The stuff is now 4 years old. It has never been in freezing temperatures and has mixed up well and looks nice and smooth.

Any of you folks have personal experience with using Dicor Roof Coating that is anything like 4 years old?

If using this material is now an absolute no-no, what would you use instead? The number of choices is quite overwhelming.

  • I have used 3 year old Dicor with no problems. It was in a climate controlled area during storage.
    I would try yours on a small area, wait a few days and see how it cures and holds to the surface.
    If you need to get the surface sealed ASAP (leak?), I would buy new for the peace of mind and get it done.
  • Biggest thing with any outdated sealant or coating is getting it out of the tube or can.

    If it flows like it should and isn't too stiff or cured in the container, it should be ok. You'll know when you open it and go to use the stuff.
  • Guess I always take the other approach.

    I would rather throw away perfectly good sealant than take a chance that it will not flow or worse, not set up.

    Said another way, I value my labor (particularly if it might involve removing a real mess) over the cost of the sealant.
  • Thanks for the input...
    The material mixes well and though the primer seems thinner than the final roof coating, which is markedly thicker but does mix to a consistent smoothness, I suppose the only thing I can do, short of tossing it all out, is try it on a small area and see what happens.
