    skim coat over vermiculite

    I need to repair a damaged vermiculite base and wondered if it would be ok to level it out with a skim coat of portland and sand? And if it is ok should I use a 3:1 mix or 8:1 mix?

    It is best to repair with vermiculite/poolcrete. You want to match the existing material, or get at least close. Trying to mix materials, vermiculite and concrete, will lead to problems down the line.

    Thanks, I'll use the vermiculite mix. Just so much easier troweling sand and portland.
