Big Stretch question

Kevin McGuire | Posted in General Questions on

Can anyone verify if this is true or not…

i just got off off the phone with Sashco and they said because big stretch is a water based caulk and that it is an acrylic latex type of caulk that it will adhere better to pre-painted (acrylic latex paint) fiber cement siding and cedar trim than a quad max type Рpolymer type caulk

    Here are tech sheets on these two products:

    OSI Quad-Max -

    Sashco Big Stretch -

    The properties of the OSI Quad Max seem superior to me, all things considered. In general, in my experience, silane-modified polymer sealants have better performance than water-based elastomer sealants.

    Perhaps not the most useful answer, but I've had excellent experiences with both. I don't think the differences between them are significant enough to matter.
