Big Stretch question
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 – polymer type caulk

Here are tech sheets on these two products:
OSI Quad-Max - http://www.ositough.com/content/dam/uac/osi/master/PDFs/TDS/tds-quad-max.pdf
Sashco Big Stretch - https://www.sashco.com/hi/pdfs/BigStretch_TechData.pdf
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.

Kevin,
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.
