Default sealant for Hardieplank

Can anyone recommend a paintable sealant (by brand name) for the end edges where Hardie lap siding butts against wood? Problem with OSI Quad is it takes 7 days to cure. I need something that will be ready to paint within at most a 5 day lift rental.

Frankly I'm having trouble translating this into what to buy:

  • For best results use an Elastomeric Joint Sealant complying with ASTM C920 Grade NS, Class 25 or higher or a Latex Joint Sealant complying with ASTM C834. Caulking/Sealant must be applied in accordance with the caulking/sealant manufacturer’s written instructions or ASTM C1193.

Beachguy's recommendation is very practical. I would suggest a higher grade version which is elastomeric and cures overnight:

DAP Dynaflex 230 (comes in colors)

Yes and I just noticed I pasted paraphrased caulk specs. Hardie's actual statement includes the words "permanently flexible".

Hence the term "elastomeric" ...

Thanks for the help all. Much appreciated. The DAP Dynaflex 230 is readily available at Home Depot and looks like the perfect solution.
