Zip liquid flash ONLY for foundation to sill plate
I have searched and read many threads on the discussion of using sill seal/owen foam/EPDM gaskets + some type of sealant/liquid flashing between foundation and the sill plate. But I can’t find a discussion on skipping the sill seal equivalent material and JUST using a liquid flash, which would obviously achieve the air sealing.
My contractor wants to use zip liquid flash only and skip the gasket. Is that a good idea? or do I need both?
He said he can either just apply liquid flash to the outside connection after the plate is on, or put the liquid flash between the plate and the concrete (and presumably also liquid flash the outside after). Can liquid flash replace the “solid” gasket used in this way?
