I come across this site wile trying to look for information about whether contact adhesive will dissolve or eat away at Silicon and/or hard set and P. S. acrylics if In close proximity to one another. I've seen it done and would like to know for a vinyl cove job coming up. Im thinking IF your using a wet room silicone to secure a caping strip and cove fillet, and using contact adhesive to secure the vinyl cove, the silicone will weaken or loose it's bond from the gas build up of contact adhesive over a short time! I've always just used contact for securing capping and fillet. Can't go wrong that way. But it would be good to reduce the amount of solvents I'm breathing in! I also like the idea of using mapitape for flash cove but I just can't see it working long term! It's a bit of a joke actually. I'd maybe only try it for pre-formed internal and external. Has anyone used or had a problem with wetroom silicone or roof and gutter silicone for for caping? Or used mapitape for coving?
