I'm looking for a quality robust sealant between rubber bathroom flooring and sanitary ware as well as gap filling between floor and skirting, it's not a wet room but needs to go off hardish and be easy to clean. Does CT1 fit the bill?
I would say yes BUT do a test patch and leave for at least 24h. Ct1 and similar do not like bituminous or latex rubber products. Can you check installation docs for the flooring?
