i'm fully aware of most of the adhesives/sealants available for joining laminate worktops, high modulus silicone, colorfill, pva, etc, however i am interested in any well informed opinions concerning bushboard complete and polyurethane sealant (as sold by toolstation). i've been told by someone in the industry that polyurethane is the dogs b******s. is this true and how good is bushboard complete. i'm a joiner with 32 years of experience if this helps. thanks.
