- Q.I’ve heard
that an adhesive caulk does not bond as strongly as
glue. Is an adhesive caulk like Phenoseal strong enough
to attach a kitchen backsplash to
drywall?
A.Normally, an
adhesive caulk wouldn’t be as strong as
glue, but they are really intended for different
purposes. Glue should be used in cases where two
surfaces can be brought into intimate contact and
held there under pressure for an extended amount of
time. Often, this just isn’t possible on
the job site. Thus, the reason for adhesive caulks
and mastic adhesives: They have a gap-filling
ability not available with traditional yellow or
white glue.
Adhesive caulk should certainly be strong enough
to adhere a backsplash to drywall. The limiting
factor is really the strength of the drywall.
