It bubbled off the polycarbonate. I guess that's the part I'm not understan=
ding. Isn't silicone supposed to stick well to polycarbonate? They were cle=
an. I'd just pulled the plastic off when I installed last fall.
Thanks.
Q. What type of sealant should be used on sheets?
A. Only use a =E2=80=9C100% silicone=E2=80=9D sealant on polycarbonate shee=
ts. Silicone sealants do not degrade in sunlight. They resist mold and mild=
ew and remain flexible, allowing for building movement. Do not use roofing =
caulk. Consequences of using incompatible sealant are inadequate adhesion, =
too rigid of a bond, and/or the product contains chemicals that may discolo=
r or damage the polycarbonate sheet. Check the product information on the s=
ealant label BEFORE using to ensure compatibility.

A good answer will require good information. Is the wood painted/primed? Is it siding, OSB, plywood, framing material, etc.?
Is it continuously wet? Is this an interior or exterior application? Is it both?
Did you get your surfaces prepped perfectly clean before sealing?
"My caulk isn't sticking" is too vague.

You pretty well need a urethane adhesive like is used to install
automotive windsheilds.

A friend had a cold windy ride home from somewhere between Thunder
Bay and Kitchener Ontario when the replacement window he installed on
his Pelican aircraft blew out on route because he cheaped out and
siliconed a piece of polycarbonate in place instead of using the
recommended urethane adhesive.

Silicone doesn't stick to policarbonate very well.Particularly if it
is not PERFECTLY clean.
