Went to Lowe's (I know, should have gone to a paint store) and asked
for caulk for my new (hardei plank) outside siding. They advised me
to buy GE "Window & Door" 100% Silicone Sealant. After having applied
5 tubes of this stuff around all window trim, door trim, hardie plank
edges etc. etc., I find that paint does not stick to silicone. Did
not know that!!! I've painted the caulked seams 6 times already and
the paint just retracts from the silicone in about 5-10 seconds.

I can live with the above on all the vertical trim seams, but, on the
butt joints of the hardie plank, in the middle of the wall, the white
blotches look pretty ridiculous.

Any advise appreciated. You're welcome to call me a fool etc., but
please advise.

Thanks,

First thing I would have tried and have always wondered is what RichK
said.

...but you could try putting small cover of paintable on the
top of what you have and paint that.



But Rick Blaine said

silicone caulk does not stick to itself very well


Might try a polyurethane that is paintable over the silicone. It's a
crapshoot. Cost you $5-6 to find out.

Another I've used is Henry 900 Construction & Flashing Sealant
http://www.henry.com/Patching_Repair_Cements.175.0.html
* Superior adhesion for roofing, flashing and construction
applications
* Most flexible and durable sealant available
* Paintable


Both I've painted over fine but never tried it over silicone. Best I can
give ya.
