I am nearly finished with construction of a new shed. I have a few
more trim pieces to cut and install and then I'll need to caulk the
necessary joints. I'm using white PVC for the trim (Versatex) so I
won't have to paint it so I'll need to use white caulk.
I've had some caulk that has yellowed in a relatively short time but I
don't remember what brand that was. Does anyone have any
recommendations for a high quality, non-yellowing caulk?
Something strange is going on with NewsGuy. My original message
appeared after I posted it -- as it should have. I then retrieved the
body with no problem and then marked it to "Watch" this thread.
When I came back to this group just now I couldn't see my original
message or Stormin Mormon's reply but I could find Doug's repeated
plea to Stormin Mormon.
Has anyone had similar problems recently with NewsGuy?
Thanks for the info.
I would NOT recommend any silicone caulk other than Dow Corning 795.
I have been using Titebond for Metal Roofs with very good results. It
is a newer polymer technology, not a silicone or a polyurethane.
The metal roof formula has better adherence than the regular
Weathermaster, adheres well to wet surfaces, sets under water, and cures
to a great bond. Similar price to NP-1.
Keep the whole world singing . . .
Yellowing is due to UV exposure, so contrary to opinion here, acrylics
should do perfectly well since they are inherently UV resistant.
Silicones are also UV proof, but there is a problem later if touch up
painting is needed. Urethanes, can't comment, maybe someone in the
trade has the facts.
