Best exterior silicon/paint for facade reno
wrkrwood
| Posted in General Discussion on
Hi,
I want to replace and paint the facade surrounding my bay window. The north east weather seems to have caused the seams to split the joints and the paint has blistered, but I have no water damage in the house.
A local lumber yard recommended marine grade ply for the wood, which seems ok.
Ben Moore exterior paints seems to be well appreciated in these forums, but my paint store recommends California Paints. Is that better at 50 per can?
Also, is there a best silicon, industrial grade, that I can use to caulk the seams? Any tricks to keep the seams from separating?
Many thanks in advance.

Don't use Silicone Caulk
OSI makes several paintable caulks (some in several colors) that last.
Urethane caulk is great, tho hard to use.
Silicone caulk (100%) paint won't stick to.
I like MDO plywood for exterior panels. Great paintable surface-comes primed-lasts if you detail it anywhere near right.
What Calvin said.
Don't use silicone caulk - OSI quad is one that I like but that is partially because it is readily available (at blowes). It isn't easy to work with either but a little better than polyeurethane (sp?). You will need to get rid of as much of the old caulk as possible...
Sherman Williams Duration is a good paint but it isn't inexpensive either.
RE the substraight, it might help to hae a pic or something to get us a better idea of what you are repairing. Guys at lumber yards have been very helpfull to me and are good at presenting what they sell but not always the best resource for the best way to do something. You see - they don't warranty your work - or anyone elses... It's kind like the guy at the auto parts store may likely be a very good resource but not necessarily a master mechanic.
Paint won't stick to a silicone sealant. I'm not a big fan of latex caulk with silicone additive. Nothing wrong with it, but there are better products. Personally, I like polyeurethane sealants. Great adhesion, good stretch, great weathering performance. The only draw back is that they attract dirt. This won't be an issue if the surface is painted. Remember, caulk is cheap and sealants are better performing.
1110d: I'm guessing...
your post was ment for the initial poster.
BTW - there are silicone caulks that are specifically made to hold paint. I've used them and they seem OK, but you gotta figure they must not be that great as they have been out for at least 10 years (that I know of) and haven't gained much popularity.

With pure silicone caulks that say "Paintable", you must read the directions. A couple that I've looked at required/suggested almost immediate (few hours) painting.
