Gaps in cedar porch column - caulk or filler?


I just had the cedar base of my porch post redone, the previous base had cracked from the previous installers not using the right nails and had tannin bleed.

It looked perfect a couple days ago after they installed it. After looking at it just now I noticed the 4 mitered corners have some small gaps forming.

What should I do about these before I paint? They used Dynaflex 230 caulk on the other areas. Should I use that or wood filler to fill these in before painting? Thanks.

I was thinking about using a waterproof epoxy wood filler to fill it.. Does that make sense in this application?

The Dynaflex is pretty good stuff and i think it will work in this situation. With the wood moving as it is, you need as much flex as possible. I don't think the epoxy will give you the needed flexibility. Generally the epoxies dry very hard.

The one reason I was thinking the epoxy is that it wouldn't dry out over time and also act as a bonding agent to connect the 2 pieces of wood together.

I'm just wondering if I should continue with the Dynaflex 230 for this part two. I guess my fear with caulk is after I paint it I didn't want it easily pulling off the wood. I also wanted the corners to look crisp but maybe I'm overthinking it with the wood epoxy?

Quad OSI, ditch the DAP crap.

They should have used titebond and glued the miters. Gotta love guys that think buying a say and know how to cut a miter makes them a carpenter.

I have a bunch of QUAD from the siding project last year, that's all we used. Hopefully it's as paintable as the DAP is.

I agree with the titebond, the previous base all 4 pieces that made up the base split in the middle so he was probably worried about the pieces splitting again if it's held too tight and has movement.

Re: Gaps in cedar porch column - caulk or filler?


Use your fingers to press the caulk into the crack. There's a method of "gentle, yet firm" push that forces it into the crack without making a gobbed up mess of it all. Keep a wet rag handy in case you do get some caulk where you don't want it. In the end, after you paint it, you won't even know there were any cracks there. P.S. I mixed up Dynaflex and Maxflex. I use Maxflex caulking from SW. Lots of elasticity as well as quick drying.

Thanks. Since the installer used Dynaflex 930 caulk, should I leave that in the spots he used it? Or would you recommend to try and remove some caulk and re-caulk those areas with OSI Quad?

Also, is the goal to fill the ENTIRE void of the gap with caulk? or is it just enough to seal it on the outside (so water doesn't get in)?

You're just fine with the Dynaflex. I've used it with no problems and I use a lot of caulk.

Just enough to seal it. Filling much more than that causes the caulk to just fall into the crack.

Re: Gaps in cedar porch column - caulk or filler?


I'd tape the concrete and along the gap as close to the opening as possible. You want to pack as much in the gap as possible. The last thing you want is a failure in your caulking and a void for moisture to accumulate.

Caulk also needs to be supported. If it is not, then over time it will collapse. I doubt you want to have to do this again next year.

Start at the bottom so that it builds up a nice support base.

Cedar wood absorbs moisture and moves. Even glued, IMO, the crack will open again later, use something flexible as stated. You want the crack at top wide enough for 1/4" backer rod/caulking. Didn't back prime (or bottom edge to stop moisture wicking through concrete during rain) or relief cut the wide cedar boards, or air holes...; https://books.google.com/books?id=fD...page&q&f=false

IMO, that is the least of his worries, being that close to a flower bed and almost certain they did not prime the bottom edges sitting on a giant sponge... the paint will flake/bubble fairly soon as the cedar tries to dry out with no ventilation behind it.
