Thread 2947848

I have a butt joint with some holes on some fascia boards and I am wondering whats my best material to patch it with
>durhams wood puddy
>bondo
>paintable caulk
Its a 2 story bay miter (turret roof) and the gutter seam was leaking and caused the rot.
And I know your getting exited to tell me to replace the boards, but no thanks , the whole turret overhang section has a gutter on it (and has a higher side connected thats 3 stories )and the customer doesnt want to pay for that much labor
I just figured I would get some patching advice before I get some Wood puddy to experiement wkth

Not Durham's. It is great stuff but it not intended for wet locations. Their FAQ specifically says not to use it where it gets wet.

Same with "bondo" unless you seal the shit out of it. That's basically impossible if you are using it on wood as moisture can travel trough the wood. Now, there is Bondo brand wood filler, which is not the same stuff you use on cars, which should work well.

Caulk will work but you should really use a wood filler that is designed for outdoor applications.

Movement in the boards will cause things to crack.
I’d use butylene caulk. It’s designed to seal joints in eaves troughs.

any bondo
it will never get wet, that's what the paint is for.
best part about bondo is that it's ready to sand a 30 mins

Anything im missing?
Maybe huff the bondo?

Bondo is great for patching. It has some toughness and is mostly hard and sandable. It adhears to the surround surfaces well. It's exterior rated and paintable. The working time is low once you mix it. The only difference I get from the "wood filler" bondo is that it dries tan from a different hardener. But then you sand away too much and it's the wrong grey color again. I buy the big tub from auto stores if I'm going to use it several times all year.

I use mostly Vulkem and Osi Quad. They're both pretty tough exterior caulking.

bondo is ready to sand in 5 desu. Sometimes it dries before I can spread all of a bigger batch.

>vulken and OSI
Yeah i should of taken a photo to see if you think OSI would of been suitable for my scenario

It depends on how much you need, but I have found wood putty epoxy by J-B Weld (KwikWood), or another brand that makes a similar product AquaMend (Quikwood) or yet another one Abatron (WoodEpox) to work much better than Bondo. IIRC Bondo is polystyrene based two part epoxy, and the above products, at least the first two, are of a polymer base that is better than polystyrene and more durable and structural. Frankly, for the final smoothing layer I'd probably still use Bondo before sanding and painting though. And make sure you apply at least 2-3 layers of paint.

plug bigger holes with wood and glue
