Behr Ultra Exterior Paint after 4.5ish years

[The Critic]

This was painted in 11/2021. House faces west.

At the time this was new wood siding. I primed, then painted 2 coats of Behr Ultra. Possibly 3.

Seems premature for 4.5ish years. Thoughts?

Paint can only do so much if the wood is not dimensionally stable. If the paint is the real problem then I think the cracks would likely not look all along the grains.

The T1-11 siding on my shed looks the same using Pittsburg. There's no preventing it. Thank the sun for the cracks.

It is the siding. Does that get a bunch of direct sun?

@PandaBear bear nailed it, wood is not dimensionally stable, T1-11, Cedar, pine, etc, you name it. The paint adhered perfectly to the wood, the wood cracked. If a paint company were to send a rep out to check that job out for paint failure, they'd tell you the paint didn't fail, the wood cracked. The problem is wood harvested today for construction is young wood that was planted to replace trees used to supply wood for construction. It tends to crack, split, twist, and rot, very early. Ever go to HD and look for a good straight 2x3, or 2x4? LOL it's a chore!!! Yes some lumberyards have wood that's a little better than the big players, but not by much. Bottom all the good well aged trees have been harvested many decades ago.

I've repaired a lot of premium high quality wooden windows made by well respected compaines in multi-million dollar homes, that were properly primed and painted that rotted after about 15-20 years, some quite a bit less.

Yes

We only side with hardy or LP these days. Modern wood is low quality, an engineered product is necessary imo.

Yeah, that's not paint failure.

 

[ls1mike]

Yes

Mine does the same thing.
