Hey guys,

So a car ran into a fence on a property I help maintain about a year ago. The lady had a seizure while driving, was pretty bad. Anyways, we rebuilt part of the fence. The fence was all redwood 2×6’s painted with a latex paint. We primed the new 2×6’s with Zinsser Cover Stain oil based primer, waited about 24 hours and painted over it with latex paint.

Fast forward a year: We just had more rain here in So Cal than we’ve had in a decade at least. There’s a lot of places on those new boards where the paint is coming off to show bare wood. The boards have checked quite a bit more than I’m used to on a fence and I’m not sure why that is. Deck planks I always figure will check more because they’re not allowed to move as much (that’s my guess anyways). The wood seemed to be in fine condition when we primed and painted. Not wet or dirty.

Anyone have ideas? Appreciate all your help. Thanks.

do you have any photos ?? what color is the paint ?
redwood has been used for outside signs for over a hundred years.
none of them last forever. in some locations, the wood moves more than
the paint, thus causing failure. I am thinking your local weather conditions
is the culprit – not the paint or your process.
remove all peeling and flaking paint. let dry and do it again.

Hey John!

I’ll get some photos. I can see the primer on the back side of the peeled paint. I’m thinking that the cracks in the wood allowed water to get the wood wet and the primer separated from the wet wood. We got a lot of continuous rain.

Does that assessment sound probable? I wonder what caused the wood to crack so much in the first place. All the older fence boards there (older meaning 10 years older) are nearly free of cracks.

sorry, I could not provide an assessment between the new and old wood
unless I could see it in person. the weather conditions is all I can guess at.
how many layers of paint are on the other boards ?
how many coats of paint did you use on the new boards ?

my last house had a “Dead Mans Curve” a half mile from me and they had a
white 5 board farm fence around the property. once a month (or week) someone
was always missing the curve and crashing the fence. sometimes before the new
paint even had time to dry. 10 years between crashes is a Blessing.

Jeez, that sounds gnarly.

The boards were bought new a year ago when we put em up so just the prime coat and 2 coats of paint. Thanks John, you’re always helpful.

Reminds me of the house I grew up in. I was not even 2 when my parents moved in, but I can remember it having a white picket fence. By the time I was 6 or so, my dad was so tired of constantly giving it he finally just took it down…

As for the paint peeling problem. You should have been fine putting latex over oil, IF the oil was completely dry first (which 24 hours should have allowed). I’d have to agree that it was most likely the unusually wet weather, but it’s hard to know without directly being involved to know what condition the wood was in before primer, or if you did all six 6 of each board thoroughly..

It really just sounds like bad luck with weather.

Did you rough up the wood at all? Often times wood comes planned, the smooth almost shiny surface doesn’t hold paint well.
