Mike Lamb Posted June 21, 2016 Report Share Posted June 21, 2016 I assume that rusted nail heads are bleeding through this vinyl siding. Very odd. This anomaly showed up at a couple places around the house. Can I assume that the stains cannot be removed or washed off?

Mike Lamb Posted June 21, 2016 Author Report Share Posted June 21, 2016 It's not face nailed. Can rust bleed through? That is what I am guessing. Link to comment Share on other sites More sharing options...
ejager Posted June 22, 2016 Report Share Posted June 22, 2016 If that's bleed through (which I doubt), it would be nails from the sheathing bleeding though the WRB as well as the siding as there wouldn't be nails in those locations to secure the siding... so not likely... It is interesting that the marks are aligned vertically - was the siding staggered? (to rule out some contaminant in the box pre-installation) Link to comment Share on other sites More sharing options...
kurt Posted June 22, 2016 Report Share Posted June 22, 2016 Did you get a look under the siding anywhere? Link to comment Share on other sites More sharing options...
Jim Katen Posted June 22, 2016 Report Share Posted June 22, 2016 Rust doesn't bleed through vinyl. Someone leaned a rusty thing against the siding. I'll bet that if you scrub the rust spots with some scotch brite, the stains go away. Link to comment Share on other sites More sharing options...

mjr6550 Posted June 23, 2016 Report Share Posted June 23, 2016 The positioning of the nails is too even for it to be something that was leaning against the siding, especially since the siding is not a flat surface. I once saw vinyl siding where you could seen marks on the siding from nails behind the siding. It was all over at least one side of the house. The stains were not from rust. I never did figure out the cause (or I forgot). Link to comment Share on other sites More sharing options...

I once saw vinyl siding where you could seen marks on the siding from nails behind the siding. It was all over at least one side of the house. The stains were not from rust. I never did figure out the cause (or I forgot). I'm suggesting that it's a thing that gets leaned against the siding repeatedly, at different heights and positions each time. I see nail marks on vinyl siding every so often, but they appear as light spots. I suspect that they're the result of different temperatures where the nail heads are. I've tried but have been unable to clean or wash away the light spots. Link to comment Share on other sites More sharing options...
Marc Posted June 23, 2016 Report Share Posted June 23, 2016 I'll throw in my two bits: It's reused siding. The stains got there when it was stacked for an extended period and existing rust stains spread to the adjacent piece of siding. Ain't got nuthin' better to post.

mjr6550 Posted June 24, 2016 Report Share Posted June 24, 2016 The pattern looks like it could match sheathing nails. I can't explain why it happened. Download Attachment: rust on vinyl siding.pdf 99.69 KB Link to comment Share on other sites More sharing options...

Download Attachment: rust on vinyl siding.pdf 99.69?KB The spacing is too narrow. Assuming that those bricks are 8" wide, the distance between the rust spots is much less than 16" Link to comment Share on other sites More sharing options...
mjr6550 Posted June 30, 2016 Report Share Posted June 30, 2016 I agree with you about the spacing, but it does seem to be a pattern. Link to comment Share on other sites More sharing options...
John Kogel Posted June 30, 2016 Report Share Posted June 30, 2016 Could have been a trellis for roses or grapes that was built against the siding. Link to comment Share on other sites More sharing options...
