Brown Color From Waqter Leaking On Wallboard ?
Hello,
Just curious- Water leaking on plaster wallboard always seem to stain a brownish color. Doubt that the brown is from anything in the water directly, but perhaps ? More likely it's some chemical reaction. Anyone know what actually causes the brown color ? Bob |

More likely it's some chemical reaction. Anyone know what actually causes the brown color ? The water dissolves various brown chemicals in the things it runs over: shingles, dirt on the shingles, roofing tar, roofing felt, plywood, rafters, nails, insulation, dirt on the insulation, paper on the wallboard, dirt on the wallboard, nails or screws in the wallboard, dirt in the joints. Did I mention there's dirt on some of these things? :-) -- Steve Bell New Life Home Improvement Arlington, TX |

Bob Since wallboard exposed to clean water doesn't have any coloration, it seems logical that the water has dissolved stuff in the roofing/ whatever materials on its way to the wallboard, hence the colored stain.

I think it's more than likely salts dissolved by the water, perhaps w/ some iron, but as noted exactly who/what I'm not certain (and not inclined to really go digging altho I suspect one could come up w/ some reasonable candidates w/ a little digging). -- |
