Water Marks in carpet after encapping?

[dankite83]

Any update on how this turned out? I know I'm a little late to the party here, but to me it looks like the carpet may just need vacuumed really well. Maybe even combine the vacuuming with the use of a crb (dry) or pile lifter. I have seen what appears to be the same problem as your picture shows a few times. Every time it has happened it was on carpet that seemed to have a never ending supply of dry soil, combined with foot traffic during a longer than usual dry time. My assumption is that you are simply seeing the encap process do its thing. You can just visually see it this time as the (possibly over applied) encap polymer is "encapsulating" the abundance of dry soil. The darker areas are where the foot traffic has broken the polymers and/or wet the carpet. In my cases, the quick fix to restore the appearance of the carpet has been to vacuum and or crb the carpet.
