ask the manufacturer.

Good idea… Thank you

Are those white lines in the joints on the refinished floor?

I think that’s the poly… There’s always kinda been white lines between the spaces…

Two days? How long did the water sit before being wiped up?

From personal experience, waterborne finishes aren't as resistant to water as is oil poly, so avoid leaving puddles or setting wet items on the floor.

About 15 minutes

The stain is gone now so I’m hoping it just needs more time to cure..

" I think that’s the poly… There’s always kinda been white lines between the spaces… "

Means the finish is not adhering properly for some reason, not dry enough before another coat applied being one reason, not properly prepped, etc.

Do you think it needs to be sanded down again?

It's bamboo. There is a lot of glue in it. More glue than plant cellulose. I'd bet it is an incompatibility issue generated by that. Most finishers will not touch refinishing bamboo. Only replace it. With something else.

The stain is completely gone now? My cleaning lady came 30 minutes after I left and she couldn’t find it. I’m hoping it needs more time to cure. 🤞🏻

"Means the finish is not adhering properly for some reason"

I believe this is not necessarily a correct assessment. Maybe it's correct, but can't be reached with the meager evidence at hand. To my eye, only one side of the bevel looks light, and it's the one facing the light source. One can see the same effect on the old floor, where the left edge of each bevel is being illuminated by a light source from the right.

In any case, it's unrelated to your current issue, which appears to no longer be an issue.

Best Regards.

Thank you Timothy! Time will tell…. 🥺. I’ll keep you posted.

We’re hoping to get the upper floors refinished this summer. They’re bamboo too… I guess we’ll wait and see how it turns out. It’s still better than the dark floors. 😫😂

Here’s the other areas..

Typical of entry level water base finishes. Water spotting is normal. When it dries, it disappears.

Thank you.. it does disappear when it dries. Do you have a water based polyurethane you like or recommend?

Thank you
