Did the floors get sanded? Looks like uneven sanding - over/under wood.

Thank you, G&S, for responding so quickly. I appreciate your time. The new floor that I installed was unfinished. When I laid the Invisible down, I experience major lap marks. I think that I laid down too thin of a coat and it was possibly drying before I got to the next section. I continued to lay the second and third coats, thinking that the lap marks would calm down. They didn't, so I decided to sand everything down and start over. I was afraid to use a drum sander, so I used a rectangular "buffer". I used 60, 80 and 120 grit. Now, I'm thinking that I should have just done the full sand and started with the 40 grit. One mistake turned into another. Questions: Would resanding fix this? Should I use Loba Easy Prime? What do you mean by over/under wood? Thank you so much for your time and knowledge. Dale

Yes, you would need to sand it to repair it. The humidity has changed since you originally finished it. It is normal for boards to shift and move.

It can be hard to tell if, Invisble has been sanded off sometimes. What you can do is water pop the floor after you do your first cut, whether it's 40 or 60 grit. Water popping will help reveal areas that has leftover finish.

Easy prime is not needed.

So, my plan is to resand starting with the 40 grit using a rectangular orbital sander. What do you make of the first picture that shows Invisible definitely changing the tone of the wood? The left side of the picture is the sanded section, and the right side has the Invisible on it. The Invisible side is yellow compared to the sanded section. It's not really close to being "invisible." Thanks, again for your time and knowledge.

Different batch of finish. Also, depends how well you shook the bottle and how heavy you applied. a slight difference will yield different results. its the main reason why stain repair is so difficult.

Thanks and God Bless.
