Q: I was told that adding a 4th coat of poly would look the same as 3, but I’ve found that the floor is more glossy, not the look of a hand rubbed finish it had with 3. Is there anything that can be done at this point to remove the glossy appearance?
A: It can happen that there is a slight difference between different batches of finish. When working with any sheen except gloss it is important to stir well so the flattening agent that takes away the shine is well dispersed throughout the product. The only thing you can do is give it another coat. This has nothing to do with it looking more shiny as you apply additional coats of finish.
