Solid Hardwood, Engineered and Laminate Flooring - Applying Additional Polyurethane on Wood Floors

Hello: My daughter and son-in-law just bought a house (build 1900). The previous owners sanded and finished the floors within the last 2 years. The floors look dull and the polyurethane finish looks like they didn't put more than one coat on; looks like an uneven saturation. Will sanding with fine sandpaper and recoating with one more coat or possible two coats work to bring a more even finish and shine to it? We have thoroughly clean it with hardwood floor cleaner and are ready to begin but want to check before we do something that will make things worse.

Do people usually put the satin coat or a more high gloss finish on floors (living room/dining area)?

Any suggestions for fixing the scratchs that were made in some areas when they moved out?

Thanks for your help!

By what you have described you are correct. I am going to assume they only put one coat on or did'nt know how to aply the poly. What you will need to do is screen the floor to promote adhesion for the next coat. You can rent a buffer at the local tool rental and get a 150 grit screen. Screen the entire floor and do along the edges and corners by hand with 150 grit. Vaccum the entire floor and then wipe the flor with a cotton lint free cloth dampened with mineral spirits. Then apply the poly of your choice following the man inst. I don't recomend a high gloss because it will show every scratch, imperfection mark you name it. We recomend using a semi gloss it gives you a nice sheen and does'nt show scratches as much and holds up really well. As far as removing the scratches from moveing you will need to give them an extra hand sanding when you are done with the buffer if they are still there. Good luck with your project.
