This is a red oak hardwood floor that we installed raw and then refinished with a natural seal coat and 2 coats of polyurethane. The floors are shiny because they are wet. The client we did this floor for requested a semi gloss finish.  When we install a raw or a prefinished hardwood floor the wood needs to be delivered 3 days in advance of install so that the wood can acclimate to it's environment. With a prefinished floor it will get a vapor barrier put down before the floor is installed. Once the floor is installed we can also install trim with quarter round or just trim. When a raw wood floor is installed we also install a vapor barrior then it needs to be sanded then  a sealer/stain needs to be applied. Once the sealer stain is dry we then begin to apply the polyurethane. The products we use are Dura Seal.  We can apply either a water or oil based polyurethane.
