Restaining engineered hardwood floor

Hello. I just bought a house which needs a little renovation. I will start with refinishing the hardwood flood that the house is covered with in 85%. I would like to restain it with a light color, preferably light grey. The floor was replaced in 2007. It is laid in diagonal pattern.

Here are some details:

Species: Oak
Thickness: 3/8 Inch
Width: 3 Inch
Install Type: Glue Down or Staple Down or Nail Down
Grade: 3-Ply
Construction: Engineered
Edge Type: Eased Edges/ Square Ends

I sanded the the plank a little bit using a hand sander with 80 grit paper (took me about 3 minutes to get the stain layer off from that little piece), the wood is still very smooth and kinda slick.

Do you think that its suitable for sanding and restaining?
What type of sander (drum / orbital) and grit would you recommend?

 

Welcome to the forums!

That type of flooring isn't really suitable for sanding and refinishing. You only have a thin layer of wood on top and once you sand thru it the flooring is junk. A very light sanding and a fresh coat of poly is the most you can do. That type of flooring isn't made for refinishing.

 

It looks like it's solid, really depends on the thickness of the top layer!
