When you sand your hardwood floors you use coarse sanding equipment to remove all of the finish and stain from your floors as well as smooth out the wood underneath those layers of stain and sealer.
The order to sanding and finishing wood flooring.
Before you start sanding remove everything from the room and vacuum the floor.
If the floor happens to be raw wood paint can seep into the wood and stain it almost beyond repair.
When a wood floor loses its luster the usual solution is to sand it down to raw wood and completely refinish it.
But often that s the wrong solution.
It would be a total waste of time and effort to begin with 80 grit on the pre sanded veneered wood and you would risk sanding through.
You can finish sand both of these surfaces with 180 grit for example but you might begin with 80 grit on the solid wood and 120 grit on the plywood.
After sanding fill in holes in the floor with wood putty or wood filler.
This is an intensive process that strips everything from the floor by grinding it down to the natural wood underneath all that shine.
Refinishing hardwood floors is the right solution.
Sanding the floor will kick up a lot of dust so protect light fixtures and tape over electrical outlets.
Spot test the stain or finish to see what it looks like on the floor before applying a coat.
You will remove a lot of wood stock even when sanding the hardest of wood floor species.
Use 24 grit sandpaper if there are sander flaws e g.
You ll need to sand the entire floor not just one section.
You would have to sand deeply into that raw wood to remove the paint pigment.
But it only makes your job more difficult plus it gums up the sandpaper.
Use 100 grit for all purpose sanding and 120 or 180 for the finest finish but follow power tool sanding with hand sanding.
This is also usually a good.
Power tools leave hidden scratches that show up later.
Be sure to work in well ventilated rooms when sanding or applying stain or finish.
Paint that has dripped and hardened on a sealed surface will come off floor sanding.
All wood floors are protected by a clear coating that eventually becomes scratched scuffed and dull.
Swirl marks in the wood or if the finish has worn down to the wood in certain areas.
Use when there is a good deal of flattening of the floor needed.
Sanding a wood floor is a multi step process.
And always sand.
That way you ll get a heads up on and hopefully the knowledge to avoid some of the problems you might encounter and some of the mistakes beginners make.
