Lets discuss the whole process briefly

1. Removing the old finish

Removing Old Finish

Before applying your lethal weapon, you first have to make your battleground ready. And in this respect, removing your old, turned, rugged floor finish is the primary job.

This step is very tedious, but without proper preparation of your floor, your final result won’t be the same as you wished it to be.

  • Take the belt sander and set it at 30-36grit.
  • Work on the small surfaces to know how much sanding your floor needs to remove old rugs.

Don’t expect too much if you are sanding for the first time. And don’t get upset if you sand too much. You can always cover that up with the final finish.

Are you done with removing the old finish? Let’s move on to the next step.

2. Clean the Floor

Clean The Floor

Okay, you have removed your old floor finish. Now it is time to clean your floor to start sanding properly. Take the vacuum cleaner and clean the whole floor area.

Note :Make Necessary Preparation

So, you have cleaned the old finish. Before starting the sanding process, you ought to do something, or you will regret it afterward. Remove all the curtains, mats, and chairs from the room. If there are items like a piano or sofa, cover them. Seal the room so that your sanding doesn’t affect other rooms. Try to wear a face mask and goggles for safety. Keep the windows open.

3.Sand the Floor

You are all set to sand your floor; if you have done the above steps correctly, you can sand your floor. But before sanding, you have to determine whether your floor needs longitudinal or diagonal sanding.

If your floor is in a warped and sorry state, you would have to sand the floor diagonally and then finally longitudinally for a smooth finish.

But in case of a reasonably good floor state, you won’t need to sand the floor diagonally. Longitudinal sanding will do.

Sanding Diagonally

  • Set the grade at 40-60 grit and start sanding from one corner of the room.
  • Move the sander diagonally until you reach the opposite corner of you starting point.
  • Tilt the sander once you reach the opposite end and lift the abrasive.
  • Start the same process in a parallel line. Make sure every following sanding line overlaps the last line slightly.
  • Sand the whole room in the same process.

Pro Tip:- Try to sand every line at the same angle. Do diagonal sanding twice.

Sanding Longitudinally

  • Start sanding at 80 grit from the same corner where you started diagonal sanding.
  • After reaching the opposite corner, tilt the sander and lift the abrasive—resume sanding in a parallel line from where you stopped. Make sure the new line of sanding overlaps the previous line.
  • Carry out the whole process by moving the sander back and forth throughout the room. In the end, switch the gear to 120grit.
  • Repeat the whole process once again. Double longitudinal sanding will ensure a satisfying finish.

4. Cleaning the Surface after Sanding

Retake the vacuum cleaner and remove all the wood chips and dust.

5. Finish with an Oil-Based Solution

Take a respirator and a broad brush to undergo this step. This is the final step of your brand new floor. So, apply the oil-based solution thoroughly and wait for the whole room to dry up.

Congratulations! You have a new floor, and all credit goes to you.
