Floor sanding is not really a DIY job. It is in fact a job for the professionals. Anyway just in case you want to know how to sand a wooden floor I will give you a a little guide to sanding and restoring wooden flooring.
First of all you will need to use a belt floor sanding machine with a very coarse 36 grit on to remove all of the old seal and to level the floor. Always sand the floor going with the wood grain or at a 45 degrees angle to the grain Flooring services Leamington Spa.
Next you will need to start the smoothing process by using a 50 grit sanding belt. This will remove the scratches left by the previous 36 grit belt.
Next use a 80 grit sanding belt to remove the scratches left by the 50 grit sanding belt.
Next you will need a rotary sander or a buffer with a 100 grit or 120 grit disk to remove the fine scratches left by the 80 grit sanding belt. The buffer will leave the floor very smooth and prepare the floor for priming.
You will then need to apply a wood flooring base prime to prepare the wood floor for lacquering.
After you have primed the wooden floor you will then need to run the buffer machine over it with a 150 grit disk to remove any raised grain, leaving the floor very smooth.
Hoover the floor to remove all traces of dust and begin to roller on the lacquer of your choice e.g Bona or Junkers.
Next apply the second coat of lacquer after the first coat is dry.
