Guide to Floor Sanding
After removing the carpet (if there is any), hardboard, tacks and gripper strip use a nail punch and hammer and punch down all nails at least 2mm under the wood surface. Also countersink any screw heads.
By doing the above you will make your abrasives last a lot longer! Then you should start with an abrasive, either our cloth floor sanding belts or sanding discs would be ideal.
Depending on the state of the wood decides where you start with the grits. (for really rough wood you should be looking to start between 24 & 36 grit).
You should start by sanding the floor until it is flat and true. If the wood is uneven the abrasives wont sand properly.
Make sure you sand thoroughly and don’t skimp on the abrasives!
When finishing wooden floors it is vital that you are thorough.
