We have recently bought a new house, well a new old house. It dates from 1900, we have taken the carpet up ad are now looking to sand back the exposed original floorboards.
We plan on giving the floor a light sanding, as it smooth just somewhat dirty/cosmetic imperfections. Is the correct process to use a fine sandpaper, and then possibly an intermediate if necessary ? We will be using a large commercial floor sander.
After sanding we envisage the wood being a lot lighter, and therefore we will need to stain it. What stains are best oil/water/spirit based ?
How many coats of stain are required ?
After staining it is necessary to apply a varnish ? We intended to apply two coats of clear varnish. The first coat can be watered down, as it is used to seal the wood ?
Does our plan look like a good one ?
Just in case anyone is interested, the floor is all done.
We used 3 coats of ronseal diamond hard floor varnish. Before the final coat of clear varnish we sandpapered with fine grain by hand, and wiped with wet cloth/let dry for couple of hours. This got rid of a number of cloudy marks that were present and caused, I think, by our slightly imperfect sanding.
So one thing I learn't - don't be afraid of the rough paper and really giving the floorboards a good going over. We got them smooth, but there is substantial variation in colour where different amounts of wood were taken off by the sanding/levelling process,however we quite like this the distressed/aged look; They are over 100yrs old after all.
