After the preparation the sanding begins. The first cut is done with course grit papers to remove old products and to make the floor flat. The differences in height between the boards are removed.
The large sanders are used across the grain of the timber. The most common paper used for the first cut is 36 or 40 grit.
The areas which cannot be reached by the large sanders are sanded by an edger, at the same grit paper as the rest of the floor. If filling of holes or boards is desired this is the stage where this is usually done. 50 to 80 grit papers are usually used for the second cut. The belt sander is used inline with the grain of the timber in this cut.
A finishing machine is then used to create the final finish. The grit paper used is of personal preference, however 100-150 grit papers are usually used. Coating with polyurethane, oils, or other products is done.
Sanding, restoring, repairing and refitting floors
We at Hamwoods have been sanding, restoring, repairing and refitting floors of any age for some time now (since 1966) and know and realise that there are a number of different factors and fundamentals within the working of wood, i.e; age, condition, species and of course what it sits on.
It has taken a lot of time, experience and hard work to get this standard of knowledge. To have the understanding of looking at any type/species of wooden floor and know exactly what of coarse of treatment/seal or how it will react or look after any work restoration or sanding has commenced. whether its victorian floorboards, timeless 1950’s herringbone old or new, there are certain rules/ techniques that only craftsmen like us will know from bringing back your old and tired looking floor to brand new, day one or keeping some of the old charm and charisma that a period property demands and transforms it into this clean original timeless looking floor with a sparkle.
We at Hamwoods believe that there are a lot more options to your floor than just sanding it back to its bare bone, sealing it up and off we go. Basically we we are there to give you ideas and a choice in what you want your floor to look and feel like. Most of all what it will do to the room where it sits in, i.e; will it make the room look lighter or darker? Will it reflect light or dampen it?
Any professional polisher who restores or sands wood will tell you that there is only one way to get to that standard of shine or smoothness is to go through the grades which means work your way through grades of sand paper starting from the 24-60 (coarse) and work your way up to a high grade 80-150 (fine). There is no cheating the system here if you don’t go through the medium grades you will only go through three times as many fine papers to get the marks the coarse paper left, or you will be left with the marks you can’t see until you seal, like we explained in the sanding and sealing section.
