This is all about filling in the cracks, or more to the point, filling the gaps between the boards.
Yes, it can be done.
Yes, it looks good when the floor is all free from gaps and spaces.
Yes, we can pretty much find the right colour to match your floor type.
Unfortunately, it is all short lived, as once the boards shrink and expand due to climatic changes the tightly packed filler cracks, breaks and pops out and quickly looks worse than when the floor simply had unfilled gaps.
Once the filler starts to come loose it can easily get caught up in the head of your vacuum, and as this putty has dried as hard as concrete, you can only imagine the scratches it can cause as you push the vacuum across the surface. Also, it's quite easy for a piece of loose putty to get under your feet and be dragged along, once again causing scratches.
Along with that, once the putty has broken through and damaged the coated surface, it allows water to get in under the coatings, which of course, creates another set of problems.
Although the filler comes in various colours which helps us to best match your timber species, it still lacks that light and dark variation that timber has. So, as we fill the gaps, the board on the right might be considerably darker than the board on the left, and then we put in the filler, which is not quite as dark as the right hand board, and not quite as light as our left hand board
So, in the end, we have filled the gaps, but in it's place we now have stripes of either lighter or darker putty,(in relation to the boards next to it) which can often stand out worse than the original gaps we started with.
Some days we just can't win.
Often we get asked to "Just do the bad one's". This seems fine initially, but once we have filled the biggest and most noticeable gaps, the second worst one's now become the worst one's and so on it goes.
So, for those reasons we *do not* recommend that the gaps be filled
However, if, after all that, you still decide that you would like to have your floors filled during the sanding and polishing process, you can rest assured that we will take the job very seriously and do everything possible to produce the best results. The putty we use and recommend is Timbermate, which is a water based filler coming in many, many colours giving us the best chance of matching your timber species as closely as possible.
The putty is mixed to the consistency of toothpaste and is then forced into the gaps with a flat blade scraper, or putty knife. This filling is normally done after the first sand has been performed and then once dry, it is sanded off when we are doing the intermediate sanding. This leaves the floor flat and filled and if any of the filler shrinks as the water content dries out we still have plenty of time to touch it up prior to our final sanding.
Here is a new floor with gaps that have appeared since it was laid.
The filling is mostly done after the first sand has been performed

The idea is to slightly overfill the gaps so that the excess can be sanded off level with the floor.
This leaves us with a large area filled and ready to be sanded off in the next sanding process
There all done. Looks good too.
