Gapping and Finish Issues
Q: We purchased a new home in August 2006. The builder installed pine flooring throughout out house. We realize that pine is quite soft and expected to have many scratches. Overall, we were satisfied with the way it came out, and it seems to be holding up quite well. However, we've been having a few issues with certain areas.
I've noticed that there are some areas where the wood appears to have shrunk--leaving gaps between the tongue and groove planks. It's quite noticeable in one of the walk-in closets where there is a outlet for the AC/heat. Is there any way that I can fix the gaps? Some are as wide as 0.5 cm-1 cm.
The second issue is that there seems to be quite a bit of wear with the polyurethane in areas where chairs are. I realize this is from the constant rubbing of the legs on the floor. I have tried installing plastic caps on the chair legs and even felt under the couch legs, but this doesn't seem to help. The builder claims that he put 3 coats on the floors, but we suspect that only two were put on. Is it because there weren't enough coats of polyurethane, or is this something to expect from pine or just wood flooring in general?
Lastly, I have one area which makes a loud "crack" sound when walked across. The ceiling below the area is finished, so I cannot get under the floor to fix anything from that side. Is there anything that I can do to stop the crack noise?
Thank you in advance for your help! I look forward to hearing your suggestions!
Sincerely,
Deb
A: A very important thing to keep in mind is that wood is a natural product and movement (expansion and contraction) from heat/cold and moisture in a home is most common in solid products like your Pine flooring. The questions I would ask is what temperature is your house kept at throughout the year? Does it remain the same or does it change based on season? Also, you might want to look into having the relative humidity of the air in your home. If it is too dry this can cause gapping and the solution is to get a humidifier to bring the moisture level of your home up to around 35-40%. Normally wood floors are best in the same environment best for your average person, around 63-65 degrees Fahrenheit and around 40% moisture in the air.
With your second issue in regards to the finish, the most important things to keep in mind is to use furniture cups on all of your furniture. You should be able to find cups similar to your plastic one, but with felt pads for the chairs. Beyond that it could be that the site finished used is not as tough as some as the others available. The finish is the only thing to put in question here, as the hardness of the floor won't help/hurt the durability of the finish. The number of coats can help here, but the actual finish used is very important. The rule of thumb for site finishing is to lay multiple thinner coats because this will allow for a stronger finish in the end.
What you might want to look into is getting your floor re-screened. This process involves buffing the top layer of the finish (roughing it up mildly) then applying new layers of finish. Should you choose to go this route, I would use either Bona's Traffic finish or Glitsa's Infinity II.
In regards to the cracking noise you are hearing, this is usually caused when the boards of your subfloor is not fully anchored to the joists below. This movement will cause creaks etc. Your only options to repair this would be to either remove the flooring then screw the subfloor area down to the joist, or to work from under the joist where the ceiling is finished. Either of these will be a pain because your removing finished areas.
You could try hiring a third party inspector to come out and view you floor to determine if there is anything that can be done or determine if your builder needs to fix things because they were done improperly.
