Wood is a hydroscopic material which means it absorbs moisture from the air relatively slowly compared to other building materials. Here are some of the most common problems that occur while installing hardwood floors––including cupping, crowning, and squeaky floors––and instructions on how to fix them. High moisture content is the main culprit. A video from Build Direct points out that you shouldn’t install hardwood floors in a room that contains a lot of moisture. If not, it could be permanently damage and in need of sanding and refinishing or, in some cases, board replacement. To fix floorboard cupping, you can simply sand the floor to make it even. Crowning can also be caused by previous floor cupping. alignment, uneven wheels, incorrect drum pressure, imbalanced drums, loose V-Belts, or failed. The wood will bend up in the middle and down on the edges. For installation questions, please consult the National Wood Flooring Association Installation Guidelines. When you say that the moisture is 4.5%, what was it measured with?

However, in instances where cupping/crowning happen due to leaks or excessive water, the damage may be more sustained. Solid wood flooring tends to be more susceptible to these problems as the wood planks are made of solid wood the entire way through, whereas engineered wood experiences less issues because only the top layers of the wood are made from the wood species in question. The wood flooring, however, doesn’t come without a few limitations. Cupping: Cupping happens when both side edges of the plank seem to rise up out of the floor and cause a “dip” to appear in the middle of the plank. Splits and checks also can appear. If there are already chatter marks on your floor one great way to fix them is by using a multi-disc sander like the Lagler Trio. The best way to prevent chatter marks is to make sure your big sander is operating perfectly. And it is not throughout the entire 1600 sq. Really helpful information thanks for shairng. Cupping and Crowning Cupped Floor STEP 1. They are traditionally caused by some sort of failure in the big machine sander. Crowning is characterized by wood that is raised in the center and dips down on the long edges of the planks. bearings are common issues that could produce chatter marks on hardwood floors. This makes the wood appear to be in a “U” shape. Once you are sure that the moisture problem has been corrected and the moisture content of the floor has returned to the right level, monitor the floor for a few weeks to see if the planks return to normal. Place mats under areas that are susceptible to water spills such as underneath a pet bowl or next to the sink. (See the picture at the top of this post for an example of a cupped floor.). Wood floor crowning is the opposite of cupping and happens when the center of the board is higher than the edges. First and foremost address the source of the moisture and remove it. If the floors were installed with improper nailing schedules or the incorrect adhesive, they will be loose and cause noise. The most common reason for the halo effect on a hardwood floor is when different sanding approaches are used in the same area. What is the species, where are you located, how wide is the flooring, and is this material solid or engineered? Moisture is at 4.5%. They did go around with a moisture meter on my sub floor and the new flooring and said that they were close enough to each other that there would be no issue. Crowning may not only …
