Chatter marks is a common term used to describe a rippling pattern of half circle marks that appear on hardwood floors as a result of improper sanding. Chatter for the most part is not severe and for the most part is a vibration issue. First of all if the floor is already stained it will require different sanding procedures than a floor that is unfinished.

Rippling in a wood floor is called chatter if the ripples are less than 1 1 2 inches apart and waves if the ripples are more than 1 1 2 inches apart. At any rate regardless the cause the only way to get rid of it is to sand the floor again. Although these marks are hard to detect. If the floor was simply sanded again in the same direction these marks would actually get worse.

While it isn t easy to prevent these marks taking the following precautions before sanding the floor can go a long way towards preventing these problematic chatter marks. Chatter are like little ripple lines closely spaced. He also talks about the difference between a butt joint and a lap joint. The wave is more likely an equipment issue.

Chatter can be caused by a loose sub floor just as an example. Poor seams on the abrasive belt drive belts and fan belts worn pulleys and bad bearings in the fan housing also can cause chatter and imperfections in the floor. Either way the result is not pretty and can. Wave is a repeat of the first imperfection that runs repeatedly over the floor and is typically more than 1 1 2 inches apart.

Deflection in the subfloor can cause chatter but that wasn t the case here. These marks are often referred to as chatter marks. In this case we removed the chatter by cutting the floor at a fairly steep angle with the big machine we didn t even need a multi disc sander.
