Why is there a lot of black knots in the purchased hardwood floor? Wooden floor knots, floor black spot?

A natural wood floor, the wood knots is also part of the product. Natural timber knots is bound to exist, and the manufacturer will repair the knots, generally according to European and American needs and use black or brown to fill.

Product users do not need to worry about the knots will fall off after repair. After nearly one hundred years of use, there has been almost no phenomenon of the falling off by itself after repair.

If the customer has special requirements for the product, please be sure to clearly inform the supplier do not want to have knots, a professional floor supplier, often have two types of products, one is the normal products that is natural products, the other is the selected products. The flooring industry is known as “PRIME GRADE” or” AB GRADE”.

Knots and any voids (that is hollows associated with them) are permitted within limits in all three grades. The knots
must be sound (will not fall out), however in Select Grade the splits that can be seen within these knots, known
as knot checks, are not permitted. For this reason even though the size of the small knot in the first photo may be
within Select Grade limits, the knot check would cause it not to meet grade. Due to this, even small knots are often
not found in Select Grade boards. Knot checks are permitted in both Medium Feature – Standard Grade and High
Feature Grade. The knot in the second photo meets Medium Feature – Standard Grade requirements and the knot
in the third photo meets High Feature Grade.
