Is that a PROBLEM if solid wood flooring looks different in color?


Color different of solid wood flooring is mainly because of the differences in wood species, origin, grain and so on. Color difference is a natural situation for every solid wood flooring. Hereinafter, we will talk about these.

Cause 1: Color difference happens in root and top

Some solid wood planks are made from root while some are from treetop. Influenced by growth time and sunshine duration, the wood root material is darker than top material. As a result, the wood flooring that made of root is diverse as the treetop wood flooring in color.

Cause 2. Color difference in heartwood and sapwood

The outer ring of wood root and stem has live cells, and perform a function to reserve substances, conduct water and inorganic salt, which is called sapwood. And the part inside secondary xylem that stop reserving and conducting is heartwood. A piece of solid wood flooring could be more darker if it is more nearer heartwood part, meanwhile, the density is higher.

Cause 3. Different sawing methods result in color difference

According to different sawing methods, the sections of plank are typically crosscut, plainsawing and quartersawing, and the last two methods are more frequent used in flooring industry. The sawing patterns of wooden boards can affect the color that they show.

Plainsawing is perhaps the most straightforward way to cut rectangular-profiled boards out of a round log. The annular rings are generally 30 degrees or less to the face of the board; this is often referred to as tangential grain. The resulting wood displays a cathedral pattern on the face of the board. But depending on where they were cut out of the log, plainsawn boards can have substantially different grain patterns, which can cause it to expand and contract in different ways.

Quartersawn wood is created by cutting a log lengthwise into quarters, then creating a series of parallel cuts, with the middle cut being perpendicular to the tree's rings. Quartersawn wood has an amazing straight grain pattern that lends itself to design.

In quartersawn wood, the grain patterns are relatively consistent, so the end product is stable, which makes it preferred by many woodworkers. It might include medullary rays and wavy grain patterns that some people prefer over the patterns that are revealed through the other sawing methods.

Cause 4. Color separation process is necessary

Unfinished solid wood plank has no color grade and the color difference could be more distinct after finishing, thus, a regular flooring supplier would separate flooring products on basis of color grades, usually 2-5 levels.

Cause 5. Pay attention in flooring installation

Because of the above reasons, color difference is an inevitable nature of wood flooring, you need to do color separation again as your own like in installation if you don’t want widely color contrast. For example, to install the similar colors together, and put the high disparities in shaded place.

Generally, flooring that directly made from natural plants, such as wood log, bamboo, is quite acceptable to have color difference, which is decided by characteristics and structure of plants. Different density, different light-absorbing capacity and different finishing performance are all determined that even for the same one plank, color and grain could be various, however, color difference is also one of the nature features of solid wood flooring.

About Us

Global ZX Floor Doctor Limited Professional China Floor Inspector We focus on floor inspection only! After high school, Peter Zhang (President of Global ZX Floor Doctor Limited) directly went into foreign trade for 5 years. This trade normally has nothing to do with the inspection work, but it led to his first connection with import/export business, and made him know clearly about the different desires of international buyer and seller. From 1995, Peter started to run flooring export business of his own in China, called “New Century company”. The export volume of this company was in the top three of local area since 2003. This experience also introduced many important friends with sparkling ideas to us. And in 2012, our factory “VGreen flooring” was first founded.
