How To Tell If You're Buying Good Quality Lumber

Posted on: 11 November 2022

Lumber is a common building material used in everything from construction to furniture making. It is important to know how to identify good quality lumber to avoid costly mistakes or subpar results.

Here are two main signs of good quality lumber. 

The Boards Are of Consistent Thickness

Thickness is an important factor to consider when purchasing lumber because it will affect the stability and overall appearance of your project. Good quality lumber is milled to be of consistent thickness, which means that the boards will be less likely to warp or cup over time.

If the thickness of the lumber is not consistent, it's more likely to cause problems down the road. For example, uneven boards can create gaps or make it difficult to attach pieces together. When one board is thicker than its neighboring boards, it can also make your project look unfinished.

The problematic board will need to be planed down to match the thickness of the thicker boards. Not only is this an extra step that takes time, but it can also be expensive if you have to hire someone to do it for you.

The Lumber Is Free of Knots 

Knots refer to the places where branches have grown on a tree. When the tree is cut down and milled into lumber, the knots become embedded in the wood. While some knots can add character to a project, too many knots can make the lumber weak and difficult to work with. In general, the fewer knots present in a board, the higher the quality.

Knot-free lumber is also less likely to crack or break over time. The knots create weak spots in the wood that are more susceptible to damage. If you're using lumber for a structural project, it's best to avoid boards with knots altogether.

Too many knots can also affect the way the lumber takes stains and finishes. The knots are usually a different color than the rest of the wood, so they can absorb stains differently. This can create an uneven appearance that is difficult to fix.

You might have to use a pre-stain conditioner to help achieve a more even color. And even that might not work if the knots are too big or too many on the boards you use.

These are just a few of the main signs of good quality lumber. If you keep these signs in mind when shopping for lumber, you will be sure to get the best lumber for your project and avoid any costly mistakes.
