This is your primer on lumber, wood and wood related materials. Essentially you have structural load bearing grade wood which is heavy, high density and rot proof – and finally the DIY wood, which is pleasant, easy to work with, cheap and light.
The letters mark the grade of the surface, AC means it has a top quality face and a less pleasant back face. Use for furniture and paneling jobs where only one side is visible
This is construction grade plywood, it’s filled with knots and the x stands for the adhesive used in fabrication. It means it has limited resistance to moisture.
Almost water proof right out of the box. Stains, glues and finishes very easily, a shame it’s not all that easy to find.
Hard to find and staining is a bit difficult but it’s an easy wood to work with and the end result looks amazing.
Lumber that is already cut to some standard sized and is ready to build. The general size is the regular 2×4, which is usually 1.5 in x 3.5 in.
The heaviest softwood available on the market. And great for any load barring and structural uses.
HDF or hard density fiberboards. A budget option for surfaces where you don’t need impact resistance, water resistance, tensile strength and impact resistance.
Plywood made from hard wood, very resilient structurally and suitable for floors and walls
Great value, great as construction lumber. Less reliable for smaller DYI uses.
LVL is structural grade plywood. It is, however, harder to treat against moisture so use it for inside jobs mostly.
High density and tends to burn when using high-speed cutters. It also has a tendency to stain unevenly.
High-density fiberboard, use as filler when you need clean surfaces and complex cuts and edges. Use a high-quality sealer.
Pleasent odor, strong, beautiful grain, rot resistant, economical and easy to work with.
Great versatility, just check the rating…OSB 2 is limited in load bearing capacity and moisture, while OSB/3 is sealed.
Sugar Pine/White pine
Light soft pine, with a lot of wide resin groves. Glues and cuts very easily.
Light weight, but stronger than regular SPF(spruce, pine, and fir) plywood.
Low-density hardwood, the quintessential utility lumber
Amazing strength to weight ratio a pleasure to work with due to the specific odor it creates while processed.
Canadian Grouping of Spruce-Pine-FIr. Generally a marketing gimmick.
Wood that is treated with termites, exposure, and rot. A pressure treated wood can last up to 20 years more according to some manufacturers.
Southern Yellow Pine
Amazing durable, beautiful and easy to work with. Perfect wood for DIY. This is the densest and strongest pine on the market, still a soft wood but great for almost all applications.
