But first, think about the kinds of physical motions, weight loads, and environmental factors that your specific floor will have to withstand. For diverse uses, plywood comes in a variety of kinds and grades, in addition to thickness levels. Some of them might not be suitable for your purpose.
So, here are some things to check for while purchasing plywood flooring:
When you get the chance, ask a plywood maker how they establish the cross-graining in their products. Some manufacturers only place the plies at right angles to one another.
Look for higher-quality plywood plies that are inclined in stages of 45 degrees (such as 45, 90, 135, etc.) for flooring. The plywood is stronger as a result.
The strongest plywoods are made with this type of phenol-formaldehyde resin. These are resistant to extremes of heat, cold, and moisture. For plywood used in exterior and marine applications.
Although less sturdy than Type A, this melamine-fortified resin produces plywood that is strong enough for outdoor use. Some structural plywoods that can be used as concrete formwork feature Type A or Type B bonding.
Type C and Type D are urea-formaldehyde resins that are less strong. They are used by manufacturers to make plywood for interior use. These plywoods shouldn't be utilized in structural applications since they can't support significant loads or strains.
You should only take Types A or B into consideration for plywood flooring, subfloors, and underlays. (This will also depend on the specifications of your construction project.)
Where will your plywood floor be installed? Choose plywood that has been treated or subjected to a preservative if it will be exposed to the elements and other harmful organisms (such as termites and fungus) that might cause damage.
Here are some instances of plywood that has been treated to stop decay:
Preservatives are incorporated into the veneers before manufacture.
Extra pressure is applied to the plywood.
After manufacture, a hard top preservation coating is placed on the surface.
Additionally, the look or finish of the plywood's outside veneers is graded separately.
Grade A: This is the best possible grade. It indicates that the plywood's face or exterior veneer surface is smooth and lovely in quality. Choose plywood with this grade if you want a clear finish for your flooring.
Grade S: In this grade, the exterior veneer accentuates more of the wood's inherent qualities. However, it is still ornamental enough to be used in transparent finishes.
Grade B: Veneer-grade plywood that is appropriate for high-quality paint finishing, such as that required for walls or even certain floors, is available. On the surface of this material, you could detect knots, tiny holes, or filled cracks.
Grades C and D plywoods feature several obvious flaws or blemishes on their outer veneers. These are typically employed in structural applications (such as plywood bracing). This veneer grading is what plywood used for subfloors and underlays frequently has for flooring.
