All you need to know about Plywood

There are different types of plywood and it can get quite confusing when someone who has no knowledge of plywood has to make a purchase. So why do we need to buy plywood instead of hardwood?

Here are some advantages of purchasing plywood.

Plywood has a dimensional stability. Using them in construction means that hardwood plywood will not shrink, swell, or warp as much as lumber. This makes plywood have uniform strength.

Plywood can also be bought in terms of thickness, there are various sizes based on the various uses it has. It can also be noted that plywood can also be stained and painted in a more uniformed manner than just ordinary lumber. Therefore, plywood is the perfect product to be used in construction over ordinary wood.

Not everything is perfect, and the same applies for plywood as well as it does have its limitations. There are various factors that play into the purchase of plywood. The cost of plywood is mostly high and it gets difficult to gather up a high amount of plywood for large construction projects.

Compared to solid stock on a board-foot basis, hardwood plywood definitely is more expensive.

There is a limited selection of stock and it becomes difficult for the customers to procure their required amount. Because the dealer’s stock and what’s in demand, may only have three or four types of hardwood plywood, such as the popular oaks, birch, and mahogany. You may be able to special-order other types of hardwood veneers, but you’ll still be limited to a dozen or so of the most common, and no exotic woods.

There are also different types of grading involved, and this is mostly based on the quality of the wood. The different uses of plywood can also help in deciding the overall grading of the plywood. For construction, the thickness will be more while for coating purposes, a thinner layer is used.
Hardwood plywood grades, set by both the trade association and individual mills, cover varying degrees of quality. But you need to acquaint yourself with only those in the table on the following page.
While not part of the grading standards, the classification of hardwood plywood as either Type I or Type II becomes important to you if your project will be used outside. Most hardwood plywood has Type II adhesive, a somewhat water-resistant bond. For outside applications, you’ll want hardwood plywood bonded with truly waterproof Type I adhesive.

So before you go off shopping for plywood, take advice from an expert and get the right plywood for you.
