This may be the best idea yet. Using plywood for a countertop is smart. Cover the edges with trim for a finished, modern look that will look nothing like construction plywood. 
It’s something you should do by yourself, so you’ll need the right information. And the decision should be made based on your needs.  

Pros And Cons Of OSB

Oriented strand board (OSB) was invented in the 70s. It came from waferboard. Unlike chipboard or cork, OSB is made.


  • Fireproofing Option – One benefit of OSB is that it can be fireproofed. Manufacturers apply a fireproof seal to the wood that makes it fire-resistant. You can’t do this to plywood.
  • Cheaper – No matter how you look at it, a sheet of OSB is cheaper than a sheet of plywood of equal size and thickness. In some cases, OSB is half the price of plywood. But in most cases, it’s about 20-30 percent cheaper.
  • Thicker – OSB is thicker than plywood. It’s no secret that thicker sheets offer many benefits. If you’re paying less for thicker boards, that may be enough to convince you to choose OSB alone.
  • Larger Sheets – Not are OSB sheets thicker, but they come in larger sheets. You can still get them in the standard 4×8 sheets, but you can also get them 24 feet long. This makes large projects even easier.
  • No Knots – Unlike plywood, OSB doesn’t have large knots in the wood. Knots can break off and leave holes in wood and they are impossible to screw through without compromising stability. No knots are a good thing.
  • Stable – OSB is a plywood substitute for joists along with 2x6s or 2x4s due to the extra stability of the thickness and composition strategy. Plywood isn’t recommended for adding stability to joists.
  • Eco-Friendly – OSB is made with renewable trees, it is more eco-friendly. It also can be found without formaldehyde and in chemical-free versions.


  • Heavy – OBS is heavier than plywood due to the thickness and amount of wood packed into each piece. This can be a hassle with small construction groups or when used on fragile frames.
  • Hard To Waterproof – It’s not waterproof. The ends of OBS swell if cut. Plywood is water-resistant.
  • Not Attractive – You won’t hear of OSB being used for siding or as a flooring option. It isn’t attractive and is for sheathing alone. You will want to find something attractive to cover it.
  • Can Rot – OSB isn’t waterproof, so it can rot. 

Pros And Cons Of Plywood

  • Impact-Resistant- Plywood is more impact-resistant than OSB. This is why it’s used in workshops and worktables. It won’t split or dent when under pressure like OSB can, so it’s great for subfloors.
  • Many Variants – Plywood comes in many more variants than OSB. Markerboards, cabinets, and aircraft feature this wood. 
  • Nearly Waterproof – Plywood is water-resistant. It doesn’t swell when exposed to water and is permeable, so it allows water to pass through without absorbing it. 
  • Curves Well – Plywood curves much better than OSB does. It is often used in curved projects like eyebrow windows. Plywood is more pliable which makes up for its thinness and gives the thickness purpose.
  • Solid Wood – Plywood looks better than OSB because it looks like solid wood.
  • Longer-Lasting – Plywood lasts longer than OSB. This is due to its water-resistance unlike OSB, which absorbs and swells when exposed to water. However, the initial price may balance this out. 


  • Thinner – It’s as simple as that.
  • More Expensive – this is the number one reason people choose OSB. It is much more expensive than OSB for large projects. For small projects, plywood is great. But if you’re investing in building materials, OSB may be a better choice. 
  • Knots – it may not be a dealbreaker, but the knots on plywood can be quite annoying. They can leave holes, be in the way, and force you to play which way you will lay each piece. This isn’t a problem with OSB. 

Unfinished Plywood 

OSB has overtaken plywood on the sheathing market. A few years ago, plywood was more popular. Now, OSB has over 70% of the market share, over 20 percent from what it was two decades ago. 
OSB is not good by itself. Unfinished plywood is good for siding, floors, and more. You can varnish it so it looks nice and sleek.

OSB is greener. The reason why is OSB comes from small wood pieces or tiny-diameter trees. Smaller trees grow faster, which replaces OSB wood sources faster.
