How To Reinforce The Raw Edge A Plywood So You Can Put Screws Or Nails In It

What's the deviation between OSB vs plywood? This article dives deep into the pros, cons, and applications of both these sail materials.

Plywood and OSB are two of the most common sheet materials used in domicile building. The problem is, they're very similar looking products with a lot of overlap when it comes to their end uses.

Non only do these 2 building materials look alike, just there's a lot of defoliation about what makes them unlike from i another and how each should be used in construction projects.

This helpful guide to aid you understand the differences between plywood vs OSB so that yous tin choose which blazon is right for your project!

Let's leap in!

What's the Difference Between OSB vs Plywood?

Let'due south showtime with an overview of the differences between OSB and plywood.

• Toll: Traditionally, OSB is the less expensive choice, although this tin fluctuate depending on your area and the market place.
• Workability: OSB and plywood are both fairly easy to utilise. However, plywood can exist made into furniture and cabinetry, while OSB is used exclusively for structure.
• Capsule: Both are about interchangeable for use on roofs, floors, and walls. All the same, there is a heated debate well-nigh this, and we will dive into some of the arguments after on.
• Quality: Both OSB and plywood tin can be purchased at various qualities. Some are cleaner and more durable; others are less expensive.

What is OSB?

OSB stands for Oriented Strand Board. It's a manufactured building material that is similar to plywood, but they're non the same. OSB is fabricated of wood shavings compressed tightly together with resin or glue under high pressure and heat.

Many people prefer OSB because it doesn't require the harvesting of large copse. Instead, OSB can be fabricated from small trees grown specifically for this purpose, or the waste production from milling lumber.

There are several types of OSB:

• Standard OSB: Used for roofs, walls, and flooring. It has no special features, just you can find information technology in many versatile sizes.
• Zilch OSB: This type of OSB is made specifically for the outer sheathing of walls and roofs. Zip OSB has a waterproof, house wrap-similar bulwark pre-installed, allowing yous to speed up your project.
• Subflooring OSB: Subflooring OSB is shine and strong, and many types will have a tongue and groove at the edges, allowing for easy connections.

When Should I Apply OSB?

OSB is an less expensive alternative to plywood for large projects. Even so, OSB is not always the best choice for smaller, DIY projects.

It's good for roof sheathing, outside walls, subflooring, sheds, and other structural projects because information technology doesn't warp as easily every bit plywood does. OSB takes regular nails pretty well, especially when nailing into studs or joists below the fabric.

However, the crude cutting edges of OSB make information technology more difficult to adhere corners for smaller projects, similar boxes. Screws or nails can easily slide between the layers in the sides, so your box volition apace autumn autonomously!

Also, OSB doesn't have a existent-woods veneer, like plywood. The raw nature of OSB keeps prices low but isn't the most aesthetically pleasing. Even if you paint over information technology, you'll nonetheless run across the random texture of the wood shavings under layers of pigment.

However, that doesn't mean y'all couldn't utilise OSB for strictly applied DIY projects, like these storage shelves. OSB helps cut downwards costs when y'all just need a apartment sheet of wood that will exist subconscious under a bunch of stuff!

How Do I Use OSB?

Here are some things to keep in listen when edifice with OSB:

OSB and Moisture

OSB resists water initially, because the resin and glue holding it together volition repel wet...to a point. Once it becomes saturated, it's very hard to dry out out. OSB tends to bubble and swell like a sponge, separating the layers and rendering itself unusable.

Unfortunately, one time your OSB has expanded, it doesn't bounce back to its normal size when dry.

OSB Rigidity

OSB tends to be more than flexible than regular plywood. However, this doesn't mean that OSB is inherently weaker; it simply ways it can be a bit bouncy.

For example, if y'all're using OSB equally subflooring, you want to ensure that your floor joists aren't likewise far apart; otherwise, you may terminate upwards with some bending.

Using a thicker sail of OSB may remedy this issue. As well, consider using a higher-course subflooring OSB for the task.

OSB and Nails

OSB is not known to hold onto nails likewise as plywood. For this reason, some roofers prefer to use regular plywood, as they feel the shingles are more than secure.

However, y'all'll have to exercise your own testing on this one. Different nails and different types of OSB volition hold nails differently. When in doubtfulness, use screws!

Ofttimes Asked Questions about OSB

Is OSB waterproof?

OSB is water resistant, but not waterproof. The resin that holds the wood fibers of OSB together is waterproof, simply any cut edges volition expose the untreated wood fibers inside. One time those areas are exposed to h2o for an extended period of fourth dimension, information technology will swell and commencement to pull apart.

Applying paint or a waterproof sealant to OSB tin help to prevent wet from penetrating the surface. You can too discover exterior class OSB that will hold up better in the rain.

Is OSB stronger than MDF?

Strength depends on the thickness and manufacturing quality; notwithstanding, OSB is generally stronger than MDF.

What tin can I utilize instead of OSB?

Regular plywood is a proficient alternative to OSB. Though plywood is more than expensive, it tin can perform at the same level every bit OSB.

What is Plywood?

Plywood is a manufactured material designed for employ on all sorts of projects. Plywood is a sandwich of thin layers of wood, compressed together with adhesives in an alternating grain pattern. Plywood consists of multiple "plies" between 3 and 11 layers thick.

Depending on the type of plywood, there may be one or more hardwood layers on the confront, chosen a veneer. You tin buy veneered plywood in a wide range of forest species, and you can fifty-fifty find information technology prefinished to salve you a step! I used prefinished birch plywood when edifice my kitchen cabinets so I didn't accept to pigment or finish the within.

Plywood comes in several unlike types and grades:

• Grade A: Highest course. Sanded smooth, no knots, and all voids have been filled. Also called cabinet grade.
• Grade B: Second highest. Sanded shine, may accept upwardly to one-inch defects.
• Form C: Tertiary level. Unsanded and more defects. Best for subconscious uses.
• Class D: Rougher than C, may accept fifty-fifty larger defects. This is normally used for subfloors in identify of OSB.

Also, you lot may run across grades such as "BC" or "CD." These classifications indicate that 1 side is a higher grade than the other. Utilise the better form where yous'll nigh likely see the surface, and hide the lesser grade.

Proceed your projection in mind when choosing your plywood. If it will exist painted, you can apply a bottom form plywood since the imperfections volition exist hidden. I even took advantage of the crude texture of D form plywood when I congenital my son's home climbing wall, considering it false the cracks and grooves of natural rock formations!

When Should I Use Plywood?

Plywood tends to be the get-to lumber for all sorts of projects. Not only does plywood work well for structural projects, just it comes in handy for a wide diverseness of woodworking projects every bit well. I've compiled a list of 25 plywood projects for every room of your firm!

How Do I Utilise Plywood?

Plywood is incredibly versatile, but it's non without faults. Here are some of the downsides to plywood and how you can fix them.

Exposed Plywood Edges

While the face of plywood looks like solid wood, the edges tell a unlike story. The visible layers aren't exactly attractive, especially if there are voids or knots correct forth the exposed edge.

Luckily, there are a few ways to hibernate it! The easiest way is to apply edge banding. Information technology's a sparse strip of wood that comes on a roll, and has a heat-activated mucilage on the dorsum. Just iron it on to the plywood edge, then trim away the excess!

For a more durable cease, you tin cut thin strips of hardwood to the same thickness as your plywood, then glue and nail it onto the edge. This will exit a visible seam between the plywood and the solid wood edge banding, but it volition concord upwards better to clothing and tear.

Finally, you could just apply wood filler to the exposed plywood edges, and so sand information technology smoothen when dry. This method is simply recommended for painted furniture, just it's ameliorate than leaving the edges raw!

How to Prevent Tear Out

Those thin layers of plywood are fragile, and tend to leave splinters chosen tear out after cut. This can brand your project look less than professional, merely luckily there are a few ways to forestall tear out.

• Utilize sharp saw blades with a high molar count.
• Score your cutting line with a utility pocketknife first.
• Utilize painter's tape over the cut line to agree the wood fibers in identify.
• Cut with the nicer face down when using a circular saw, and cut with the nicer face up when using a table saw. The blade should e'er enter on the "good" side, so any tear out will occur on the back.
• Support the underside of the fabric with a canvass of foam insulation or a piece of scrap plywood.

Another option is to use a track saw with a splinter guard. This thin layer of clear rubbery material lines the edge of the runway, and holds the plywood fibers in place for a perfectly make clean cutting. You lot can learn more well-nigh the difference between a rails saw and a round saw here.

Plywood and Delamination

When plywood becomes waterlogged, it tends to dry fairly quickly and return to its original size. However, repeated exposure to h2o can lead to delamination or a separation of the layers.

If your project volition constantly exist exposed to moisture, you tin can use marine grade plywood to prevent this from happening. Information technology'due south fabricated with special waterproof glues that will concur the layers together, no matter what the weather condition brings. You can even employ it to build a boat!

Knots and Voids in Your Plywood

Some lower grades of plywood volition have knots and voids throughout the board. When plywood is layered and compressed together, in that location are often large knots in one of the layers. Sometimes, these knots fall out, creating voids.

These voids and knots tin create issues and weaknesses in a project. To remedy this outcome, consider ownership loftier-grade plywood. Baltic birch plywood is known for having void-costless layers and is the gold standard for article of furniture building.

Oftentimes Asked Questions about Plywood?

How Much Does 4x8 Sheet of Plywood Cost?

The price of plywood depends on the market and the type of plywood you're ownership. In full general, the thicker the sheet and the improve the quality, the higher the toll. Construction grade plywood made of pine will be much cheaper than cabinet grade plywood made of maple.

How Long will Plywood Last?

Plywood's lifespan depends generally on its quality and the corporeality of moisture information technology must endure. If you use it right and protect it from h2o, plywood will last a long fourth dimension.

What are the Disadvantages of Plywood?

Plywood can exist expensive, it's not as pretty as existent wood, and cheap plywood often has unseen knots and voids, potentially compromising your project.
