OSB can be used on interior walls since it is strong, durable, and provides structural support. The wood strands add a chic decorative finish if you are wanting the walls to stand out.
Can I use OSB instead of drywall?
With the exception of some fire rating necessities, it really boils down to personal preference. Both OSB and Sheetrock can be used to cover the walls in a garage. Fire-Rated OSB and sheetrock each meet the fire code requirements for attached and unattached garage spaces.
Is OSB safe for indoor use?
For indoor use, buy OSB that uses phenol-formaldehyde or methyl diphenyl diisocyanate binders to avoid health hazards. OSBs that use urea-formaldehyde as a binder often emit gasses that contain formaldehyde, a very toxic material.
Can you make OSB smooth?
You cannot achieve a smooth surface on OSB. Because OSB does not sand down smoothly, you will not be able to bring down the texture with sanding after painting. Sealing the Edges: OSB’s cut edges are susceptible to water infiltration.
Can you use screws on OSB?
Screws – and DO NOT use drywall screws. Use coarse thread coated deck screws 1 5/8″. OSB will pop the head off a drywall screw, even with a drywall screw bit on the drill. And the fine thread on a drywall screw will not hold in a joist – it will spin and strip the threads when the head hits the OSB.
Can you use OSB on walls?
Oriented strand board (OSB) is similar in appearance to plywood, and both are suitable for hanging on exterior walls, a process typically called “boxing.” OSB is “structural,” meaning it lends strength to the house’s assembly when installed correctly.
Is OSB cheaper than drywall?
what should I cover my walls with? The two competing materials at this point are OSB and Drywall. The biggest reason is cost – 1/2″ drywall sheets are about the same price as 7/16 OSB (with 15/32″ OSB not far either).
Will termites eat OSB board?
Will Termites Eat OSB? Oriented strand board (OSB) is made of wood, but it is cement-bonded for extra durability. For this reason, termites aren’t likely to eat it. The presence of the cement works to deter termites from the cellulose in the wood chips which make up the board, but also prevents decay.
Is there anything cheaper than drywall?
Sheet Wood Sheet wood can be found in a variety of materials, like a medium-density fiberboard, oriented strand board, and plywood. It’s not only some of the cheapest products that can be used as an alternative to drywall, but it’s easy to install.
What OSB to use on walls?
Exterior Walls Minimum thickness to use on walls; 3/8″ plywood or 5/16″ OSB. If you are using fiber cement siding as a finish go with a min of 1/2″ plywood or 7/16″ OSB for the exterior walls.
Should OSB be installed vertically or horizontally?
If the height of a wall is less than 8-feet, install the plywood (or OSB) vertically. If the height of a wall is greater then 8-feet, install the plywood (or OSB) horizontally.
Can you waterproof OSB?
Step 4: Apply Waterproofing Coat your OSB pieces and allow the seal to dry for 12 to 14 hours. Now turn the wood and coat the remaining surfaces. If you need more layers of waterproofing for more protection, you can add them. Just allow each layer to dry for 12-14 hours before adding the next layer.
Is OSB dust harmful?
Ingestion: Not applicable under normal use. Symptoms or Effects: Acute Symptoms/Effects – Dust may cause mechanical irritation of the eyes and respiratory system. Dust can cause physical obstructions in the nasal passages, resulting in dryness of nose, dry cough, and sneezing.
Which side of OSB goes out?
For interior uses the OSB should be smooth side out. The reason it is textured on one side is for roofing purposes and states to install with that side up.
Which side of OSB paint is best?
Smooth side out. It makes dusting the walls much easier. I covered my walls in my shop in Colorado with OSB and had great results by using Kilz oil based primer and didn’t have any lifting or swell that you might expect from the water in Latex.
What size OSB do you use for walls?
Panel Dimensions When applying OSB sheathing to shear walls in a zone of seismic risk, the minimum recommended thickness is 15/32 inch.
Can OSB make you sick?
Acute exposure is irritating to the eyes, nose, and throat and subsequent exposures may cause allergic reactions of the skin, eyes and respiratory tract. Long-term exposure to low levels in the air can cause asthma-like respiratory problems.
Which is better OSB or plywood?
Wood fiber is used more efficiently in osb. Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists.
Which side of OSB should you paint?
For interior uses the OSB should be smooth side out. The reason it is textured on one side is for roofing purposes and states to install with that side up. You put a smooth side up on a roof and you are going ice skating. You can mix drywall compound with paint, or paint with drywall compound.
Why is OSB so expensive?
As well, input costs for wood panel products are much higher. A spike in demand, whether for immediate repair needs or longer-term rebuilding, for plywood and oriented strand board (OSB) always causes a surge in price.
