Can you finish OSB board?
OSB boards can definitely be directly finished with attractive results – but not all OSB is created equal! Virtually all coating products that can be used on solid wood can also be applied to sanded OSB. They include varnishes, oils, waxes and glazes, as well as water-based and natural paints.
Can you put drywall mud on OSB?
You can apply drywall mud to any rough-grain wood surface. Plywood or oriented strand board (OSB) are good choices, but the mud will also stick to painted wood, as long as the paint is flat and not glossy.
How do you texture OSB walls?
Using the Roller Method Cover the floor with the drop cloths. Put half the mud in a bucket and slowly add water, mixing it with the ribbon mixer, until it has the consistency of a milk shake. Pour the watered-down mud into a roller pan. Start rolling the mud onto the walls in a corner and work your way around the room.
What do you seal OSB board with?
Sealing OSB. For cases where OSB is more likely to be exposed to moisture, it’s a good idea to coat the OSB on the surface and edges with a waterproofing product, such as Thompson Water Seal, Flex Seal, or Liquid Rubber’s waterproofing sealant. Even latex paint will work.
How do you make OSB smooth and shiny?
If you want to smooth down the surface and edges, apply a resin filler coat with a putty knife. Apply it as thinly as possible. After the resin has dried (about 20 to 30 minutes), sand down the board and the edges with 220-grit sandpaper.
Can you varnish OSB?

Can I polyurethane OSB?
Because of the rough surface of OSB, you will most likely want to finish with a polyurethane coat, which will be extra work, but not only will it be heavy-duty, it will look incredibly glossy and clean with a smooth top. The polyurethane will also be important in the rooms with moisture.
Should I stain or paint OSB?
OSB (oriented strand board) is similar to plywood and used primarily for subfloors, covering exterior wall studs and roofing. It is not usually stained or painted, but that doesn’t mean that it can’t be done. OSB used for interior and exterior projects will accept stain and clear coat sealing products.
Why is there OSB behind drywall?
As previously stated by others, drywall has zero structural resistance to loads; therefore, another material (OSB or dimensional lumber) must be secured to the wooden or metal studs forming the wall. Once in place, any anchor used for the fixture will now bite into a more structurally sound material.
Can you mud over particle board?
FILLING PARTICLE BOARD EDGES: It certainly needs to be painted, but more importantly, it needs to be fussed-up a little before you open the can of paint. The edges are the hardest part. You can use either spackling or dry-wall mud.
Can I use joint compound instead of wood filler?
Drywall mud is easy to apply and will fill holes, dents and scratches smooth to the surface. Mixing up a batch of mud is quick and easy, but use it only if you are planning to paint the surface, as drywall mud dries to a white finish and will stand out against the color and tone of natural wood.
How do you seal OSB walls?
To apply, soak the tip of the paintbrush in the sealer and brush it over the OSB board’s ends and surface. Ensure this process is repeated on both sides, and not just the areas where you made cuts. Coat your OSB pieces and allow the seal to dry for 12 to 14 hours. Now turn the wood and coat the remaining surfaces.
How do you finish particle board walls?
Particleboard requires oil-based paints because a water-based latex paint can cause the wood to swell. Remove the furniture from the room. Sand the surface of the particleboard with a fine-grit sandpaper until the wall feels smooth to the touch. Vacuum the wall with the dusting attachment to remove any sanding residue.

How can I waterproof OSB?
It will take about 12 to 14 hours for the waterproofing to dry. To ensure that the OSB is waterproof pour some water on the OSB piece and wait for a few hours. If the water is not soaked then the OSB pieces are now waterproof.
