Drywall joint compound may temporarily stick to plywood, but will be unlikely to remain attached to plywood for a prolonged period of time. Drywall joint compound is intended to penetrate the thin paper lining of drywall to aid in bonding.
Does joint compound adhere to wood?
Acceptable Types of Wood 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.
Can joint compound be applied to plywood?
Drywall compound, often referred to as joint compound or “mud” in the contracting trade, is a thick white paste used as a sealant for interior surfaces. Though most commonly used to patch seams between sheets of drywall, mud can be used on plywood to create a smooth, professional finish.
Can I patch drywall with plywood?

Can you dot and dab onto plywood?
I would advise against dot and dab adhesive as it’s simply not intended for that application. You could use a grab adhesive but I would advise against that also. I’d do as Tigercubrider suggested and use a mechanical fix and you could use a polythene sheet to act as a vapour barrier.
Is polyfilla OK for Wood?

How do you fill seams in plywood?

Can you plaster straight onto wood?
It is not advised to plaster directly onto a wooden surface as wood is too porous of a material to hold a bond with the PVA primer and plaster layers. Another way to plaster over wood would be to disrupt the surface.
Does joint compound stick paint?
You use drywall joint compound for almost all drywall repairs. Unfortunately, it doesn’t stick well to gloss or semi-gloss paint. Not only does it cut grease and dirt, it etches the finish and improves paint adhesion. Chip off any loose drywall mud on seams from which the paper is separating with a paint scraper.
Can you tape plywood?
Mesh Tape. Mesh tape can be applied to a small area of plywood, such as the overlap between a piece of drywall and a piece of plywood. The tape will give the joint compound more of a purchase on the wood, and will help prevent cracking and flaking as the compound dries.
Can I use normal filler on wood?
No problem using polyfilla, as long as the wood will have a painted finish. No problem I’ve been doing it for years, as Steve says if it’s being painted over. Just make sure you rub it down flat with surrounding surface and fill and holes that usually appear after you’ve packed the stuff away.

Does spackle stick to plywood?
The plywood surface cannot absorb the spackle compound like the outer surface of drywalls. Usually, the plywood surface is composed of multiple layers of wood fiber and veneer or other finishing compounds. These serve as natural deterrents for the spackle compound to be imbibed within the plywood surface.
Is plywood better than plasterboard?
Drywall is much better than plywood when it comes to being fire resistant as it does not burn as fast or catch on fire as easily. Plywood is simply wood, when faced with a house fire, plywood walls go up quickly.
Can you skim coat plywood?
