Gluing Cork
Cork tile, sheet, board, coasters and flooring.
Also called cork board, cork tile.
How Cork behaves when you bond it
Cork accepts spreadable adhesives well, but a low-viscosity adhesive can soak in and leave a starved bond line. Heavy point clamping can crush the material. Contact systems are useful for broad areas because they give immediate contact without sustained high clamping force. Water-based systems need at least one route for water to leave the joint.
Cork is a cellular bark material used either as natural sheet or as granules pressed into agglomerated board. Its surface is porous and can be dusty, while the body compresses easily. Density, binder, backing and factory-applied finish vary widely, so an adhesive that works on unfinished cork may not work on a sealed tile.

Surface preparation
Acclimatise tiles or sheet as their manufacturer directs. Make sure both surfaces are sound, dry and free of dust, wax, oil and loose particles. Use a uniform coat and even roller or platen pressure rather than narrow clamps. Prime a friable or very absorbent backing, or apply the extra coat specified by the adhesive maker. Check whether a painted, sealed or pre-finished face needs a different adhesive, as Soudal makes this distinction for pre-painted cork tiles.
Which adhesives work on Cork
Good
Contact adhesive
A contact system gives broad, immediate contact without sustained clamping that could crush cork. 3M PB920-Plus directly lists cork, but that product evidence must not be read as proof for every contact adhesive. Seal or recoat a very absorbent surface as directed.
Conditional
PVA wood glue
Unfinished porous cork can accept a water-based dispersion, but soak-in may starve the joint and water cannot escape readily if both faces are sealed. Use only where the product explicitly covers cork and the assembly can dry.
Conditional
Two-part epoxy
Epoxy can wet a clean cork surface and fill irregularities, but low-viscosity resin may soak in and a thick rigid bond line can concentrate stress in the weak cellular material. Use a thin controlled coat and light, even pressure after a test.
