Name both surfaces and whether either is absorbent, then check load direction, moisture, movement, temperature, cure time and removal needs against the current technical data sheet.
Scope: Confirm substrate, load direction, edge distances and maker data; safety-critical or structural fixings need competent design.
Four options to compare
What kind of bond are you trying to make?
1
Porous interior mounting
Best for: Supported trim or fixtures where at least one surface can release moisture from a water-based adhesive.
Main trade-off: Non-porous pairs, damp areas and early loading can prevent a reliable cure.
Must check: Both materials, absorbency, initial support and full cure time.
2
Mixed-material interior or exterior
Best for: Documented material pairs exposed to greater moisture or temperature change.
Main trade-off: Broader compatibility does not mean every plastic, coating or load is supported.
Must check: Technical data sheet exclusions, movement, exposure and service temperature.
3
Contact bond
Best for: Appropriate surfaces needing high initial contact strength.
Main trade-off: Open time, alignment and solvent compatibility can make it unforgiving.
Must check: Application to one or both faces, ventilation, open time and repositioning window.
4
Mechanical fixing or removable method
Best for: Critical, overhead, high-leverage, valuable or future-access installations.
Main trade-off: The result may be more visible or slower to install.
Must check: Whether adhesive failure or removal damage would be unacceptable.
Write down the material pair
“Wood to wall” is not precise enough. Identify the coating, board or masonry surface, porosity and condition on both sides.

Porosity and preparation
Load direction and temporary support
Moisture, movement and temperature
Use the exact product sheet
Family names often cover several chemistries. Confirm the exact variant, pack and current technical data before treating two listings as equivalent.
