Comparison

Contact adhesive vs Spray adhesive: which should you use?

Both bond large flat areas. One is permanent and unforgiving, the other is light duty and often repositionable.

The short answer

Contact adhesive when the bond must be permanent and take some load: worktops, laminate, veneer. Spray adhesive for light, large-area work where you need to reposition or where the load is nearly nothing.

Choose Contact adhesive when

Laminate to substrate, veneer, leather, rubber sheet. The joint takes shear load. It has to last for years and never let go.

Choose Spray adhesive when

Mounting paper, card, photos, fabric, foam or insulation. You want to lift and reposition. Overspray is acceptable and the weight is negligible.

What actually separates them

Contact adhesive is applied to both faces, left to touch-dry, and grabs permanently on contact with no adjustment at all, which is why people ruin worktops with it. Spray adhesive is the same idea diluted: far weaker, sometimes repositionable, and no water resistance to speak of.
