Product
Soudal Soudal Cork Adhesive
Water-based dispersion paste for interior bonding of cork tiles, rolls, and sheets to porous surfaces.
This is grab adhesive, no-nails, so everything true of that chemistry applies here too.
Specification
- Form
- Paste
- Working time
- 25 minutes
- Full cure
- 12 hours
- Service temperature
- -20C to 80C
- Water resistance
- Water resistant
- Application temperature range
- 5 °C to 30 °C C Manufacturer verified
- Full cure time
- 12.0000 hours (Soudal state this as drying time, not separately as time to full strength) Manufacturer verified
- Maximum service temperature
- 80.0000 C (Upper end of the stated temperature resistance range) Manufacturer verified
- Minimum service temperature

- Manufacturer substrate wording
- concrete, wood, stucco, stone (All four are porous. The adhesive is a water-based dispersion and cures by physical drying, so it needs a substrate that lets moisture out) Manufacturer verified
- Water resistance wording
- Soudal's word is "Water resistant", listed as a product property. The datasheet makes no waterproofing or immersion claim, and separately warns "Never install on a subfloor with too high moisture content." (Properties bullet only. Not a waterproof or immersion rating) Manufacturer verified
- Working time
- 25.0000 minutes (Stated as approximate; varies with temperature, humidity and substrate absorbency) Manufacturer verified
What it bonds
Where the manufacturer names a material, we quote them. Where we have assessed it ourselves, we say so and grade it lower. The two are never merged.
| Material | Basis | Manufacturer wording |
|---|---|---|
| Concrete | Listed by the manufacturer A | “concrete, wood, stucco, stone” |
| Cork | Listed by the manufacturer A | “cork based materials (tiles, rolls, sheets)” |
| Natural stone | Listed by the manufacturer A | “concrete, wood, stucco, stone” |
| Plywood | Implied by the manufacturer B | “concrete, wood, stucco, stone” |
| Plasterboard | Our assessment: suitable with care C | The manufacturer names porous surfaces and plaster, not paper-faced plasterboard; use only on a sound porous face after a coupon test. |
Preparation
The surface must be rigid, clean, dry, free of dust and grease. On very absorbent surfaces the surface should be treated with a primer. Never install on a subfloor with too high moisture content.
Limitations
Interior use. Water-based dispersion, so it needs a porous or otherwise breathable substrate to dry through. Water resistant is Soudal's own wording and carries no immersion approval.
