Choosing the right adhesive is crucial for a successful rubber flooring installation. Use the wrong glue and you'll end up with lifting edges, failed bonds, or damage to your subfloor. This guide covers everything you need to know.
Types of Rubber Flooring Adhesive
1. Polyurethane Adhesive (Recommended)
The gold standard for rubber flooring. Creates a strong, flexible bond that moves with the rubber.
- Best for: Concrete, screed, plywood
- Cure time: 24-48 hours
- Coverage: 3-4m² per litre
- Pros: Waterproof, flexible, extremely strong
- Cons: Higher cost, requires ventilation during application
2. Contact Adhesive
Apply to both surfaces, wait until tacky, then press together for instant bond.
- Best for: Small areas, repairs, vertical surfaces
- Cure time: Immediate bond, full cure 24 hours
- Pros: Quick, strong immediate bond
- Cons: No repositioning once contact made
3. Pressure-Sensitive Adhesive
Stays tacky permanently, allowing removal and repositioning.
- Best for: Temporary installations, rental properties
- Pros: Removable, no damage to subfloor
- Cons: Not as strong, may shift under heavy loads
4. Double-Sided Tape
Simple solution for mats and loose-lay tiles.
- Best for: Gym mats, temporary flooring, small areas
- Pros: Easy application, removable
- Cons: Limited strength, not for permanent installation
Adhesive by Subfloor Type
| Subfloor | Recommended Adhesive | Notes |
|---|---|---|
| Concrete (dry) | Polyurethane | Prime dusty concrete first |
| Concrete (damp) | Epoxy moisture barrier first | Must treat damp before fitting |
| Plywood | Polyurethane or contact | Ensure plywood is sealed |
| Existing tiles | Flexible tile adhesive | Degrease thoroughly first |
| Metal | Contact adhesive | Abrade surface for better grip |
Application Tips
- Temperature matters - Apply between 15-25°C for best results
- Use a notched trowel - Creates even coverage and correct thickness
- Work in sections - Don't spread more than you can lay in the open time
- Roll after laying - Use a heavy roller to ensure full contact
- Clean excess immediately - Most adhesives are difficult to remove once cured
How Much Adhesive Do I Need?
Typical coverage rates:
- Polyurethane: 3-4m² per litre
- Contact adhesive: 4-5m² per litre (per coat, both surfaces)
- Double-sided tape: 1 roll per 10-15m² perimeter
Common Mistakes to Avoid
- ❌ Using too much adhesive (causes oozing and longer cure times)
- ❌ Not allowing proper cure time before use
- ❌ Applying to damp subfloors
- ❌ Not testing adhesive compatibility with rubber type
