Key Takeaways:
- Gravity Dictates Choice: Use the liquid formula for flat, horizontal surfaces where the adhesive can spread easily. Switch to the gel formula for vertical or overhead tasks to prevent drips and runs.
- The 10-Minute Rule: You must allow the solvent to evaporate for 10 minutes after application. If you press the parts together while the adhesive is still wet, the bond will fail.
- Pressure Over Time: The strength of a contact bond is determined by the amount of pressure applied, not how long you hold it. A very firm press for 5 seconds is more effective than a light hold for several minutes.
- Precision is Vital: Contact adhesives bond instantly on contact. You cannot reposition the pieces once they touch, so ensure your alignment is perfect before the surfaces meet.
Master the Soudal Contact Adhesive Range
Contact adhesives provide a powerful, permanent bond for materials like wood, rubber, leather, and plastics. Soudal offers three specialised formulas to ensure the best results for every application. Unlike standard glues, contact adhesives are applied to both surfaces and allowed to dry slightly before joining.
Choosing the Right Adhesive
- Contact Liquid: Best for horizontal applications and large flat areas. It spreads easily for even coverage.
- Contact Gel: Ideal for vertical applications. The non-drip formula stays in place on walls or furniture sides.
- Contact Transparent: Perfect for transparent applications. It leaves a clear finish that is invisible on glass or clear plastics.
Step-by-Step Application Instructions
- Clean the Surface: Ensure both surfaces are completely dry and free from dust or grease.
- Apply the Adhesive: Use a brush or spreader to apply a thin, even layer of adhesive to both surfaces being bonded.
- Wait for 10 Minutes: Allow the adhesive to sit. The solvent needs time to evaporate until the surface feels tacky but does not transfer to your finger.
- Press Parts Together: Carefully align the pieces. Once they touch, they will bond instantly.
- Apply Firm Pressure: Press the surfaces together firmly for at least 5 seconds to set the bond.

FAQs
- Can I move the pieces after they touch? No. Contact adhesive creates an immediate bond. We recommend marking your alignment points before you join the two surfaces.
- What happens if I don’t wait 10 minutes? If the adhesive is too wet, the trapped solvent will prevent a strong bond. Always wait until the glue is tacky before pressing the parts together.
- Is the bond heat resistant? Soudal contact adhesives offer excellent resistance to moisture and heat once cured. For specific temperature limits, please check the product’s individual Technical Data Sheet.
