Usage:
SikaDur® 30 is used for:
- Bonding and Repairing Concrete and Masonry: Ideal for repairing cracks, joints, and spalls in concrete or masonry surfaces, restoring their strength and integrity.
- Surface Protection: Applied as a protective coating on concrete surfaces to enhance durability, protect against abrasion, and resist chemical and moisture ingress.
- Structural Repair: Used to bond reinforcement steel bars, patch and repair damaged concrete elements, and improve the load-bearing capacity of structures.
- Floor Coating: Used as a protective coating for concrete floors in industrial facilities, warehouses, and commercial buildings to resist mechanical wear and chemicals.
- Sealing Joints and Cracks: Seals joints and cracks in concrete surfaces to prevent water ingress and maintain structural integrity.
Advantages:
- Excellent Adhesion: Provides outstanding adhesion to concrete, masonry, stone, metal, and other common construction materials, ensuring a reliable bond.
- Fast Curing: SikaDur® 30 has a quick curing time, allowing for rapid project completion and minimizing downtime for construction and repair tasks.
- High Durability: The product forms a tough, durable coating that withstands wear, abrasion, and exposure to chemicals, making it ideal for industrial and commercial environments.
- Moisture and Chemical Resistance: Offers excellent resistance to moisture, chemicals, and oils, protecting surfaces in demanding environments such as factories, warehouses, and outdoor structures.
- Versatile Application: Suitable for use on both horizontal and vertical surfaces, as well as overhead applications, making it highly versatile for different types of repairs and coatings.
- Non-Shrinking: As it cures, SikaDur® 30 does not shrink, ensuring the repaired areas maintain their strength and integrity over time.
- Long-lasting Performance: Once cured, it provides long-lasting protection, reducing the need for frequent repairs and maintenance.
Application:
- Surface Preparation: Ensure the surfaces to be bonded are clean, dry, and free from contaminants such as dust, grease, oil, dirt, or loose particles. If necessary, roughen the surface for improved adhesion.
- Mixing: Sikadur® 30 comes in a two-component system, consisting of a resin and a hardener. Mix the components in the recommended proportions (typically 1:1 by weight) until a uniform consistency is achieved.
- Application: Apply the mixed adhesive to one of the prepared surfaces using a brush, trowel, or other suitable tool. For best results, ensure even coverage and contact between the two surfaces.
- Bonding: Press the two surfaces together immediately after applying the adhesive. Ensure there are no air pockets and the bond is consistent.
- Curing: Allow Sikadur® 30 to cure for at least 24 hours under standard temperature conditions (longer curing times may be necessary at lower temperatures). Full bond strength is typically reached after 7 days.
- Inspection: After curing, inspect the bonded areas for any gaps or weak points. Ensure the bond is solid before subjecting it to any load or stress.
Coverage:
Sikadur® 30 is a high-strength, two-component epoxy adhesive designed for bonding and repairing concrete, masonry, and stone surfaces. The coverage varies depending on the application method and thickness, but typically 1 kg of Sikadur® 30 covers about 0.5 to 0.7 m² at 1 mm thickness. For larger bonding areas, the actual coverage may depend on the surface texture and conditions.
