Elastoproof Prefabricated External Corner - CN270 - Pack of 10

Elastoproof Prefabricated Corner Sections are designed to simplify and enhance the waterproofing capabilities of Elastoproof Jointing Band applications at crucial 90° and 270° corner intersections. These prefabricated corners create a seamless, flexible zone, ensuring a watertight and elastic seal even when exposed to movement and vibration.

Key Features

• Creates a seamless elastic seal at joint intersections
• Waterproof and acts as a vapour barrier
• Fast and efficient installation
• 100% elastic recovery when exposed to movement
• High strength and excellent tear resistance
• Provides long-term sealing protection in vulnerable areas
• Eliminates the need for lapping and bonding of fabrics at corners
• Compatible with all Gripset membranes

Uses

• Detailing 90° and 270° corners in waterproofing applications
• Creating watertight seals around windows, doors, and other penetrations
• Protecting joints in balconies, terraces, and other exposed areas
• Enhancing the durability of waterproofing systems

Benefits

• Simplifies the waterproofing process, saving time and labour
• Provides a superior alternative to traditional corner detailing methods
• Ensures long-lasting protection against water and vapour ingress
• Improves the overall integrity and performance of waterproofing systems
• Reduces the risk of leaks and water damage

Application Guide

1. Apply a generous coat of Gripset membrane to the surface, covering the entire rear corner profile.
2. Embed the corner profile into the wet membrane, ensuring all fabric edges are fully saturated.
3. Smooth out any creases or air pockets behind the fabric edges using a flat spatula or brush.
4. Remove excess membrane from the top surface of the corner.
5. Overlap and adhere Elastoproof Jointing Bands onto the prefabricated corner sections with a minimum overlap of 40mm using the selected Gripset membrane.

Limitations

• Not compatible with solvent-based materials (adhesives, sealants, coatings)
• Do not apply when the surface temperature is below 5°C or above 30°C

Packaging

• Internal 90° corners: 200mm x 200mm with 120mm wall/floor returns
• External 270° corners: 200mm x 200mm with 120mm wall/floor returns

Precautions

It is recommended to test the adhesion of all products (primers, membranes, coatings, adhesives, etc.) on a typical area of the prepared surface before full application to ensure satisfactory adhesion. For large commercial areas or unusual substrates, Gripset Industries offers a pre-testing service. Consult Gripset Technical Services for further information.
