Strait-Flex MEDIUM Composite Inside Corner Tape 57 mm × 30.5 m

Strait-Flex MEDIUM Composite Inside Corner Tape 57 mm × 30.5 m is a flexible composite profile designed for reinforcing and straightening internal 90° and off-angle plasterboard corners.

The profile is installed using standard plasterboard joint compound without nails, staples or special tools. Its composite construction helps produce straight, strong and professional internal corners while covering minor gaps and framing irregularities.

• Suitable for internal 90° and off-angle corners.
• Ideal for bay windows, vaulted ceilings and sloping structures.
• Durable composite construction.
• Helps conceal small gaps between plasterboard panels.
• Installs using standard joint compound.
• Slotted edges provide strong adhesion.
• Resistant to dents, shrinkage and common cracking.
• Will not soften or sag when wet.
• Rustproof.
• Does not fuzz during sanding.
• Easy to cut with scissors or a utility knife.

Application: cut the profile to the required length and fold it along the centre crease. Apply a liberal coat of joint compound to both sides of the corner. Press the profile into the wet compound, adjust it to form a straight line and remove excess compound and trapped air. Apply the finishing coats after the previous layer has dried.
