Select the Gripset Betta membrane to be used for the waterproofing application. Surface must be clean, refer to instructions of the Gripset Betta membrane being used to ensure surface is correctly prepared.

Select correct Gripset Betta primer for the application and prime surface as per instructions on the primer label.

Once primer is dried, apply a liberal coat of the Gripset Betta membrane to the surface, ensuring enough membrane is applied to cover 100% of the rear corner profile. Note – Aim for a minimum 1.5 mm wet film of membrane to be applied to the surface.

Embed the corner profile into the wet membrane bed, ensuring the fabric edges of the corner are fully wetted into the membrane film. Using a flat spatula or brush, ensure all creases or air pockets behind fabric edges are pushed out. When applying, ensure enough wet membrane is applied behind the corner otherwise proper adhesion will not be achieved. Note – Corner must be bedded into a wet film of the membrane. Do not allow membrane to skin or dry before bedding corner in position. When applied, the corner should be tightly fitted into position, showing good adhesion to the surface.

Remove any excess membrane on the top surface of the corner by either brushing over the face of the corner or onto the surface.

Once this has been completed, Gripset Betta Elastic Joint Band is ready for installation.

Gripset Betta 270° Corner is available for outward facing profiles, e.g. corner intersections etc.
