Ensure that the aperture and services in question are tested with Stopseal Linear Gap Seal and that the site conditions are within the application specification. Sufficient space needs to be present to allow for an acceptable installation method.
Measure the void to be filled to ensure the correct size of Stopseal Linear Gap Seal is being used.
Clean the surrounding area so that it is free from dust. For trunking boxes tie any loose cables so that they form a tight bunch.
Compress seal between fingers and press into place. Slide in to place to ensure a snug fit to the surrounding building element or trunking. Ensure that core recovers and edge of the seal is flush with the face of the joint.
Seal can be cut easily with a Stanley knife to give correct fitting length.
