1. Measure and cut strips to length. Mitre cut corners.Square cut ends (refer to last paragraph). 2. Remove saw cut frays with a blade. 3-5. Notch each mitre cut with a snips or blade to form a square hole through meeting strips.Test strips in position to ensure they fit correctly. 6-7. If outer strip edge is not resting on the ledge, score the strip with a blade and tear off removable inside leg.
8. An adhesive fixing of the strips to the wall (see 17-18) may be strengthened with a mechanical fixing (screw/nail) if the weight of the wall panels is likely to dislodge freshly adhered strips because the adhesive/sealant has yet to cure. This is not an issue where panels are supplied in the form of lengths but to be considered if wall panels are supplied in sheets. 9-10. If corner trims are being installed, notch corner trim flanges so trim end rests on strip.
11. Wipe ledge with alcohol wipes. 12. With pencil and small strip off-cut, lightly mark where strip outer edges rest on ledge (4 points/side).
13-14. Insert first strip (middle strip if any) upside down into 2 mitre boxes (or similar support). Resting nozzle in strip, lay a 400mm line of Sealux-N inside the profile. Level Sealux-N across the strip with spatula. Redistribute or add sealant as required. Repeat process in 400mm steps until complete. Butter strip ends flush slightly proud with Sealux-N.
15. On ledge to receive the first strip, using finger under nozzle as support and fingertip against wall as guide, lay an 8mm line of Sealux-N on the ledge inside the strip outer edge pencil marks. 16. Lay a 5mm line of Sealux-N roughly 15mm over ledge. 17-18. Rotate the first strip over the joint against the wall fusing the Sealux-N in the strip with the Sealux-N on the ledge. Fix first strip to wall. Remove surplus sealant (if any) off ledge with the square corner edge of spatula.
19-20 Repeat the same procedure for remaining strips. During installation butter each mitre cut slightly proud with Sealux-N to ensure sealant fuses across (inside) meeting strips. 20. Apply Sealux-N into notches at corners.
21-22. Address the preparation and installation of wall panels and wall trims as specified by supplier. After panels and wall have been prepared and surfaces made ready for the panel/wall bonding process, lay a line of Sealux-N across the respective strip upstand as shown.
