INSTALLATION Preparing and Fixing GTEC Cove Make sure the background is dry and rigid. Any wallpaper, whitewash, distemper or loose decorations should be removed. Brush over the surface to remove any remaining loose particles and dust. 1 Using a chalk line strike guidelines on the ceiling and wall to the correct projection and depth. 64mm for 90mm GTEC Cove 90 84mm for 120mm GTEC Cove 120 2 Using the guidelines on the wall, drive in the nails at 1500mm centres to act as a temporary support while the GTEC Cove Adhesive sets. 3 Using a fine-toothed saw cut all the pieces of GTEC Cove to length and mitre to fit the corners of the room. <strong>The</strong> mitres can be cut using a mitre block or template. Templates are included in this installation guide. Note: It is best practice to fit the longest lengths first and work in one direction around the room. If the room has a chimney breast start on the face of the chimney and work in one direction around the room. 4 Mix the GTEC Cove Adhesive as per instructions on the bag. Apply the adhesive to the back of the cove along its full length on the surfaces that meet wall and ceiling. 5 Sit the lengths of cove on the nails and press into position between the guidelines, carefully lining up joints and intersections. 6 Clean off surplus adhesive with a filling knife and smooth using a sponge. 7 Using GTEC Cove Adhesive fill any gaps between the cove and the wall or ceiling. Make good all internal and external junctions. 8 Remove all the temporary nails once the GTEC Cove Adhesive has set and fill the nail holes. 9 Using a damp sponge, clean off any adhesive residue from the walls, ceiling and cove surface. 10 Apply one coat of GTEC Universal Sealer, or if a vapour control layer is required use two coats of GTEC Drywall Sealer, and decorate as required. 1 2 3 4 Cover image courtesy of Bovis Homes 90 THE INSTALLATION HANDBOOK 2008
