Valley with metal valley gutter The valley is covered with an underlaid metal valley gutter usually with a deep profile. The depth of the valley gutter must be at least 20 mm. An adequate support must be in place in the vicinity of the valley for the positioning and fixing of the diagonally-cut fibre cement panels. The valley gutter sheets must lie fully on a substructure. To protect the valley gutter from corrosion, it is recommended that e.g. bitumen sheeting is inserted beneath the metal sheeting. Measured perpendicularly to the direction of the valley, the overlap b over the valley gutter must be at least 200 mm with a roof pitch ≥ 7° and at least 150 mm with a roof pitch ≥ 26°. The overlap of the panels in the valley gutter should be at least 50 mm.

Luko edge sealant is an emulsion and must be stirred/shaken prior to use. The Luko edge sealant can be kept for 6 months from the fill date. Immerse the applicator, with its special 5 x 8 cm microfibre sponge, in the application trough containing the sealant. The Luko 803 edge sealant is used neat. Run the applicator across the raised edge in the container to prevent the sponge from dripping and enable the excess emulsion to flow back. The working temperature is +5°C to +25°C; storage temperature -10°C to +25°C. Only seal panels individually, not in a stack. As the applicator is drawn along the edge of the panel it should be inclined slightly towards the rear face to prevent residues of the sealant from showing on the visible face. Wipe away any visible excess sealant on the edge of the panel immediately with a cloth. Dirt on the surface must be removed immediately. If there is any Luko 803 edge sealant left in the application trough, do not return it to the main container or reuse it at a later date. It should be renewed after treating around 200 cut edges. The sealant should be stirred occasionally during use. The Luko 803 edge sealant must cover the edge completely. Sufficient coverage can be seen if the whole surface of the edge is shiny. Any thickened or hardened residues can be disposed of with the household waste. The sponge can be reused several times provided it is cleaned immediately after use.
