Watch our installation video to follow the fitting process. The dartry 2 tier wall panelling kit consists of moulded rails and stiles that come in loose components.Top mouldings are sold separately. This open backed kit does not have a back panel and so the exposed parts of the wall are painted in the the same colour as the kit so as to look as if the whole wall is panelled. If the wall surface was very rough you could place an mdf sheet on the wall first and then place the kit in front but in most cases this is not needed. These pieces are all moulded and when assembled form a panel, the material is 12mm moisture resistant mdf, the top mouldings are sold separately, skirting board is not included, this kit can be placed on existing skirting or used with new skirting, the kits are primed and sanded. The horizontal rails have a 45 degree chamfered mould, the stiles are premachined to correspond with this and fit into place, to adjust the height of the stiles on site, lean the mitre saw over 45 degrees and cut at the required height.
