It is fast and clean to cut to fit custom designs while the level of prefabrication reduces installation time significantly. The shower floor units feature a strong and pre-sloped surface which can be tiled over immediately whether you choose mosaic size or large format tile. Drain unit and drain cover set is always included with each Primo shower floor unit while further optional drain cover designs are available. Pre-sloped extension panels are available so that virtually no limit exists for making any size or shape for custom shower designs happen. The added values offered by Fundo Primo come in form of many more performance advantages. Naturally, Fundo Primo is insulating keeping surfaces warmer. Especially when compared to traditional mortar bed installations or other currently known methods for building showers such as those including use of sheet – or liquid waterproofing membranes used in an attempt to manage water exposure – wedi Fundo Primo's simplicity and high performance shows. The installation combines many manual and separate installation steps and materials usually needed into very few. Fundo Primo adds speed, safety and consistency to your installation: Measure, possibly cut, thinset to subfloor, connect drain – done. The most unique advantage, however, is the complete and natural core waterproofness of the wedi product and it’s completeness and range of components that will form an entire assembly system with Fundo Primo engineered to fit and last. A true system with full warranty coverage.
Cut the 2” pipe flush (or max. 1/8” above) to the floor construction. Make sure that the cut out fits to the Fundo panel drain. Cut out a 5” diameter hole around the 2” pipe to allow the wedi drain to be inserted into the subfloor while the cut out area must remain free of deflection. The drain and trap have to be sturdily fastened to the sub floor.
Weight is applied on and against the curb (from outside) and another 1/2” bead of sealant is applied over all curb seams and spread flat. The seams must be covered 1” either side of a seam. Curb connection notches must be cut to fit select Primo bases with perimeter thickness higher than 1 1/2”.
