Fundo Primo

Product information

The wedi Fundo Primo Shower System offers full warranty coverage like all wedi Shower Systems, thanks to its complete and natural waterproof core, and it’s range of specially engineered components. Fundo Primo is internally waterproof due to its wedi XPS foam‘s closed cell structure, and naturally protects against mold or mildew like every wedi XPS foam based product.

It is fast and clean to cut to fit custom designs while prefabrication reduces installation time significantly. The base features a strong and pre-sloped surface, allowing for tiling immediately whether you choose mosaic or large format tiles. The wedi Fundo Primo is primarily made to work in shower designsincluding a wedi curb.

Pre-sloped extension panels are available so that no limit exists for creating any size or shape for custom shower designs. Fundo Primo is insulating, creating a thermal barrier that can prevent cold from transferring through the tiled surface, and make floor heating systems more efficient. It also has outstanding moisture and water exposure control compared to traditional mortar bed installations or other currently known methods for building showers, including the use of sheet or liquid waterproofing membranes which can be very thin and vulnerable, or they may offer water absorption into thin-set bonded seam areas.
