GURU WATER-STOP BOARD 3' x 5' x 1/2" (Pack of 6)

Fast and convenient, the GURU W-S BOARD reduces drastically the building time of a shower by having a WATER-STOP layer factory-bonded to a XPS foam.

Guru's W-S BOARD is a wall board shower construction panel with waterproofing included for tile coverings, perfect for waterproofing or building new showers spaces. It can be installed on wooden structures or metal profiles for drywall partitions (plasterboard type) to create a new partition or on the existing partitions themselves to level the irregularities of the walls for the subsequent installation of ceramic tiles and also to waterproof. Another of its most common uses could be for renovations or reforms, installing the panel directly on the old ceramic to later install the new coating on a completely smooth, plumb and uniform surface. 

Composition of the wall board W-S BOARD
The wall board W-S BOARD is composed of an extruded polystyrene foam panel bonded to the WATER STOP waterproofing sheet to achieve a total bond to the tile adhesive. In case you want to adapt the panel to a specific size or dimension, you can simply cut it with a cutter or similar, without losing any of its properties. The grids, printed on the outside, are very useful for cutting and laying the panels quickly. Ceramic tiles are installed directly on W-S BOARD by applying a thin layer of tile adhesive.

Drywalls for showers: Installation modes
As mentioned above, the W-S BOARD drywalls building panels can be installed both on wooden structures and on the walls themselves, the installation of both being different:

Installation on wooden structure or panels
In this type of installation we will fasten the panels to the structure with screws and washers that you will find in our Fastener Kit. This kit has an anticorrosive protection in all its parts. For the installation to be completely waterproof, the screws should be coated with some type of sealing putty such as W-S MASTIC. In wall installations the screws are placed every 11-12″ vertically and every 5-6″ horizontally. On the other hand, in ceilings they should be installed every 2-3″ vertically and horizontally.

Installation on building walls
When it is going to be installed on building walls or on an old installation, a glue cement base type C2 or monocomponent, such as our Easeal, should be used to fix the panels and to standardize the possible unevenness or flaws that may exist.
