Making A Wet Room Floor Using Screed

Fill in any voids.

Making a wet room floor using screed.

A retro fit wet room will require the old screed to be removed in the designated shower area to allow the new drainage system and screed to be installed with the required drainage falls. When you invest in a wet room you need to be confident that your final floor is completely waterproof before a single drop of water hits it. Once the matrix is fully put together fit the floor drain central dish and protective trap before filling with screed. If the floor level of the wet room cannot match the room it is entered from consider what sort of a join will be used and how this works practically.

Your bathroom floor is most likely to be concrete screed or floorboards. If a step up or down is required it is best to have one 10cm step or higher instead of multiple steps measuring between 3 and 4cm which could pose a trip hazard. Begin to apply the fairly wet mixture making sure that the screed is well packed into the matrix sections. In a new build the wet room drainage systems are installed into the floor prior to the screed being laid.

Water will find its way to the lowest level at any angle of fall. There is no need for a steep slope to the floor. Assemble and fit the remaining colour sections ensuring that each part is level along its length as you go. If you have floorboards then check that they are clean dry and firm screw down any that are loose.

At longfloor our liquid cement screed offers total peace of mind once laid and finished with the final flooring coverings of your choice. This could be part filled with a normal screed and then finished with microcement to create the finished floor layer. Stick a waterproof membrane to the floor with a flexible thin bed adhesive. Level across the screeds using your spirit level or a straight edged piece of timber moving the mix around until it is absolutely level between your two screeds.

Rub the covering to a void free finish with the float. The entire room is tiled from floor to ceiling and the natural gradient of the floor directs water to the drain. If you use an open floor plan approach to for example your kitchen and dining area then the wet room is in the same line of reasoning. This is to create the required gradient needed for the wet room floor.

Fitting a horizontal waste trap to a wet room floor the channel housing the drain is then concreted over and a fall is constructed into the floor by using a self levelling floor compound thickened slightly with sharp sand.
