Step 3 – Keep a check on the Shower Floor

The Ligno shower system requires you to sink the tray into the shower floor. If you also face the same situation, then you are supposed to cut a hole in the shower floor.

This floor is made from OSD (Oriented Strand Board). Craft a perfect required square size that is appropriate for your shower tray, then you are supposed to create a platform.

To do this, Inspect your floor and remove any floor bumps or nails and then screw plywood on the top to create a base.

Slip the OSD sub-floor back in its place and then cut a hole in your drain. In case you are Using KBRS, it is not necessary to have your tray lower than the shower floor, so you can skip the previous step and direct forward to cutting a hole.

Apply primer on the drain parts. It makes fusion better. Add sealant around the drain, then push the drain into place. Tighten the nut and you are good to go after pressing it for few minutes till sealant dries.

Step 4 – Apply A Layer Of Thin-Set

Clean Your floor carefully and properly. Use a knife to spread an even layer of thin-set onto sub-floor, then bail it. Collect the extra thin-set which gets spilled on the floor and then try to minimize the uneven floor of air pockets. Install your shower walls now.

While using a Ligno, your shower tray will have channels on it, slip the panels and put them into place and put pressure on them and while using KBRS, use a drill to screw panels into their respective places.

Step 5 – Make Arrangement For Your Shower Curb

KBRS showers come with a convenient self-sealing curb, cut out curb for the exact fitting size. Use a caulking gun to apply sealant on the shower-facing side of the curb. On the bottom side, apply thin-set to glue it to the floor. Make sure there are no leakages. Let it dry and after that remove all excess sealant and fix slopes, if found any.

If you decide to install a shower curb, buy the right kind. KBRS is ideal because it’s effective against rotting and is crafted of two materials. Its closed-cell technology means it ‘wraps’ itself around screws and shower doors, instantly filling gaps that could let water sweep.

Step 6. Paint On The Waterproofing Materials

You can use either cement tape to waterproof your corners or use the fiber mesh included in your KBRS kit. Use a paintbrush, apply a coat of liquid waterproofing everywhere, joint, corner, put tape on top of the gel, then paint another layer on top to hold the fabric.

Let the Liquid dry for an hour. After it dries properly second coat. When it’s complete and let it dry, fill the shower floor with water and let it dry for more than an hour to test leakage, this procedure is called a flood test.

Make sure to fill all the gaps if any left,
