How to Install a Shower Waterproofing Membrane

Waterproofing membranes are used in a number of ways for waterproofing purposes in both commercial and residential properties. These waterproofing membranes can often be found in locations such as homes, water tanks, hospitals and commercial buildings. Waterproofing membranes may also be used for roofs as well. Waterproofing membranes come in a various of options so that they can stand up to the elements and daily wear and tear where appropriate.

If you are considering installing a waterproofing membrane in your shower, there are a few simple steps that you need to follow. Here are the materials and steps required to get the job done.

Start by figuring out what materials will be required. You will need the membrane, waterproof sealer, a roller, a hot air gun and preformed corners. Check the shower area for any sharp objects such as nails. If you find these items, go ahead and remove them. Otherwise use a sander to get rid of them if you have trouble removing them. Finally, clean the area in which the membrane will be applied in the shower.

The substrate material should then be applied so that it levels the walls and the floor. A membrane should never allow water to settle and should be applied so that it slopes downward allowing the water to flow into the drain. The waterproofing membrane should then be applied to the shower and cut according to the number of upturns that are required.

Carefully fix the waterproof membrane to the showers corners by using the preformed corners that you have already created. The membrane should then be placed on the way in a process that bonds the membrane tightly to the walls. The hot air gun can be used to flatten the membrane.

The shower pan should be applied after the area has been tested for leaks. A simple test can be done by first cleaning the membrane and then turning on the water until it fills the floor. Make a mark of the level of the water using the marker. Then leave and wait until the next day to return and note if the water level is any lower. If the water level is lower, that means that there is a leak and another membrane should be applied in order to deal with the leak issues.

Once these steps are complete, adhesive should be added to the membrane. Allow 24 hours and then return to apply the drain using a sealer on the edges of the drain.
