The biggest problem with using concrete in your shower is the materials porosity. Concrete is very porous by nature, which allows the absorption and passage of water through untreated concrete. Therefore, it is important to properly seal your concrete showers, baths, and sinks with a high quality concrete sealer.
There are two options when it comes to sealing a concrete shower or bath. A natural finish, penetrating sealer or a durable concrete coating.
If you are not looking to change the look or appearance of the concrete shower or bath, a penetrating concrete sealer is going to be an excellent choice. The Siloxa-Tek 8510 is the deepest penetrating, highest performing and longest lasting penetrating concrete sealer. Comprised of almost 100% actives, it is able to reduce moisture seepage and prevent mold and mildew growth. This proprietary {silane/siloxane} concrete sealer dries completely clear and three or four wet-on-wet coats are required for optimal protection. Let the Siloxa-Tek 8510 fully cure for at least 24 hours before taking a shower or running the shower/bath water.
Penetrating concrete sealers leave natural finishes so the concrete will not be slippery when wet.
If you are looking to aesthetically enhance the concrete shower or bath with a decorative sheen, or if you are looking to change the color of the concrete shower or bath completely, a durable concrete coating like the Wear-Tek 4400 is the product to use. The Wear-Tek 4400 is a durable coating that will not delaminate, peel or yellow. It will also make organic growth easy to clean and will keep water from seeping through the concrete itself. It can be slippery when wet so a matte additive can be added at the time of application to bring down the sheen or a slip resistant additive can be used to increase traction.
