By nature, the bathroom is a humidity-ridden and wet space. If you’re renovating your bathroom, avoiding waterproofing may save money in the moment, but it can lead to serious problems in the long run. Water dripping through the ceiling to the floor below, deteriorating tiles, peeling paint and mould are all realities of a bathroom that hasn’t been waterproofed.
To avoid these unwanted drips, leaks and other problems, it is important to waterproof your bathroom from the get-go or during a renovation project. Take care to properly waterproof your bathroom walls, floors and ceilings and for years to come your bathroom will continue to be the bathroom of your dreams!
Unfortunately, the most common waterproofing mistakes occur in the bathroom construction and preparation process. When undertaking a bathroom renovation, it is crucial that all surfaces are prepared and primed properly, and that special attention is paid to joints between walls and floors as well as around drains in the floor. Surfaces should be smooth, and the excess of dirt, grime or particles that may build up during the renovation process should be cleared away.
Homeowners may choose to install a polyester reinforcement mat into internal corners of the shower recesses, or alternatively a waterproofing membrane. A waterproofing membrane can be applied to all surfaces, two coats should be applied and the bathroom should not be worked on until this material has fully dried. The drying process could take up to 5 days, depending on the humidity of your climate.
Further, there are specifically trained waterproofing professionals who can assist in this renovation project, so ask for help if needed!

As gravity will force water downwards, any cracks in the floor of your bathroom can lead to serious problems. Seeping water could become dangerous quickly, as water manifesting in light fixtures on the floor below could cause short circuits and damage electrical work. Tile is an excellent option for keeping floors waterproof, controlling seeping water from moving through to the floorboards.
Make sure that if you have a tile floor already installed in your bathroom, that you are sealing grout annually. Further, honed tile is a slip-resistant surface, and as a result, will keep both washroom surfaces, family and friends safe.
The section behind your shower is a serious breeding ground for moisture build-up and as a result, mould growth. Waterproof boarding or wallboard installed between the finished wall and insulation will prevent leaks from happening, and mould and mildew from forming. Make sure to seal your walls following the insulation process.
Not only will installing a moisture barrier preserve the surfaces of your bathroom, it will help to insulate it. Having a properly insulated bathroom will keep warmth in, especially during those chilly months. Another bonus is that this will keep energy bills at bay, and costs down in turn! If you're an environmentally conscious household, it would be worthwhile to install a moisture barrier.

The myth, the legend; yes, waterproof paint exists for your bathroom. When using paint in your bathroom, it is very important that you choose a waterproof coating paint to make sure severe damage does not occur. Not only should waterproof paint be used in your bathroom, but the surfaces should be properly primed with a waterproof primer before slapping on a coat of paint.
Make sure that primer has completely dried before moving on to painting. Waterproof paints are oil-based, this way water will bead off the walls rather than embedding itself into the surface. Painting with waterproof paint will follow the same method as regular paints, so make sure your bathroom is properly ventilated while completing this job.
As stated, the bathroom is a very humid place and the more air that can escape, the more waterproof the space will be. When humidity collects on bathroom surfaces, tiny black specks of mould will begin to grow on newly painted walls and ceilings, even if waterproof paint has been used. Mould and mildew growth is a nightmare for any homeowner, as it can lead to various health problems.
Regardless of if you have a window that opens in your bathroom, it is recommended that you install an exhaust fan to further eliminate the build-up of moisture on surfaces.
