Answering Your Questions About Waterproofing a Bathroom

by Frank Lynch

Every home should be constructed with a vapour barrier or some sort in order to block excess humidity and moisture from being absorbed by the home's framework, causing water damage and mould. The bathrooms of the home may need even more waterproofing to prevent steam from the shower from settling on the walls and floors and causing even more damage to the tiles and other building materials. If you've been told that your bathroom needs new waterproofing, or if you are renovating the bathroom and want to ensure you protect the building materials properly, note a few questions you might have about waterproofing this room, and then discuss your options with a contractor at a company like Westside Sealants Pty Ltd as needed.

How do you waterproof a bathroom that's already constructed?

Various paints that have waterproofing properties can be used on the walls of the bathroom to keep the drywall from absorbing humidity. Coatings are also available for shower tiles to keep them from absorbing water and humidity, and these tiles should also be sealed and recoated on a regular basis. Reglazing the tub can also prevent leaks around its edges.

It's also good to consider coatings for the floor of the bathroom, as the grout and other adhesives that keep tiles in place and that block moisture from settling onto the floor can break down over the years. Be sure you choose coatings meant for each of these materials and surfaces in particular so they are protected properly.

Does blown foam insulation waterproof a bathroom?

Blown foam insulation can work as a vapour barrier, but it may not be sufficient for waterproofing a bathroom, as this room may need added protection from steam, as mentioned. However, this will depend on your local building codes; sheeting may need to be put over the insulation, and it may also need to be a certain height in the bathroom in order to comply with those codes. Rather than assuming that an insulating product is the same as waterproofing, consult with a contractor who specializes in bathroom renovations, and he or she will be able to tell you if your chosen insulation is sufficient.

The bathroom was waterproofed but mould still develops in the tub; now what?

Mould developing in the bathroom doesn't mean that there is an issue with the waterproofing, unless the mould develops behind the walls, which would indicate that the drywall is absorbing that water and allowing mould to form. If mould forms along the tub, you may simply need a stronger bathroom exhaust fan to remove that steam and not allow it to settle in those areas.

Choosing the Right Material For a Construction Project

If you are planning to start a new construction project, you may be wondering about the best type of materials to use. About 6 months ago, I decided to carry out an extensive renovation of my home. This would involve demolishing one wall, extending the kitchen and the construction of a new patio area. I really wasn't sure which materials would be best. I consulted with a contractor and he explained the pros and cons of each material. In the end, I opted for wood and steel. I am really pleased with the end results. I hope this blog helps you to plan your construction project.
