Balcony Waterproofing | 3 DIY Actions To Waterproof Your Balcony Edges And Floors

If you are redoing your balcony tiles, then you probably want to undertake waterproofing before tiling to ensure that rainwater doesn't leak from the areas where the floor touches the walls and on the floor surface itself to protect from potential leaks developing over time. While this commentary helps you with DIY actions for leak prevention, you may want to consider hiring professional waterproofing contractors if you need major waterproofing repairs for your balcony.

Bring Your Waterproofing Materials Together

For this waterproofing balcony task, you will need acrylic waterproofing primer and waterproofing membrane. This can be applied with a paintbrush on your balcony floor edges and floors. The primer and membrane will prevent moisture and water from seeping through the concrete sub-floor and will improve its strength once cured. You can get both primer and membrane from a home improvement or hardware store. Since they are available in different quantities, you can choose based on the size of your balcony. Choose fast-drying products to reduce your work time. These products may also be used for roof waterproofing and concrete deck waterproofing.

Apply The Primer And Membrane To The Edges And Floors

Before your balcony is tiled, apply the primer to the floor and edges of your balcony using a paintbrush. Be generous with your application because you want the primer to evenly coat the floors and edges. Wait for the product to cure based on provided instructions. Once the primer has dried, apply the waterproofing membrane in the same way. Pay close attention to joints and corners and make sure you cover them properly with primer and membrane. Water-based products are always best because they are non-toxic and don't leave any noxious odours.

Wait For The Waterproofing Membrane To Dry And Do A Water Leak Test

The manufacturer will offer recommended drying times, so make sure you follow this judiciously to prevent issues once the tiles have been installed in your balcony. Once you're satisfied that the membrane is dry, do a water leak test by wetting the balcony. Let the water sit on the balcony and check under it for any signs of water leaks. If everything is normal, you may proceed with the tiling task. If water leaks, then it's possible that there is a hairline crack somewhere. Waterproofing contractors with professional tools and experience are best equipped to pinpoint and fix these leak problems before they get worse in your home.

While these actions will help you with your balcony waterproofing task, it's probably always best to hire a professional to ensure that there are no expensive leaks to contend with later. If you are based in Sydney, you can expect waterproofing to start from $35 per square metre.
