Warm, humid temperatures, lack of windows and ventilation and excess moisture build up create the perfect environment for mould or mildew growth. While you may think your shower tiles and composite are enough to resist moisture, they are no replacement for proper waterproofing.
Over time, water seeps between the tiles and into the flooring beneath, putting your bathroom at risk of mould, mildew and foundation or wall rot. So, if you want to protect your bathroom with DIY waterproofing, follow these simple steps!
Plan ahead
Waterproofing needs to be applied to your shower right before you’re ready to place tiles. Make sure you leave yourself enough time to build up coats of Liquid Rubber, keeping in mind that showers require four coats.
Clean all surfaces
Thoroughly clean the entire shower footprint and surrounding walls (sanding if necessary). Remove all dirt and dust from wall and floor surfaces and allow the entire area to dry before continuing.
Bridge the seams
Bridge all the seams, cracks, joints and corners in the shower using Geo Textile. First coat these areas with approximately 1 mm Liquid Rubber and lay your Geo Textile down while the coating is wet. Smooth out any ripples. Allow the Liquid Rubber to dry for about an hour (give it longer if you’re in a humid climate).
Once dry, apply an additional coat of Liquid Rubber to fully seal the Geo Textile. Allow the new coat to dry for 4-6 hours (until dry to the touch and all one colour).
Apply your Liquid Rubber membrane
Apply Liquid Rubber to the entire shower surface with a 10mm microfiber roller. Aim to lay down a heavy coat of Liquid Rubber with a thickness of 1-1.5mm. Wait 4-6 hours for this coat to dry completely. Again, this time frame may be slightly longer if you’re working in a high humidity temperature.
Layer up coats
Make sure your first coat is dry to the touch and then apply a second coat on top and allow to dry to another 4-6+ hours. Continue this method for another 2 coats for a total of 4 coats. Each coat should be uniform in depth and colour, with even coverage.
After your final coat, let the area cure for at least 48-72 hours. Once fully cured, you can apply your tiles directly to the waterproofing membrane using a polymer modified thin set grout.
