When it comes to shower sealer and leaking shower issues in Sydney, one of the most prevalent inquiries is, “How can I seal my leaking shower?”

It’s vital to realise that neither tiles nor grout is completely waterproof. The waterproof membrane below the tiles, on the other hand, is, if installed according to Australian Standards. Any water that gets under the tiles and grout will drain into the overflow flange at the shower base. Is the quality of your shower up to your expected standard? Take a moment to read Megatreat’s helpful guide to make sure your shower is in good working order before you use it again.


Points To Note Before Applying Shower Sealer in Sydney

To make a shower waterproof it must

  • Be grouted appropriately
  • Have a water-proof membrane that is properly installed.
  • Silicone should be positioned behind the tapware and fittings.
  • Have a puddle flange that is properly installed.
  • Seal the shower floor and wall corners with silicone.
  • Have a shower screen that is silicone-sealed properly.

 

Checklist Guide for Leaking Shower in Sydney Before Waterproofing

  • Checking The Shower Grout

Shower sealers and waterproofing might be jeopardised by improperly grouted tiles. Keep the following in mind when evaluating the grout in your shower:

  • Grout that is crumbly, soft or powdered (an indication of poor mixing and application)
  • If there are any noticeable holes in the grout
  • Grout that is cracking or deteriorating
  • If there are any cracks in the grout, it’s time to replace it (especially along with the corners of your shower)

  • Inspection of The Shower Corners

Movement joints should be considered anywhere the tiles change plane, such as inside corners or where the wall meets the floor. It is highly advised that these joints be sealed with a flexible material that can accommodate movement, such as silicone.

Grout has very little flex and, as a result of small structural movement, might crack along these seams, jeopardising shower sealers and waterproofing in Sydney. Check that these joints are properly sealed with silicone to guarantee that your shower is sealed.

Look for the following things when evaluating your shower:

  • There is a lacking of silicone in the shower corners.
  • Silicone in your shower is peeling or decaying.

It’s important to note that mouldy silicone isn’t always a sign of a leaking shower problem in Sydney. Water should not get behind the back of the silicone if it has been done properly. Mould on the surface can be removed. But if mould forms underneath the silicone bead due to water getting behind it (due to poor construction or decaying silicone), it will need to be replaced.

  • Check The Shower Fixing and Tapware

Where the tiles or waterproofing membrane are exposed, a properly applied shower sealer from a reputable shower seal manufacturer in Sydney should have silicone sealing behind the tapware and other fixtures (e.g. screw holes for soap dishes or shower racks). Water can get under non-sealed tapware and behind the tiles if they aren’t sealed, causing water damage. Remove the tap handle and fluid apron to reveal the tap stud underneath and inspect your tapware.

  • Inspecting The Shower Screen

The joint between the shower screen and the tile surface or floor, like the shower corners, should be regarded as a movement joint because they are two substrate types with different movement possibilities. A properly sealed shower screen functions as a barrier, preventing the water from a leaking shower to affect the other parts of the bathroom. Applying silicone on the interior, in our experience, is less likely to cause future shower sealer issues in Sydney.

  • Check the Shower Drain

A solid drainage system is one of the most important aspects of shower waterproofing. This should include installing a puddle flange correctly. Any water that gets through the tiles and grout is supposed to strike the waterproof membrane and drain into the drain through the puddle flange.

Remove the metal drain cover first to inspect your drain. Remove the tiled grate from your shower and look for the drain hole. Next, feel for a slotted gap between the lip of the drain top and the PVC pipe below by tracing your finger around just below the mouth of the drain. Knowing exactly what you’re looking for can take some practice. If you have any questions, please contact Megatreat to speak with one of our professionals.
