A STEP BY STEP GUIDE ON HOW TO WATERPROOFING YOUR BATHROOM

When waterproofing a shower it's important to know exactly where you are putting your shower and knowing where the water could possibly reach once you have chosen the design and frame of your shower, as well as the shower head. Once you know exactly where it is going and where the water could possibly spray, it's time to start measuring and waterproofing your shower. Prior to any waterproofing, make sure you have installed your Wondercap Retro Kit. The retro kit shower drain is designed to allow you to waterproof and bed your shower all whilst keeping a clean drain and even surface.

  • Dustpan and Broom or vacuum cleaner
  • Sand paper
  • Waterproofing rubber paint
  • Grout mix
  • Bedding Mix
  • Paint Brush
  • Paint Roller
  • Primer
  • Tiles
  • Silicone and Silicone Gun
  • Paint scraper
  • Paint mixer
  • Spirit level
  1. Install the WondercapPuddle Flange.  

Use a solvent to glue the Puddle flange tail into the drainage pipe. Then glue the puddle flange brim to the concrete surface. Or you can screw the flange into the concrete, using green plus and counter-sunk screws.  

 

  1. Sweep and Prep

Sweep and prep the surface area of the shower. This will allow optimal results of the waterproofing membrane.  

 

  1. Measure and mark with paper tape.

Grab yourself a pencil and a measuring tape, it's important to get this perfect for the best result. Measure up point to point where you are going to have your frame of the shower, and give yourself an extra 100 to 200mm for incidents. For a guide its best to extend your waterproofing 100mm above your water outlet and 100mm wider than the edges of your shower. Always check your local council regulations to make sure you're in the clear, and that you won't be having to do another renovation anytime soon. Once you have pin pointed your measurements, it's time to get the good old masking tape out and start masking out your waterproofing area.  

TIP* Mark the floor into 4 parts so that once priming you can allocate what is drying.

 

  1. Prep the area

Now it's time to pop on those gloves and get out a brush! It's time to prime that area! If you have any left over paint or uneven surfaces, make sure you sand it back to give yourself the best surface possible. The primer needs to be a paint that is appropriate for waterproofing. Best to ask your local hardware store which one they will advise on as most of the time they have products that work well together. Otherwise see out list below for "what you need to waterproof". Now that you have your primer, brush or roller, it's time to dunk that brush and start coating! Make sure to use a generous amount, and plan your way through the priming. That way you can start waterproofing whilst the other side of the primer is drying.

TIP* If you marked out the floor, then you can prime 2 squares which are diagonal across. That way you can prime the walls opposite so that once you have finished with the walls you can then finish the floor with the other 2 squares left.

 

  1. Silicone the gaps

To prevent any leaks and spaces, grab yourself a silicone seal gun and fill in the gaps. Hold the silicone gun at a 45 degree angle and squeeze whilst moving in a slow paced. Ensuring that the silicone is distributed evenly for a perfectly sealed corners and edges. After each strip that your have sealed, its best to take a damp finger and just stroke your finger down the silicone to make sure its concealed tightly into those gaps. Allow 24 hours for drying.

 

  1. Position the Wondercap

Pull out the inner part of the puddle flange and set aside.  

 

  1. Waterproof the Shower walls

Now you can start waterproofing! For perfect adhesive make sure your primer is well dried and that you follow the same process and order to which you painted your primer.  

Use a roller and paint brush to coat the walls and floors.  

 

  1. Waterproof the Wondercap

On the shower drain retro kit puddle flange you will see a clear line written "water proof to this line", paint all the way up to that line. DO NOT APPLY THE WATERPROOFING PAINT PAST THE LINE.  

 

  1. Second Coat

Give the first layer 24 hours to dry. Then go back in with your waterproofing paint start your second coat of waterproofing membrane to your shower and bathroom floors.

 

  1. Reinsert your Retro shower drain

Reinsert the base (inner puddle flange kit) to the height and position once the waterproofing has dried.  

 

  1. Bedding

Mix your bedding mixture and pop it around the base where needed.

 

  1. Pre-slope Using Bedding

In your four corners of your shower you must have a 1.25cm height above your shower drain bedding for every 30cm out to the edge. For example: if you have a 900mm x 900mm shower floor, you would raise the bedding 1.25cm for every 30cm. Once you have reached 30cm you would then increase it (1.25cm x 2) by 2.5cm, then repeat that to the next 30cm until you reach the 4 corners. This will give you a perfect slope for your shower.

 

  1. Grout and Tile

Now apply your tiles to the wet bedding and grout the tiles.  

 

  1. Cut the tiles to the Wondercap, and use the cap to cut your tiles perfectly!

 

  1. Finishing touches

Now that the grout is dry and the tiles are situated, do a quick mop over the tiles and tiled walls. Take out the cap and place your grate inside. You will now have a perfect waterproofed and tiled surface area with the perfect grate.
