  • RED GARD MEMBRANE
  • SHOWER PAN LINER SHOWER DRAIN INSTALL
  • AQUA DEFENCE MEMBRANE

Measure, Mark, & Mix

Install your Wondercap outer flange base to the base of the shower using shallow screws.

Once installed, measure you pre-slope to a grade of ¼” per foot.

Proceed to prepare your mortar mix with course river sand and cement mixed 4-parts sand to 1-part cement.

Create Preslope

Install the prepared pre-slope with a grade of ¼” per foot.

Mark the surrounding walls with black permanent marker that will act as bench mark to work to. Make sure the packing mixture is stamped down hard with a steel float to the level required at the drain and to the outer walls.

Using a spirit level, check all sides for level and double check the grade slope from the outer walls that there is grade towards the drain.

Apply First Layer

Use sand paper to roughen the PVC flange prior to applying your first layer of RedGard.

Apply RedGard to the edges and over any holes from screws to seal off.

Paint over edges & apply the banding

Coat the entire base with Red Gard.

Cut and lay your banding strips to the drain.

Seal Drain & Coat Entire Base

Apply another layer of RedGard to the banding strip to ensure the seal.

Seal Corners with Banding Strip

Apply a layer of RedGard to the walls, following with banding strip.

In the corners; create pig ears to lock in a seal. Following with another layer of RedGard.

Triple Seal Shower Drain

Apply primer to the inner part of the installed flange, and to the outer edge of the inner flange. Followed with PVC glue to both flanges. Apply a small bead of silicone to the upper edges of the inner flange.

Insert the inner flange to the outer flange using a twisting motion.

Apply Final Layer

Use a roller to apply your final layer of paint to ensure a firm seal in the shower base and shower drain.

Proceed to Tile

Allow to dry for 24 hours (RedGard dries red). If necessary, apply another coat or as per manufactures instructions.

 

Once dry, proceed to bed and tile your shower base using the cap as a guide for cutting round tiles if using a round grate.

Shower renovation preparation

Before demolishing your bathroom or shower you should remove the previous drain and insert the Wondercap 3" base into the drain in order to prevent debris entering the drain pipework.

Once you have cleared the floor and the shower flooring installed, remove the Wondercap base and install the whole shower drain kit into the drain outlet. Apply mortar to the flooring for the pre-slope.

The Shower Pan Liner & the Wondercap Shower Drain

Remove the inner flange and base component and lay the shower pan liner over the shower base as per manufacturers instructions. Locate the hole of the outer flange and cut a hole in the pan liner with a knife.

Use a silicone sealant to glue the liner to the outer flange underneath the liner and add a ring of silicone sealant to the top of the liner.

Apply solvent glue to the outside of the inner flange and the inside of the outer flange. Insert the inner flange into the shower drain and use a twisting motion to seal tight.

Applying MORTAR MIX

Raise the Wondercap base to the required tile height and pack in mortar mix to hold. Add mortar mix to the flooring and create the final slope to allow the water to drain. The base & cap component are able to be adjusted into the exact position needed to create a flat shower drain strainer finish.

Tiling

Use the cap as a guide to cutting tiles to fit the round shower drain perfectly.

 

In cases where each height is needed, cut the tail end of the cap off and insert into the base to give the grate added height.

FINISHING TOUCHES

Finish with removing the cap and installing the Wondercap shower drain grate.

Measure, Mark, & Mix

Install your Wondercap outer flange base to the base of the shower using shallow screws.

INSTALLATION STEP BY STEP

RedGard - Painted waterproof Membrane

The installation instructions are guild only for the connection to the Wondercap Shower Drain always read prior to installation the manufacturers recommendation & requirements

Installation of the Wondercap Shower Drain to the prep -slope and the RedGard Waterproof membrane

Installation instructions & shower applications can be found in The Wondercap website www.wondercap.com under “Using Shower Pan Liners”

You have chosen to use RedGard waterproofing membrane for your next shower install and you are looking for more; a better connection, an easier installation, no more bedding & tiling grout into the drain and a more premium finish to your shower drain. Look no further the Wondercap is here.


The following steps will explain how to connect, install and how to install our product to the RedGard

Preparation and planning for the shower drain

  1. Note: The RedGard application requires a pre-slope and so the drain location does not impact on the shower installation it is always a good building practise to center the drain in the shower so that the water drains evenly
  2. The Wondercap is a standard shower drain with improved technology to make your next installation easier
  3. The hob / rough threshold is to be determined prior to installation the pre-slope

a) There are several types of hobs to consider

4. Timber studs cut to size and joined together to meet the measurement required – pvc pan liner

  a) Timber studs and pan liner to be encased in sand cement.

  b)Hob to the height and thickness as required.

5. Timber studs cut to size and joined together to meet the hob to the height and thickness required and sheeted over with Durock cement wall.

6. Hob can be formed with the pre-slope to the height and thickness required.

7. The Wondercap will connect to the drain in the same way as other shower drains via a 2” socketed outlet that can be connected to either the existing drain pipe or a new installation.

8. The Wondercap lower flange can be easily screwed down to the location of your choice and has a larger surface area to firmly attach the lower flange to the timber floor.

9. The lower flange has a ½” thick lower flange that will allow extra thickness of the pre-slope to support & grade to the drain.

10. This shower will require Durock cement wall sheeting to be installed to the shower walls and hob prior to the pre-slope installation.


Installation of pre-slope

  1. Remove the base & cap from the upper flange and set aside and install the blue test plug into the upper flange. This has 2 actions; one is to stop the pre-slope from entering the drain and the second is to make trowelling the pre-slope towards the drain easier.
  2. The Wondercap has been specially designed for paintable water proofing membranes with its formed grade in its flange guaranteeing the draining of sand & cement, and tilers bedding reducing mildew, sweating and water leaks.
  3. If you so choose, install the expanded metal lath prior to installation of the pre-slope.
  4. The pre-slope consists of course river sand and cement mixed 4-parts sand to 1-part cement.
  5. Mix the sand cement evenly to blend the mixture –using a very wet sponge, squeeze the water from the sponge evenly over the mixture and turn it over until mixed, repeat this process until mixture changes to a darker color. A good mixed pre-slope mix holds together in your hand; too wet and it will take extra time to dry and be difficult to work with. A pre-slope installation should take no longer than 30 minutes to apply, pack and grade to the drain.
  6. a) Install the prepared pre-slope with a grade of ¼” per foot

b) mark the surrounding walls with black permeant marker that will act as bench mark to work to

c) make sure the packing mixture is stamped down hard with a steel float to the level required at the drain and to the outer walls

d) establish the levels around the drain and then the outer walls. Roughly apply the mixture between the established levels and using a 24” piece of timber as a straightedge/screeding bar, screed between the established levels and level out.

e) using a spirit level, check all sides for level and double check the grade slope from the outer walls that there is grade towards the drain – you have to get this right so spend the time making sure this is correct.


RedGard Membrane to the shower drain connection

  1. Allow the pre-slope dry overnight – leave the test plug in position
  2. Prep the dried pre-slope by removing and sponging the pre-slope and surrounding walls.

Note the base and walls have to be dry and clean prior to using the RedGard

3. Pre-cut 4 x 14” bonding strips for the drain, 7 x the length of each wall & hob bonding strips, 4 x 36” bonding stirps for the corners and 4 x 4” bonding strips for the corners of the hob.

4. Apply a thin coat across the lower flange forming a 14” square around the lower flange – install the pre-cut 14” bonding strips on the wet membrane and then apply a liberal first coat of RedGard across the bonding strips.

5. Continue to apply the RedGard evenly across the shower floor, up the walls, into the corners where the bonding strips are being installed. Apply the pre-cut 36” bonding pieces into each corner and apply a coat over the bonding strip.

6. Continue to apply the RedGard over the hob, ensuring the corners and bonding strips are evenly coated.

Remember: RedGard starts pink and dries completely red. Be sure to check the membrane is dry.

7. Remove test plug and apply a bead of silicone evenly around ½” from the outer edge of the lower flange.

8. Prep & clean the outer tail of the upper flange and the inside of the lower flange with primer and then glue around the inlet and outlet evenly. Insert the upper flange into the lower flange and press down with twisting action to glue the drain together and to silicone seal evenly.

You have now sealed the RedGard membrane to the double flanged Wondercap with a glued connection; a feature of the Wondercap’s triple seal connection

9. Apply a 2nd coat of RedGard membrane, taking care in the corners and around the drain ensuring everything is evenly coated.


Flood testing the shower installation has never been easier

  1. Allow the RedGard membrane to dry overnight before flood testing the shower to make sure that connection is watertight - ideally let it test for 24 hours. Remember: RedGard starts pink and dries completely red. Be sure to check the membrane is dry.
  2. After the testing has been successful remove the test plug and insert the Wondercap base & cap
  3. Apply the bedding to the thickness required – raise the Wondercap base and cap to the height required.
  4. Pack bedding under the head of the base into position and level with a spirit level. Continue to bedding to the top of the cap and to the outer walls as required

Pro-tip: mark the surrounding walls with a marker allowing the correct grade required that will act as bench mark to work to.

5. Allow bedding to dry before tiling


Tiling

1. Glue and lay tiles on the applied bedding as required and to the round cap. Complete tiling within one tile from the cap

2. Remove the cap and use as a template (the width of the cap is same width as the round grate) for marking and cutting out around the tile to suit the round grate

3. Complete tiling as required.

Pro-tip: if the grate sits below the finished tile height required, simply measure from the finish tile level to the top of base (cap has been removed). Raise and support the grate to the required level by measuring and cutting the lower part of the cap to the required the length (example ½”) and then insert into the base. It will support the grate to the required height; support with glue if required.

4. Repeat the process for the square grate except mark the tiles in position prior to cutting

Shower Pan Liner Shower Drain

  1. Position the Wondercap Tiled Shower Outlet into shower drain outlet – ideally, the location should be in the center of the shower.
  2. Clean, prime and solvent-weld flange tail 1 into drainage pipe. Ensure flange sits flush with Floor and secure with 4 counter-sunk screws.
  3. To form the pre-slope, mark out the height of pre-slope on external walls of shower, allowing a fall of ¼” per foot. Fill with dry pack mortar and screed back to edge of outer Wondercap flange 1 . Install the curb/rough threshold. Once bedding is set, form the curb/shower step by packing in a dry mortar mix and troweling to the desired thickness of shower step. The curb should be no less than 2” in height above the internal shower bedding floor and no more than 9” in height.
  4. Once dry, remove inner flange 2 and the base 3 & cap 4 component and set aside.
  5. Position shower pan liner 8 over the outer flange 1 and install pan liner as required by manufacturer. The sides of the pan liner are supported and nailed 1” above to the pre-installed horizontal timber support.

PRO TIP! It is important the liner is turned up the walls at least 3” higher than the finished dam and the pan liner sides are nailed no lower than 1” above the finished curb (shower step) or threshold. The liner should extend up and over the curb(where shower door/ screen will sit) and fasten to the outer floor area. Prefabricated corners can be bonded in areas where folding is not possible.

  1. Locate inner edge of outer flange 1 (screwed to the floor) and carefully cut away the inner circle of the pan liner.
  2. Apply a ½” bead of clear, all-purpose silicone (caulking) sealant to inner top surface of the outer flange 1 (on the surface of the shower pan liner) and ½” bead of silicone to the underside of the inner flange 2 (½” from edge).
  3. Clean, prime and solvent-weld inner flange 2 and outer flange. Insert flange 2 through the pan liner and press down with a twisting motion, maintain a firm pressure for a few seconds until the solvent cement has taken hold.

PRO TIP! Using the supplied blue test plug 5 , flood test the shower pan liner. The shower pan liner flood test should be held for up to 4 hours to guarantee a water tight connection. Discard test plug 5 after use.

  1. Reinsert the Wondercap base 3 & cap 4 component into the inner flange 2 . Raise the base 3 & cap 4 component to required mortar height and apply a mortar mix in and around the underside of base 3 & cap 4 to support and hold in position – always use a spirit level to ensure the base 3 & cap 4 component is perpendicular to the flange 1 . Do not remove protective cap.
  2. Screed the shower bed with 1” layer of prepared mortar mix and lay a suitable galvanized steel mesh or metal lath over the shower prepared mortar and continue the metal lath across the shower rough threshold (the step).
  1. Apply the remaining mortar mix over the mesh or lath. Screed back to shower drain outlet while maintaining correct grade as per standard building requirements.
  2. When laying floor tiles, the fall is maintained towards drain and tiles are cut around the round strainer using the protective cap 4 or strainer 7 as a template. Square strainers are set up and cut around as required.
  3. Finally, remove protective cap 4 and seal in the desired strainer 7 with tile glue and grout.

PRO TIP! Raise adjustable base to required mortar height, allowing for tile thickness.

PRO TIP! For connection with 2” linear drains insert Wondercap reducing bush 6 into base 3 . Discard if not required.

PRO TIP! If you have not allowed for tile thickness, continue tiling to the drain outlet. Tiles will finish ½” above the top of the base 3 & cap 4 . Remove cap and cut internal edge of cap 4 to the height required to support selected strainer (as per detail) to finish flush with the tiles.

Remember: Discard test plug 5 after use and if NOT installing a linear drain connection, discard reducing bush 6.
