Waterproofing Detail for the Wondercap Kit - WC100K 100mm
*Note - For sizes 80mm and 50mm the same installation information applies.
Installation Instructions:
Tips & Tricks:
- Always review the waterproofing manufacturer's requirements before starting the installation. 
- Product Material: Our puddle flanges are made from durable ABS plastic. 
- Primer: A non-porous primer is required to prime and clean the surface area as necessary. 
- Test Plugs: Lightweight test plugs are available for easy installation when you order from your local supplier. 
- Install the first layer of waterproofing and bonding strips across the puddle flange before applying the tile bedding. Ensure the waterproofing membrane is completely dry before continuing. 
- Before starting, review the instructional videos by scanning the QR code for professional guidance on waterproofing membrane installation. 
Required Information:
- Review the manufacturer's guidelines for water testing the shower membrane area, especially regarding curing times for the membrane product you're using. 
Installation Steps:
- Set up the Base & Cap: Position the base and cap to the required level for the bedding datum. This will serve as the reference level for the drain when spreading the bedding material. 
- NCC Requirements: The NCC mandates a 1:80 grade for shower bedding towards the drain—this is a mandatory requirement. 
- Bedding Thickness: The recommended bedding thickness is a minimum of 25mm above the puddle flange. 
- Bedding Transition: The bedding should finish just before the puddle flange, tapering back at a 45° angle to allow for a smooth transition to the edge of the puddle flange. - Tip: A 45° angle provides the best smooth transition from the bedding to the puddle flange, especially when using bonding strips and waterproofing. 
 
- Waterproofing Coats: - Apply the first coat of waterproofing and allow it to dry completely before applying the second coat. 
- Apply the second coat of waterproofing and allow it to dry thoroughly. 
 
Important Notes:
- The NCC highly recommends water testing of the waterproofing membrane, but it is not mandatory. 
Benefits:
- The test plug is easily inserted into the mouth of the puddle flange and can be used for water testing to ensure the waterproofing membrane is sealed and watertight. 
- When conducting a water test, remember to record and date the results for your records. 
- Review water testing procedures by scanning the QR code for additional video guidance. 
Final Installation Steps:
- Insert the Base & Cap: Raise the base and cap to the required finishing bedding height or grate height. 
- The base and cap should be held in place with a damp bedding mix under the edge of the grate adapter, base, and cap. 
- Fill the Gap: Install the bedding mix to fill the gap between the grate, base, and cap, ensuring the bedding is level with the finished height.
