A retrofit seal for existing floor waste penetrations. The polymer cap sits over the penetration and seals watertight, blocking sewer gas as soon as it is on: no slab cutting, no pipe replacement, no debris falling into the waste while you work.
Waterproof over it straight away. It suits ceramic and concrete substrates in wet areas from home bathrooms to commercial kitchens and public washrooms.

Substrate guide
Proper surface preparation ensures the Wondercap RetroFit Kit achieves a secure, watertight seal around existing pipe penetrations.
Concrete
Surface prep: Ensure the concrete surface around the pipe is clean, dry, and free from loose debris, dust, or oils. Any rough edges should be smoothed to allow a flush fit.
Primer: Not required for this application.
Ceramic tiles
Surface prep: The tiled surface must be clean, dry, and structurally sound around the penetration. Remove any grout residue or loose tile fragments that might interfere with the seal.
Primer: Not required for this application.
Waterproof membranes
Surface prep: The membrane surface must be clean, dry, and intact around the pipe. Ensure no punctures or damage to the membrane that could compromise the seal.
