Fermacell Pipe Penetration Patches for sealing around fittings and pipe penetrations
The fermacell Pipe Penetration Patches are made from alkaline-resistant and permanently elastic polypropylene-material for high quality watertight protection. They are part of the extensive fermacell sealing system with general building authority test certificate (P-5079/1926 MPA-BS).
Application
Fermacell Pipe Penetration Patches are designed for permanent watertight sealing in wall areas for pipe penetrations, shower and bath fittings under tiles, boards and ceramic coverings.
Properties
- Extremely elastic and longitudinally stable
- Ageing-resistant
- Maintains a watertight seal
- Secure connections with fermacell Waterproofing Application and fermacell Flexible Tile Adhesive
- High compatibility:
- Compatible with commercial tile adhesives and solvent-free coatings
- Compatible with silicone sealants
- The surface is prepared with fermacell Deep Primer (min. drying time 2 hours) and a single application of fermacell Waterproofing Application.
- The patch is then placed over the pipe opening and pressed in the freshly applied Waterproofing Application, and pressed into place (object must not be sharp-edged) and recoated with fermacell Waterproofing Application.
- After a drying period of at least 1 hour, the second coat of fermacell Waterproofing Application is applied. The application of a 3rd layer is possible, but not necessary. The dry film thickness of the Waterproofing Application is min. 0.5 mm.
- After approx. 2-3 hours, fermacell Flexible Tile Adhesive (or a tile adhesive pursuant to the general building authority test certificate) can be applied to the Waterproofing Application in the thin-bed process.
