SUPERFLEX COLLAR Penetration collar
Pre-formed elastic TPE waterproofing collar for pipe and tap penetrations
Pre-formed felt-faced collar that grips pipes from 10 mm to 40 mm and locks into the membrane.
SUPERFLEX COLLAR coverage, coats and cure times
Pre-formed TPE collar with felt on both faces for taps, shower outlets and pipe penetrations. It is pressed into wet liquid membrane and covered by a second coat.

- Commercial wet areas and plant rooms
- Any liquid membrane system needing a pre-formed penetration detail
Know before you start
- Not a membrane: embed it in a liquid membrane system
- Wet membrane only: never tacky, skinned or cured
- Not for unprotected UV exposure or negative pressure waterproofing

How to apply SUPERFLEX COLLAR
- 01
Prepare
Clean, dry, sound substrate. The pipe must be rigid, firmly fixed and deburred. Fill gaps and oversized penetrations with ACTFLEX 75FC or ACTFLEX MS PRO and let it cure. Prime if the membrane system needs it.
- 02
Base coat
Apply a generous wet coat of compatible membrane around the penetration, at least 150 mm out from the pipe, and keep it wet.
- 03
Position
Stretch the collar over the pipe so the centre grips it and the collar sits flat with no lifting edges.
- 04
Embed
Press the collar into the wet membrane from the centre out. Brush, roll or trowel out air pockets and creases so the felt is fully saturated.
- 05
Check
The membrane must bleed through the felt. Confirm no dry spots, no trapped air, no lifting edges and full contact to the substrate.
- 06
Cover
Apply the second coat to encapsulate the collar, wet-on-wet (preferred) or once the base coat has tacked off. Cure, flood test, then tile or cover per the membrane TDS.

SUPERFLEX COLLAR questions
What pipe sizes does it fit?
The central hole is 10 mm and stretches to 40 mm. Do not stretch it past 40 mm, because the elastic core then loses its recovery.
How many collars do I need?
One per penetration. Count every tap, shower outlet, floor waste, spout and service protrusion as a separate collar.
Why must the membrane be wet?
The felt has to be saturated for the collar to bond. A collar pressed into tacky, skinned or cured membrane will not bond. Membrane bleed-through is your visual check.
How much membrane does each collar take?
A 300–350 mm zone around the pipe, roughly 0.07–0.10 m² per coat, in two coats. That is on top of the field coverage.
What if the gap round the pipe is big?
Fill gaps and oversized penetrations with ACTFLEX 75FC or ACTFLEX MS PRO first. The collar seals a penetration, it does not bridge a void.
Can it go in the sun?
Not unprotected. It is not UV stable in storage or in service, so keep collars packaged until needed and cover them with the membrane.
