Knauf Perlfix — Adhesive for fixing plasterboard and panels
Joint treatment materialsDescription
A gypsum-based adhesive plaster that fixes plasterboard and composite panels directly to the wall, without a metal framework. The quick ‘dot-and-dab’ dry construction method for interiors.
Knauf Perlfix is a gypsum-based adhesive for fixing plasterboard and composite panels (thermal/acoustic insulation) to solid internal walls. It is applied in dots (dot-and-dab) to the back of the board or to the wall; the board is pressed into place and levelled, smoothing out minor irregularities in the substrate.
Adhesive application or framework?
- Perlfix (adhesive application/dot-and-dab) → quick, no framework required, for relatively flat solid walls; minimal loss of space.
- Metal framework (CW/UW) → for uneven walls, electrical and mechanical installations, cavity insulation, great heights, acoustic decoupling.
- Substrate preparation: absorbent wall → Tiefengrund primer; smooth concrete → Betokontakt, prior to bonding.
Overview
Key Features
- Frameless bonding — rapid dry construction.
- For plasterboard and composite panels (thermal/acoustic insulation).
- Levels out minor wall irregularities.
- For internal use; gypsum-based.
