Description

High-Performance Ready-Mixed Salt-Resistant Renovating Plaster for Damp Walls

Biokil Crown Premium M+ is a ready-to-use, lightweight renovating plaster formulated to provide a breathable, salt-resistant render for use on damp or salt-contaminated internal walls. Specially developed for use after the installation of a new damp-proof course (DPC), it prevents residual ground salts from migrating into subsequent decorative finishes. Ideal for renovation, refurbishment, and conservation work, Premium M+ delivers a long-lasting, smooth finish without requiring gauging or blending.

  • Smooth & Lightweight: Easy to apply and finish with standard tools — provides a durable base for final coatings.
  • Multi-Layer Use: Suitable for use in both base and finishing coats over treated or contaminated backgrounds.
