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.
