Promac Easycoat Plaster Primer (WB) is a water-based penetrating primer designed to prepare and stabilise plaster and masonry surfaces before painting. It works by soaking into porous substrates, creating a uniform base that ensures optimum adhesion of topcoats.
 
Formulated for both interior and exterior use, this primer provides resistance to alkali and moisture, helping to protect paint systems from common issues such as peeling, flaking, and efflorescence.
 
Its breathable formulation allows trapped moisture to escape from the surface while still sealing it, making it ideal for walls that require a balance between protection and permeability.
 
With quick drying times, low odour, and easy water clean-up, Easycoat Plaster Primer WB is a practical and user-friendly solution for both DIY and professional projects.
