Jotashield Primer is a premium water-based acrylic primer formulated for exterior surfaces, designed to provide a robust foundation for the Jotashield series of topcoats.
Alkali and Moisture Resistance: Seals off the substrate to protect against alkaline and moisture attacks, which helps preserve the structure of exterior walls.
Superb Adhesion: Enhances the bond between the substrate (walls) and the subsequent topcoat, improving durability and reducing risk of peeling or flaking.
Water-Based & Environmentally Friendly: The water-borne formulation offers a better environmental profile compared to traditional solvent-based primers.
Ideal Undercoat for Topcoats: Prepares a uniform, sound surface that enables the final paint to perform to its full potential — better coverage, better finish, longer life.
Suitable Substrate Range: Designed for exterior applications such as cement plaster, masonry, rendered surfaces, concrete blocks and similar exterior walls.
Best used as the first coat (undercoat) on new or bare exterior walls: clean, dry, structurally sound substrates.
Ensure that the surface is free from dust, debris, loose paint, and efflorescence, to achieve optimal adhesion and performance.
Typically followed by compatible topcoats from the Jotashield system for full exterior protection.
Suitable for use in residential, commercial, industrial, educational and hospitality buildings where exterior paint performance and longevity are important.
Provides a strong foundational layer which is often overlooked in painting projects — good primer means the topcoat can shine and last.
Offers technical benefits (alkali resistance, superb adhesion, moisture protection) rather than just aesthetic ones.
Being part of a proven paint system (Jotashield series) means the primer contributes to the overall system’s performance and guarantees.
Water-based formula helps with environmental concerns and lessens harsh chemical exposure compared to many older primers.
