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.

Key Features & Benefits

• 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.

Usage & Application

• 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.

Why It’s a Quality Product

• 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.
