Product Description

Crown Timonox Upgrade Basecoat is a specialised primer designed to enhance fire safety by upgrading the fire performance of existing painted surfaces. Part of Crown Paints' Timonox range, this basecoat is formulated to work in conjunction with Timonox topcoats to provide an effective fire-retardant system. It is particularly useful in environments where improving fire safety standards is a priority, such as public buildings, schools, hospitals, and commercial properties.

The primary function of Crown Timonox Upgrade Basecoat is to create a stable and fire-retardant foundation on previously painted surfaces. When used with Timonox topcoats, it helps to slow the spread of flames and reduce heat transmission during a fire, thus providing additional time for evacuation and firefighting efforts. The basecoat is designed to adhere well to a variety of substrates, including plaster, plasterboard, and previously painted surfaces, ensuring compatibility and effectiveness.

Application of the Crown Timonox Upgrade Basecoat is straightforward, requiring standard painting tools such as brushes, rollers, or spray equipment. Once applied, it dries to form a robust layer that enhances the performance of the subsequent intumescent topcoats. This system not only improves fire safety but also allows for aesthetic flexibility, as the topcoats are available in various finishes to meet design requirements.

Product Features


Fire-Retardant Char Layer Formation: Upon exposure to heat, this water-based, high-build coating produces a thick insulating char that upgrades Class 4 surfaces to Class 0, slowing flame spread and enhancing fire safety.


One-Coat Application with Excellent Adhesion: Designed for easy use - brush, roller, or spray - it adheres well to timber, plasterboard, and previously painted substrates, simplifying preparation even on challenging surfaces.


Fast Drying and System Compatibility: Dries to touch within about 1 hour and can be recoated after 4–6 hours. It’s intended to be overcoated with Crown’s Timonox finishes for a tested, compliant decorative fire-protection system.
