Fietex FX1008 Intumescent Coating

Firetex FX1008 Intumescent Coating Overview

Firetex FX1008 is a single pack, solvent-based thin film intumescent coating designed to provide up to 120 minutes of fire resistance to structural steel. Developed for efficient in-shop application by airless spray, it delivers high film build, certified fire performance, and dependable durability in both internal and controlled external environments.

Firetex FX1008 Solvent Based Intumescent Coating

Firetex FX1008 is engineered to protect structural steelwork against the effects of fire, forming an insulating char layer when exposed to high temperatures. Independently fire tested and approved to major European and national standards, including Certifire (Certificate CF10335), it offers reliable passive fire protection for commercial, industrial, and infrastructure projects.

With a high volume solids formulation, the coating enables substantial dry film thicknesses to be achieved efficiently, helping reduce application time and labour costs. Supplied in white, it can be left un-topcoated in certain dry internal environments or overcoated with approved finishes for enhanced durability and aesthetics.

Applications & Uses

Firetex FX1008 is specifically designed for in-shop application by airless spray to structural steel, providing fire resistance for up to 120 minutes. It is suitable for beams, columns, and complex steel sections in a wide range of building types including commercial developments, warehouses, transport hubs, and industrial facilities.

After appropriate drying, the coating can resist normal weather conditions for up to six months without a topcoat, provided that exposure does not result in ponding water from rainfall or condensation. For externally exposed steelwork or severe internal environments, approved polyurethane or acrylic topcoats should be used to provide long-term durability and colour retention. In internal areas where a decorative finish is required, compatible water-based or solvent-based topcoats may be specified.

Preparation

The coating must be applied over suitably prepared and primed substrates. Surfaces should be clean, dry, and free from oil, grease, dirt, dust, mill scale, and corrosion products to ensure proper adhesion and long-term performance.

In certain controlled situations, application may be possible directly onto steel that has been blast cleaned to a high standard with an appropriate surface profile. For in-shop systems, compatible blast primers are recommended to optimise adhesion and corrosion protection beneath the intumescent layer.

Application should ideally take place at temperatures above 5°C, with the substrate temperature at least 3°C above the dew point and always above freezing. Adequate ventilation is essential, particularly in high humidity conditions, to support proper curing and film formation.

Application

Airless spray is the preferred method of application, enabling high-build coats to be achieved efficiently and consistently. Suitable spray equipment with appropriate tip sizes and pressure settings should be used to ensure optimum atomisation and film build.

A typical spray-applied coat can achieve substantial dry film thickness in a single pass, significantly improving productivity in fabrication shop environments. No more than two spray coats should be applied within a 24-hour period. Exceeding recommended thickness per coat or overcoating prematurely may result in surface cracking.

Brush application is suitable for small areas, touch-ups, and repairs. Due to the high solids formulation, a textured finish may occur, and multiple coats may be required to achieve the specified thickness.

Drying & Curing

Drying times will vary depending on film thickness, temperature, humidity, and air movement. Under standard conditions, the coating will become touch dry within a short period, with recoating possible after several hours.

The coating must be protected from moisture during the drying period. Premature exposure to rain, condensation, or high humidity may affect both the integrity and fire-protective properties of the system.

For temporary external exposure without a topcoat, sufficient drying time must be allowed in dry, well-ventilated conditions. Thicker applications or lower temperatures will extend curing times.

Safety Information

As a solvent-based coating, Firetex FX1008 should be handled with appropriate care. Always follow safe working practices, ensure adequate ventilation, and use suitable personal protective equipment during mixing and application.

Store in tightly sealed containers in a cool, dry environment away from sources of ignition. Proper storage will help maintain product quality and performance throughout its shelf life.
