Project Spotlight: Intumescent Fire Protective Coating in Twickenham

Behind every modern commercial development or major refurbishment, safety is the number one priority. One of the most critical elements of building safety is ensuring that structural steel is adequately protected against fire. At Pro Coat Solutions LTD, we specialize in the rapid, precise application of intumescent coatings.

We recently completed a fantastic project in Twickenham: a 4-story building featuring a ground-floor shop that is being fully converted into luxury flats. For a mixed-use conversion of this scale, spraying fire-protective paint on the exposed steel beams was a critical path requirement to pass modern building safety regulations.

What is Intumescent Coating?

Intumescent paints are highly engineered coatings designed to expand significantly when exposed to extreme heat. This expansion creates a thick, insulating layer of "char" around the steel. This char dramatically slows down the rate at which the steel absorbs heat during a fire, preventing the steel from losing its structural integrity and collapsing.

This critical delay (often rated for 30, 60, 90, or 120 minutes) allows valuable time for safe evacuation and for emergency services to respond.

The Challenge of Steel Works

Structural steel presents unique challenges. Beams are often located in hard-to-reach areas, high within ceiling voids, or part of complex architectural geometries. Furthermore, the application must be extremely precise: building control and fire safety regulations dictate exact "dry film thicknesses" (DFT) that must be achieved and verified to guarantee the specified fire rating.

Our Machine-Sprayed Solution

Traditional brush or roller application for intumescent paint is painstakingly slow and often results in an uneven finish that can fail thickness tests.

By utilizing our advanced airless spray systems, we can achieve:

• Unmatched Speed: Covering vast expanses of steel in a fraction of the time, keeping demanding conversion schedules—like this 4-story Twickenham build—on track.
• Precision and Compliance: Ensuring an even, consistent film thickness across all flanges and webs of the steel beams—making full compliance guaranteed.
• Superior Finish: Even for a functional coating, aesthetics matter in modern "exposed services" designs. Our spray application delivers a clean, uniform texture.

The final textured finish securely protecting the structure.
