Accreditations

How It Works: From Enquiry to Completion in 3 Simple Steps.

We make it easy to ensure your building is fire-safe and fully compliant, with minimal disruption and maximum professionalism.

Send Drawings or Photos for a Quick Quote

Send us your architectural drawings, steel schedules, or clear photos of the areas that require fire protection. This could include exposed steel beams, columns, or timber structures.

We’ll assess the scope, access requirements, and fire rating specification, then provide a clear, fixed-price quote. No site visit is usually needed for initial estimates.

Site Preparation & Protection

Before any spraying begins, we fully prepare the surfaces and surrounding areas. This includes cleaning, degreasing, sanding loose paint, patch priming if needed, and masking off adjacent finishes or fixtures.

All preparation is carried out in accordance with fire protection manufacturer guidance and safety standards.

Intumescent Spray Application & Certification

Using specialist airless spray equipment, we apply the correct build-up of intumescent coating to meet your required fire rating (typically 30, 60, 90, or 120 minutes).

On completion, we remove all masking, carry out a final inspection, and issue all necessary documentation, including product datasheets, film thickness records, and application certification for building control or fire officer approval.

Choose the Right Finish, Fire Protection Without Compromising on Appearance.

Intumescent paint is typically white and designed for performance, not aesthetics. But if you want your steel or timber to match your project’s colour scheme, we offer a flame-retardant topcoat system that can be tinted to any colour and finish.

This topcoat provides the final visual layer over the intumescent base, with no compromise on fire protection or compliance.

Matt

A flat, low-sheen finish ideal for modern interiors or where a subtle, minimalist aesthetic is required.

Eggshell

A soft, durable finish with a gentle sheen, commonly specified for commercial environments and exposed steel in open-plan office spaces.

Gloss

A bold, reflective finish that adds contrast and is ideal for feature elements or visually exposed structural steel.
