## Passive Fire Protection Specialists Serving the Entire South IslandIntumescent Coating Solutions South Island
Straight Cut Intumescent Ltd makes intumescent application easy for builders, architects, project managers and homeowners throughout Christchurch, Canterbury and the wider South Island. As an owner-operated specialist in intumescent coatings, the business delivers precise, high-performance fire protection coatings for structural steel and architectural timber in both commercial and residential buildings. Every project is personally managed and sprayed by the owner, so clients get the consistent, considered finish that large commercial crews often struggle to match. Intumescent coatings expand when exposed to heat, slowing the spread of fire, buying occupants valuable evacuation time and helping to preserve a building's structural integrity — protection that quietly does its job for the life of the building.
Intumescent Paint Applicators South Island
Whether a project calls for intumescent paint for steel or intumescent coating for timber, Straight Cut Intumescent works to the exact requirements set out in the fire report. Timber coating systems are applied to achieve New Zealand's Group 1-S fire rating for interior timber, while fire-resistant paint for steel is applied to meet the specified Fire Resistance Rating on interior and exterior structural steel. As an approved applicator for industry-leading Zone, Altex and FireShield coatings, the business remains completely product neutral — recommending the most compliant and cost-effective fire safety coatings for each individual job rather than pushing a single brand. Clients can also expect specialised application techniques that protect timber aesthetics, ensuring clear coats never go milky, cloudy or white over time.
