Fire Retardant Fabric and Wood Treatments
Fire-retardant sprays and liquid treatments are essential safety solutions for slowing the spread of flame across absorbent materials and timber surfaces. These products help reduce the risk of ignition and delay combustion, giving critical time for safe evacuation. While often described as fireproof, it’s important to understand they don’t make materials completely non-combustible - rather, they improve fire resistance and reduce flammability. Used correctly, these treatments support broader passive fire protection strategies and work in harmony with fire stopping systems and structural measures in place.
Rawlins Paints offers a wide range of solutions from Zeroflame to Thermoguard. Both are ideal for surfaces where appearance must be preserved. For fabrics such as curtains, rope, upholstery, and decorative textiles, fire retardant sprays are available for use on cotton, silk, wool, polycotton, and more. Many of these treatments are non-toxic and colourless, providing discreet protection without altering the look of the material. Clear sprays are increasingly used in public buildings, hospitals, schools, and theatres due to strict regulations and high occupancy risk.
Products from Bollom offer tailored protection for artificial plants and decorative fabrics. Application must be done in warm, well-ventilated conditions, and product performance varies by substrate. When combined with fire retardant paints for ceilings and walls, these treatments contribute to comprehensive building safety. Always check datasheets and manufacturer guidance to ensure suitability.
Frequently Asked Questions
Can fire retardant sprays be used on previously treated or painted fabrics?
Fire retardant sprays work best on clean, untreated, and absorbent surfaces. If the fabric has been previously painted, treated, or sealed, the spray may not absorb properly, which can reduce effectiveness. Always test a small area first, and contact the supplier for advice if you're unsure whether the surface is compatible with the product you intend to use.
Do these products affect the appearance or texture of the material?
Clear fire retardant sprays and liquid treatments are designed to preserve the original look and feel of the material. They dry invisibly and do not change colour, sheen, or texture when used as directed. However, on some delicate or dark fabrics, it’s wise to test a hidden area first to ensure compatibility and finish.
Can I use these treatments on outdoor materials?
Some fire retardant treatments are suitable for outdoor use, particularly on timber, but it's essential to select a product tested for weather resistance and non-leaching performance. Always confirm whether the treatment is suitable for external exposure, and consider using additional sealers or topcoats for added durability in harsh environments.
