Avoiding Common Mistakes in Fire Retardant Spraying for Curtains and Fabrics

Updated: Dec 16, 2023

Introduction: The Importance of Fire Retardant Spraying for Curtains and Fabrics

Fire retardant spraying is an essential step in ensuring the safety of your house or business, but it is especially critical for textiles and curtains. The spread of flames in the case of a fire can be considerably delayed or avoided by spraying these materials with fire retardant, limiting property damage and saving persons from danger. This step not only provides safety, but it may also save time and money by reducing the severity of any possible fire. You may ensure that your house or business is as safe as possible by using fire retardant spraying.

The Dangers of DIY Fire Retardant Spraying

However, attempting to apply fire retardant spray on your own can be dangerous and ineffective. Using the wrong chemicals or not applying the spray correctly can lead to discolouration, shrinkage, or limited flame resistance in the fabrics, rendering them ineffective in case of a fire. Additionally, using too much chemical can leave a sticky residue on the fabrics, making them unusable. It is important to choose a professional fire retardant spraying service to ensure safe and effective treatment.

Fire Retardant Spraying for Natural Fabrics: Overcoming Shrinkage and Discoloration

When treating natural fibres with fire retardant chemicals, it's important to choose the right chemicals to avoid the pitfalls mentioned above. The chemicals are usually water-based and so tightening can occur, especially in linen. In fact, linen can actually sag when wet but normally tightens once dry.

Make sure to choose a chemical designed for natural fibres if the majority of the material is made up of natural fibres. Light colour natural cotton such as beige can lighten or bleach if treated and exposed to UV light. This can be minimised if dried indoors.

A fire retardant spraying specialist who understands the specific requirements of these types of materials will be best placed to advise you.

Fire Retardant Spraying for Synthetic Fabrics: Flaming Debris

Synthetic fabrics such as polyester or nylon are more resistant to fire than natural fabrics, but they can still easily catch fire. Once alight they give off noxious smoke and often drip flaming debris.

It's important to choose the right fire retardant chemicals for synthetic fabrics to ensure they maintain their flame resistance over time. To achieve a suitable level of fire resistance there is a risk of not using enough chemicals or using too much. The thickness of the material being treated will require different strengths of the solution.

Additionally, it's important to have them re-treated every 5 years or 5 dry cleans to ensure that their fire resistance remains effective.

Meeting Fire Safety Standards for Curtains and Fabrics

Curtains in the home are not required to comply with any fire standards and those purchased from retailers are not fire resistant. Contract curtains (curtains used in hotels, auditoriums, schools etc) must meet the standards set out in BS 5867.

Usually, fire retardants that are purchased have been tested by a UKAS-accredited testing house or an equivalent international body, to prove their products can meet BS 5867 Part 2 Type B. By applying these products competently the required fire standard can be met.

The Importance of Professional Fire Retardant Spraying Services

If you want to avoid as best possible all the pitfalls of DIY fire retardant spraying, the best course of action is to employ the services of a Fire Retardant Spraying Specialist. They should be aware of the latest materials, chemicals, techniques and the latest standard revisions.

Most importantly of all, they can provide you with a certificate of treatment which you may need for insurance purposes or to satisfy a fire risk assessor.

Conclusion: Ensuring Safe and Effective Fire Retardant

Spraying for Curtains and Fabrics

In conclusion, fire retardant spraying for curtains and fabrics can be of great benefit to those wanting extra protection for their homes and is a requirement for businesses serving the public. Although fire retardant can be purchased from retailers online there are many points to consider before DIY treatment. Considering everything and being methodical can yield good results. The most reliable and best results will come from using the services of a fire retardant spraying specialist.
