Everything You Need to Know About Fire-Retardant Durability and French M1 fire rating Validity

In the professional sector, fire safety is a legal obligation involving your liability. When you decide to buy certified products for your materials (wood, textiles, cardboard, artificial plants), an essential question arises: is this fire-retardant treatment permanent?

At Alfaflor, experts in passive fire protection for over 30 years, the answer is yes: this treatment is permanent, provided the conditions of use are respected. Thanks to our product formulation, a single application by spray or roller is enough for the material to retain its M1 fire rating for life. This permanence is a decisive advantage for the sustainable management of your facilities and furniture.

Benefit from a Lifetime M1 Warranty for Your Interior Installations

The efficiency of our products provides your materials with protection that has no technical expiration date. Your fireproofing certificate is, therefore, a valuable document that does not require periodic renewal. However, for this “lifetime” guarantee to remain effective, durability is conditioned by two key factors you must master.

The Legal Factor: Official Test Report (PV) and Certificate of Application

It is essential to distinguish between the two crucial documents for your compliance that you will receive upon delivery:

• The Official Test Report (PV): This document, issued by an independent laboratory, certifies that the product in the canister is M1 certified. It is the proof of quality to be presented to the safety inspection body.
• The Fireproofing Certificate: This document is provided directly in your package. Once completed with the usage details (treated surface area, quantity used), we validate it with a signature and SNPI stamp. It proves the compliance of your installation as long as the product is not altered.

Adhere to Technical Conditions to Maintain Fire Protection

To maintain the benefit of the M1 rating over the long term, a few golden rules must be scrupulously respected:

• Avoid contact with water: Our fire-retardant products are water-soluble. If the material is washed or exposed to high humidity, the product washes away, and the protection disappears.
• Strictly Indoor Use: The lifetime warranty is reserved for indoor installations to protect the treatment from weathering.
• Protection against wear and tear: On friction zones (counters, carpets), mechanical wear can remove the product. For wood, applying a finishing varnish is recommended to protect the primary layer.

Textiles are the most sensitive materials because the natural reflex is to clean them. While our treatment is for life, it remains non-washable. To maintain your compliance, discover our guide: how to maintain fire-retardant fabric.

Successful Application to Guarantee Product Efficiency

Whatever the material treated, it is paramount to apply the correct quantity of liquid product to comply with safety standards:

• Wood: 1L treats approximately 6m².
• Cardboard: 1L treats approximately 4m².
• Artificial Plants: Use our specific conversion chart according to the volume of the plant.
• Textiles: The requirement depends on the surface area and the weight (GSM) of the fabric. The heavier the fabric, the more product is necessary.

Easy to apply, the treatment nevertheless requires rigorous precision.
