Fatrafol 807v is a polyester-reinforced PVC roofing membrane with a non-woven fleece backing, made for fully adhered single-ply flat roof systems. The reinforcement carries the loads; the backing takes the adhesive.
UV resistant and rated to EN 13956. It is a professional system product: adhered installation needs trained contractors with the right adhesives and detailing stock.
Frequently asked questions
What is Fatrafol 807v designed for?
Fatrafol 807v is specifically designed for adhered roofing systems. Its non-woven PES-textile backing ensures a secure bond to suitable flat substrates, providing reliable waterproofing for roofs.
Can Fatrafol 807v be used on bitumen surfaces?
No, Fatrafol 807v is not suitable for direct adhesion to bitumen surfaces. Using it on bitumen will compromise the bond and the waterproofing integrity.
Is this membrane suitable for mechanical fastening?
No, Fatrafol 807v is not designed for mechanical anchoring. It is engineered for adhered applications where the membrane forms a full bond with the substrate.
What product should be used for detail work with Fatrafol 807v?
For all detail work, Fatrafol 804 is required. This ensures consistency and performance across the entire waterproofing system.
Substrate guide
Proper substrate preparation is critical for the long-term performance of any adhered roofing system.
Flat substrates (fibre-cement, vibrated concrete)
Surface prep: Substrates must be clean, dry, sound, and free from loose material, dust, oil, grease, and curing compounds. Any unevenness should be smoothed or filled to prevent damage to the membrane.
Primer: Required. A suitable primer for PVC membranes should be used to enhance adhesion, as Fatrafol 807v is specifically designed for adhered systems. Consult Fatra for recommended primer options and application rates.
Existing waterproof layers (heat-treated)
Surface prep: Ensure the existing surface is fully cured, clean, dry, and free of any contaminants or damage that could inhibit adhesion. Compatibility with the existing layer must be verified.
Primer: Required. A compatible primer must be applied to ensure a robust bond to the existing waterproofing. Consult Fatra for specific recommendations for your existing membrane type.
