Weight: 5kg

Overview:

Toupret Exterior Tough Multi-Filler Fibre is a cement-based powder filler for exterior use, reinforced with fibres for added strength. It bonds firmly to a broad range of building substrates and handles filling, repairs, and localised skimming in a single product. This 5kg bag provides a workable batch life of 40 minutes and produces a white finish once fully cured.

The filler mixes with water at a ratio of 400ml per 1kg of powder (40%). It carries no depth limit for filling work, though a maximum of 5mm is recommended for skimming applications. Once dry, it accepts any standard water-based masonry or mineral paint after 24 hours - no pre-sealing of the substrate is required.

Toupret Exterior Tough Multi-Filler Fibre conforms to BS EN 16566:2014 and achieves a filler-to-substrate adhesion strength of over 0.8 MPa when tested to EN 16-566. The product is classified under NFT 36 005 as Family IV class 4c and is backed by a 6-month guarantee from the date of purchase, when stored in its original packaging away from moisture.

Key Features and Benefits

• Fibre-reinforced formula: Added fibres provide extra tensile strength over standard exterior fillers.
• Strong substrate adhesion: Achieves over 0.8 MPa adhesion strength, tested to EN 16-566.
• No depth limit: Suitable for filling at any depth - no formwork required.
• No substrate sealing needed: Apply directly to the prepared substrate without a primer or sealer.
• Paintable in 24 hours: Ready to overcoat with water-based masonry or mineral paint after an average of 24 hours.
• 40-minute working time: A generous open time allows comfortable application across larger areas.
• Wide substrate compatibility: Bonds to cement, concrete, breeze block, brick, stone, gypsum plaster, glass, glazed tiles, and old painted surfaces.
• Easy to sand: The cured filler sands smoothly without excessive effort.
• Low VOC content: VOC content below 0.05%, making it appropriate for use in most outdoor environments.
• Conforms to BS EN 16566:2014: Meets the standard for fillers used on internal and external building works.
• 6-month product guarantee: Guaranteed for 6 months from purchase, subject to correct storage conditions.
• Made in France since 1938: Manufactured by Toupret, a long-established specialist filler brand.

Typical Applications

• Filling and repairing cracks in exterior rendered or plastered walls.
• Patching holes and damaged areas in concrete and breeze block.
• Localised skimming of exterior wall surfaces prior to painting.
• Repairing mortar joints, brickwork, and stonework surfaces.
• Smoothing and levelling old painted exterior substrates before repainting.
• Filling and finishing glazed tile or glass surfaces for overcoating.
• Shaping and rebuilding exterior building details without the need for formwork.
• Exterior surface preparation on new or renovated building substrates.

How to Use

• Prepare the substrate: The surface must be hard, cohesive, clean, sound, and dry. Remove all loose material, dust, grease, and any flexible coatings. Follow standard trade preparation practices.

• Mix the powder: Add 400ml of water at room temperature per 1kg of powder (40% water ratio). Pour the powder into the water - not the other way around - and stir thoroughly until you have a smooth, lump-free paste.

• Apply the filler: Use a filling knife, trowel, or coating blade to apply the paste to the prepared substrate. For filling work, there is no depth limit. For skimming applications, a maximum depth of 5mm is recommended per coat.

• Work within the open time: Complete your application within the 40-minute working time. Do not add water to a batch that has begun to set, and do not rework material that is stiffening.

• Allow to dry: Leave the filler to dry fully before sanding or painting. Under average conditions, the surface is ready to overcoat after 24 hours. Drying times vary with coat thickness, substrate type, and ambient temperature and humidity.

• Overcoat: Apply any standard water-based masonry or mineral paint directly over the dried filler. If using polyurethane or epoxy solvent-based paints, first apply one coat of water-based exterior primer. Do not apply at temperatures below 5°C or above 35°C, or at relative humidity above 80%.

Frequently Asked Questions (FAQs)

• How long does Toupret Exterior Tough Multi-Filler take to dry before painting?
  Under average conditions, the filler is ready to overcoat approximately 24 hours after application. This may differ depending on coat thickness, substrate porosity, temperature, and relative humidity. Always check that the surface is fully dry and hard before painting.

• What is the correct mix ratio for this Fibarex filler?
  Add 400ml of water per 1kg of powder, which is a 40% water ratio. Always add powder to the water - not water to the powder - and stir until the mix is smooth and free of lumps.

• Does the substrate need priming before applying the filler?
  No priming or sealing is required before application. The substrate must simply be clean, sound, dry, and free of loose material. This saves time and resources on-site.

• Can this filler be applied to lime render?
  Yes, the filler can be applied to lime render provided the surface is hard, cohesive, clean, and dry. Follow standard trade preparation practices. If in doubt, apply a small test patch and assess adhesion before proceeding with a full application.

• Is Toupret Exterior Tough Multi-Filler suitable for use on glazed tiles?
  Yes, glazed tiles are listed as a compatible substrate. The surface must be clean and dry before application. Note that this product is formulated for exterior use - for internal tiled surfaces, check whether an interior-specific product would be more appropriate for your application.
