MPN: TTFIBA10GB

Barcode: 3178310018675

Colour: White (when dry)

Weight: 10kg

Overview:

Toupret Exterior Tough Multi-Filler is a fibre-reinforced powder filler for exterior use. It handles filling, repairing, and localised skimming across a wide range of building substrates. Made with cement, selected mineral extracts, binders, and fibres, it bonds strongly to both painted and unpainted surfaces.

No surface sealing is required before application. Mix 400ml of water per 1kg of powder, then apply with a filling knife, blade, or trowel. There is no limit on application depth, making it well-suited to repairs of any size.

Once applied, the filler dries to a white finish and accepts overcoating in approximately 24 hours. It works with any standard water-based masonry or mineral paint. For polyurethane or epoxy solvent-based paints, apply a water-based exterior primer first.

Key Features and Benefits

• Fibre-reinforced formula: Glass fibres add strength and help resist cracking on exterior substrates.
• Excellent adhesion: Achieves an adhesion strength of over 0.8MPa to the substrate (EN 16-566).
• No substrate sealing needed: Apply directly to the surface without a primer or sealer coat.
• No depth limit for filling: Fill repairs of any thickness in a single pass; maximum recommended depth for skimming is 5mm.
• 40-minute working time: Allows sufficient time to place, spread, and finish the filler on site.
• Ready to overcoat in 24 hours: Paint with any water-based masonry or mineral paint after full drying.
• Wide substrate compatibility: Bonds to gypsum plaster, cement, concrete, brick, stone, glass, glazed tiles, breeze blocks, and old painted surfaces.
• Easy to sand: Sands back smoothly once dry for a clean, flat finish.
• Overcoat with any product: Compatible with any filler, paint, or wall coating.
• Coverage of 1.1kg per m² at 1mm: Allows straightforward material planning on site.
• Dries white: Provides a clean, neutral base for painting.
• Conforms to BS EN 16566:2014: Meets the standard for fillers used in external works.

Typical Applications

• Exterior wall repairs: Filling cracks, holes, and damaged areas on outside walls before painting.
• Localised skimming: Smoothing uneven patches on exterior substrates up to 5mm depth.
• Concrete and cement repairs: Patching spalled or damaged concrete and cement render.
• Brickwork and stonework: Filling surface defects on brick and stone facades.
• Breeze block surfaces: Filling voids and surface irregularities prior to decoration.
• Multi-material substrates: Repairing areas where different building materials meet, including gypsum plaster, tiles, and painted surfaces.
• Pre-paint preparation: Levelling exterior surfaces ahead of masonry paint application.

How to Use

• Preparation: Remove all loose material, dust, grease, and non-adherent coatings. The substrate must be hard, clean, cohesive, and dry.

• Mixing: Add 400ml of water per 1kg of powder (40% ratio). Pour the powder into the water at room temperature and stir until fully smooth.

• Application: Apply the mixed filler with a filling knife, blade, or trowel. There is no depth limit for filling repairs. Maximum recommended depth for skimming is 5mm.

• Second coat (if required): Apply the next coat as soon as the first coat is hard and dry to the touch. Working time is approximately 40 minutes per mixed batch.

• Sanding: Once fully dry, sand back to achieve a smooth, even surface. Always wear a dust mask when sanding.

• Overcoating: Apply water-based masonry or mineral paint after 24 hours. If using polyurethane or epoxy solvent-based paints, apply a water-based exterior primer first.

Frequently Asked Questions (FAQs)

• How long does Toupret Exterior Tough Multi-Filler take to dry before painting?
  The filler takes approximately 24 hours to dry before overcoating. Actual drying time depends on coat thickness, substrate type, temperature, and humidity levels on the day of application.

• What is the mixing ratio for this exterior filler?
  Add 400ml of water per 1kg of powder - this is a 40% water ratio. Pour the powder into room-temperature water and stir until the mix is smooth and lump-free.

• Can this Fibarex filler be used on painted exterior surfaces?
  Yes. The product bonds to both painted and unpainted substrates, including old painted surfaces, provided the existing paint is hard, sound, and non-flexible.

• Does exterior filler need a primer or sealant before application?
  No. This product does not require substrate sealing prior to application on most standard exterior surfaces. The substrate must still be clean, dry, and free of loose or friable material.

• What temperature conditions are needed for applying exterior filler?
  Apply at temperatures between 5°C and 35°C. Do not use when the relative humidity exceeds 80%. Cold, hot, or very humid conditions affect drying time and adhesion.
