Overview:

Toupret Exterior Masonry Repair Filler is a cement-based exterior powder filler that bonds to both damp and dry rough masonry. It fills to any depth but without shrinking and does not require formwork. Apply it to cement, concrete, breeze blocks, bricks, or stone - on dry or damp substrates alike. The product withstands outdoor weather conditions once set, making it well-suited for year-round exterior repair work.

Mix at a ratio of 350ml of water per 1kg of powder (35%). Working time is 30 minutes at 20°C, giving a practical window for shaping repairs before the product hardens. The filler dries to a light grey colour and can be overcoated 48 to 72 hours after application with any standard water-based masonry or mineral paint.

Classified to BS EN 16566:2014 and an adhesion strength above 0.8 MPa (EN 16-566). VOC content is below 0.02%. The product is backed by a 6-month guarantee from the date of purchase when stored in its original sealed packaging, away from humidity.

Key Features and Benefits

• Damp or dry application: Bonds to both damp and dry rough masonry surfaces without loss of adhesion.
• No depth limit: Fills to any thickness in a single application - no need to build up coats.
• Shapeable repair: Can be formed and shaped by hand or tool, so formwork is not required.
• Weather resistant: Formulated for exterior use and able to withstand outdoor conditions once cured.
• No substrate sealing required: Apply directly to the prepared masonry surface without a prior sealing coat.
• Broad substrate compatibility: Suitable for cement, concrete, breeze blocks, bricks, and stone.
• 30-minute working time: At 20°C, offering time to shape and finish repairs before setting.
• Overcoatable in 48-72 hours: Compatible with standard water-based masonry paints and mineral paints once dry.
• Mixing ratio: 350ml of water per 1kg of powder (35%). 1kg fills 0.85 litres when mixed.
• Adhesion performance: Tested to EN 16-566 with adhesion above 0.8 MPa filler-to-substrate.
• Very low VOC: VOC content below 0.02%, meeting Directive 2004/42/EC requirements.
• 6-month guarantee: Product guaranteed from the date of purchase in original sealed packaging.

Typical Applications

• Deep crack and hole repair: Filling large or deep voids in exterior masonry walls in a single pass.
• Concrete and render repair: Patching spalled, cracked, or broken concrete and cement render surfaces.
• Breeze block restoration: Filling surface damage or holes in exterior blockwork.
• Brick and stone repairs: Restoring chipped, cracked, or eroded brickwork and stonework facades.
• Frost damage remediation: Repairing masonry surfaces damaged by freeze-thaw cycles.
• Pre-decoration preparation: Filling and levelling exterior masonry surfaces prior to painting.
• Shaped profile repairs: Rebuilding mouldings, edges, or shaped masonry sections without formwork.
• Patching damp walls: Applying to substrates that cannot be fully dried before repair is needed.

How to Use

• Surface Preparation: Remove all loose, crumbling, or unsound material from the repair area. The substrate must be hard, cohesive, and clean. Damp and dry surfaces are both acceptable.

• Mixing: Add 350ml of water per 1kg of powder into a clean container at room temperature. Pour the powder into the water. Stir thoroughly until the mix is smooth and free from lumps.

• Application: Apply the mixed filler using a filling knife, trowel, or blade. There is no depth limit - fill to the required thickness in one application without building up layers.

• Shaping: Shape and form the repair as needed before the product sets. Working time is approximately 30 minutes at 20°C. Ambient temperature and humidity will affect this window.

• Drying: Allow 48 to 72 hours before overcoating. This varies depending on coat thickness, substrate absorbency, and ambient conditions. Do not apply below 5°C or above 35°C, or at a relative humidity above 80%.

• Overcoating: Apply any standard water-based masonry paint or mineral paint once fully dry. Do not apply polyurethane or epoxy solvent-based paints directly - prime first with a water-based exterior paint.

Frequently Asked Questions (FAQs)

• Can this masonry filler be applied to damp or wet walls?
  Yes. This filler is specifically formulated for application to both damp and dry rough masonry. It bonds without loss of performance on wet substrates, rendering it suitable where full drying of the surface is not possible before repairs are needed.

• How long does Toupret Masonry Repair Filler take to dry before painting?
  The filler is ready to overcoat after 48 to 72 hours. The exact drying time depends on coat thickness, the type of substrate, and the temperature and humidity at the time of application.

• Is there a maximum depth or thickness for each application?
  No. There is no depth limit for this product. It fills to any thickness in a single application and does not require formwork to hold the material in place while it sets.

• What paints and coatings can go over this exterior filler?
  Any standard water-based masonry paint or mineral paint can be applied directly over the dried filler. Do not apply polyurethane or epoxy solvent-based paints without first priming the surface with a water-based exterior paint.

• What is the working time after mixing this masonry filler?
  Working time is approximately 30 minutes at 20°C. This is the window available for applying and forming the filler before it begins to set. Cooler temperatures may extend this slightly, while warmer conditions may shorten it.
