Technical sheetDownload PDFPrestonett T.REX by Beissier is a high-strength powder fibre-reinforced filler, specially designed for all external repair work. Ideal for filling large holes and cracks over large surfaces, it offers a 3-in-1 solution that levels, fills and repairs in a single application. The formulation contains natural materials and benefits from environmental certification.
Prepare the filler by mixing the powder with clean water until a homogeneous, lump-free consistency is achieved. The product works easily and provides excellent adhesion on pre-cleaned and degreased external surfaces.
Apply the filler in successive coats if necessary for larger filling jobs. Thanks to its fibre-reinforced structure, T.REX resists mechanical stress and climate variations typical of our regions. Once dry, the filler is easily sandable to achieve a perfectly smooth surface, ready for your chosen finish.
Warning: this product contains cement. Wear appropriate protective gloves during application and avoid inhaling dust. In case of eye contact, rinse thoroughly with water.

Pygmalion advice: The Prestonett T.REX stands out for its ability to be applied in substantial thickness, up to 40 mm in a single pass, which avoids tedious multi-layer work on deep repairs. For projects in Belgium, account for our climate conditions: avoid applying the filler in frost or extreme heat, and protect freshly filled surfaces from rain during drying. The fibred texture ensures excellent mechanical strength, particularly valuable on facade corners exposed to impact.
This filler can be applied to a wide range of exterior substrates: concrete, autoclaved aerated concrete, cement, concrete block, brick, plaster and plaster derivatives, glass mosaic, stone, lime-cement mortar, as well as old paint finishes. Ensure substrates are clean, dry and free of loose parts before application.
Prestonett T.REX allows application of up to 40 mm thickness in a single pass, making it particularly effective for major repairs and filling deep defects without requiring multiple applications.
You can apply a second coat after 2.5 hours drying time. For coverage with paint or finishing layer, wait for complete drying, which is 24 hours. Respect these timeframes to guarantee optimal adhesion and prevent delamination.
For filling holes and cracks: allow approximately 0.7 kg of powder to fill 1 litre of volume. For surface build-up: plan approximately 1 kg per m². A 15 kg bag therefore allows you to treat approximately 15 m² for build-up or fill a substantial volume depending on your needs.
Yes, this filler possesses water-resistant and microporous properties. It resists moisture whilst allowing the substrate to breathe, which prevents condensation and premature degradation issues on exterior facades.
