Technical sheetDownload PDFPRESTONETT WOOD FILLER PASTE is a filling and smoothing compound specially formulated for wooden substrates indoors and outdoors. Ready-to-use, it offers a complete solution for repairing, filling and smoothing wood before finishing. Made in France by Beissier, this plaster-based filler combines ease of application with lasting performance for both tradespeople and discerning homeowners.
Substrates must be firm, cohesive, clean, sound and dry before application. The filler is applied directly with a putty knife or filling knife to areas requiring filling or smoothing. Thanks to its ready-to-use texture, no preparation is necessary.
For thicker applications, respect the 1 cm per coat limit. Once dry, the product can be sanded to achieve a perfectly flat surface. It can then receive an undercoat or finishing paint, as well as lightweight wall coverings.
The 60-minute working time at 20°C allows comfortable application, even over large surfaces. Allow complete drying before coating, depending on site humidity and temperature conditions.

For projects where you need to work on different wood species, consider tinting the filler slightly before application to harmonize the final colour, especially if you apply a transparent or translucent finish afterwards. On softwood or oily wood, light sanding beforehand significantly improves the filler's adhesion.
Professional tip: for deep repairs on external joinery, work in successive layers of maximum 5 mm rather than in a single thick application. This prevents shrinkage and cracking during drying, which is particularly important for wood exposed to climate variations in our Belgian regions.
Yes, this filler is suitable for all wood types, both indoors and outdoors. It can be applied to raw wood as well as previously painted or varnished wood, provided the surface is clean, dry and properly prepared.
Setting time is 35 minutes, but it is recommended to allow complete drying before sanding, approximately 3 hours for a thin coat. For thicker applications, wait longer depending on temperature and humidity conditions.
Yes, PRESTONETT BOIS PÂTE can be drilled once completely dry, allowing for later adjustments or fixings on repaired elements without risk of splintering.
Unlike universal plaster-based fillers, PRESTONETT BOIS PÂTE is specifically formulated for wood with natural materials. It offers better compatibility with wood movement and can be used outdoors, which traditional plaster fillers do not allow.
