PRESTONETT WOOD REPAIR

You need a filler formulated for wood, able to bond to this substrate and accept wood finishes. PRESTONETT WOOD REPAIR is a powder repair and filling compound for wood, for interior and exterior use. It can be applied at any thickness, becomes very hard once dry and remains sandable, with a fine finish. It can then be overcoated with interior or exterior paint, varnish or an undercoat.

Yes. The PRESTONETT WOOD REPAIR product sheet lists wood, chipboard and plywood as substrates, and priming them is good practice. Priming seals the absorbency of the wood, evens out the substrate and improves the durability of the repair. Without this step, the wood draws water out of the filler unevenly, which affects setting and adhesion. The substrate must also be sound, dry and free of dust.

Yes. PRESTONETT WOOD REPAIR can be tinted with a water-based dye. This is useful for bringing the colour of the repair closer to that of the surrounding wood, especially when the intended finish is a varnish rather than an opaque paint. It is essential to tint the full quantity needed in one go, because reproducing exactly the same shade in a second mix is very difficult.

Yes. PRESTONETT WOOD REPAIR can be carved, drilled and painted once dry. This is what sets it apart from a standard filler and makes it suitable for repairing joinery, mouldings and profiled sections. Very hard once dry, it can be worked like the surrounding wood. It also remains sandable, so the repair can be finished flush.

First remove any decayed or loose wood, then dust off and prime the substrate. Next, mix PRESTONETT WOOD REPAIR at 0.50 litres of water per kilo of powder, in small quantities as its working time is 35 minutes. Build the repair up slightly proud, then, once dry, re-form the corner by sanding or carving, as the product accepts both.

PRESTONETT WOOD REPAIR can be applied at any thickness, which makes it suitable for major repairs such as the bottom of a door or a damaged upright. Its consumption is easy to estimate: 1 kg of powder fills a volume of 1 litre. Very hard once dry, it can then be carved, drilled, sanded and painted. Its ready-mixed version, PRESTONETT WOOD FILLER, is limited to 1 cm thickness.

The working time of PRESTONETT WOOD REPAIR is 35 minutes. So mix small quantities, suited to the repair in hand, and never add water to a mix that is starting to harden. The mixing ratio is 0.50 litres of water per kilo of powder.

PRESTONETT WOOD REPAIR can be used indoors and outdoors. Outdoors, apply it to a sound, dry substrate that has been primed beforehand, then protect the repair from rain while it dries. The repair must then be overcoated; the product sheet lists conventional paint and primer as overcoats, and states that it can be painted, stained, varnished and waxed.
