Claims30
A method of reducing or preventing resin show-through in painted wood, the method comprising:
- impregnating unprimed, unpainted wood at a concentration of 8 to 50 g/m3 with one or more autoxidative catalysts in a liquid carrier before application of a primer coating to the wood, the one or more autoxidative catalysts comprising one or more metal compounds selected from one or more cobalt compounds, one or more manganese compounds, one or more cerium compounds, one or more vanadium compounds, or a combination of any two or more thereof, the liquid carrier comprising a water-based wood preservative, or a non-aqueous carrier, the wood being pine
- to reduce or prevent resin show-through in the wood after painting.
A method of reducing or preventing resin show-through in painted wood, the method comprising
- impregnating unprimed, unpainted wood by vacuum impregnation, pressure impregnation, or vacuum/pressure impregnation at a concentration of 8 to 50 g/m3 with one or more autoxidative catalysts in a liquid carrier, the one or more autoxidative catalysts comprising one or more metal compounds selected from one or more cobalt compounds, one or more manganese compounds, one or more cerium compounds, one or more vanadium compounds, or a combination of any two or more thereof, the wood being pine,
- the liquid carrier comprising a water-based wood preservative, or a non-aqueous carrier
- to reduce or prevent resin show-through in the wood after painting.

- applying a primer coating to the impregnated wood
- to reduce or prevent resin show-through in the wood after painting.
