These are for creating a solid colour for your internal wood finish. For treating fresh wood we would recommend using the Osmo Creativ Range. For a VOC free quick drying paint use the earthBorn ProAqua Eggshell. Skirting can be most economically painted using the Green Paint semi-gloss. Excellent finishes can be obtained using the Auro 250 and 260 paints. The Auro, Green Paints and earthBorn paints can be used over existing paints, but will need to put onto a well prepared surface as they are all water based (Green Paints use soya oils and the Auro use citrus and linseed oils).
