Can I apply Restol™ Wood Oil on top of other coatings?

Restol™ Wood Oil is designed to be applied to untreated or treated wood. In general, Restol™ Wood Oil will not work effectively if applied on top of existing paint or stain. Therefore we do not recommend this. We suggest that you first fully remove the old coating. Restol™ Wood Oil can then be applied in the usual way.

How should I prepare the surface prior to applying Restol™ Wood Oil?

Hardly any surface preparation is required. Give it a stiff brushing, always ensuring that the final surface is dry and free of dust. If you want an extra smooth result, you should give the surface a light sanding. Preparation takes no time at all.

Can Restol™ Wood Oil be used on badly weathered and damaged surfaces?

Restol™ Wood Oil is ideal for this as well. No special surface preparation is required either. Simply remove loose items with a (wire) brush and ensure that the surface is free of dust. You can also use a high-pressure spray to clean the surface.

Do I need to sand in between coats?

This is not mandatory. If an extra smooth result is required, you should give the surface a light sanding. This can also be achieved by using a scourer pad. This will achieve the required result in no time.

Can I treat impregnated wood with Restol™ Wood Oil without further preparation?

Yes, this can be done providing the wood is sufficiently dry. If your garden wood is still slightly moist, we recommend that you let it dry for a few weeks. This will give an even better surface on which to apply Restol™ Wood Oil.

How long does Restol™ Wood Oil usually take to dry?

To a degree this depends on the surface type, temperature and humidity. Usually it will be touch-dry in around 6 hours and can be over-coated after 1-2 days.

How long should I stir the product if it has been standing for an extended period of time?

If Restol™ Wood Oil is left standing, the heavier ingredients will settle to the bottom of the can. It is always important to stir Restol™ Wood Oil well, especially as the bottom is invisible from the top. The length of stirring should be in proportion to the length of time the can has been left standing. One minute should be used as a rule of thumb. The product will have been stirred sufficiently when the stirring device can be scraped over the bottom with little or no resistance, and the surface of the Restol™ Wood Oil is evenly coloured.

How many coats of Restol™ Wood Oil should I apply?

We recommend two coats on impregnated wood and three coats on all other wood. Ultimately, the decision to apply an additional coat depends on the end result – the surface of the wood should appear to be evenly coated with Restol™ Wood Oil. If you’re not satisfied, apply a top coat. When applying by brush or roller, always do so along the length of the wood (i.e. with the grain) for the best results.

Can I use Restol™ Wood Oil indoors?
