Owatrol Oil to protect exposed timber
Owatrol is like a WD40 for oil paints in that it drives out moisture from the surface being painted.
For instance on wooden cills, the recommended treatment prior to painting is as follows:
Remove all peeling paint down to a sound surface. Prime the bare wood with wet on wet coats of neat Owatrol Oil until no more is absorbed. 20 minutes after the last application wipe off any excess that has not penetrated. Allow to dry overnight; then prime and paint as usual. Add Owatrol Oil to the coating if using an oil or alkyd based primer or paint to ease application and aid adhesion.
Minus the scraping, this is how I propose to prepare bare softwood fencing for painting.
It has been exposed to the elements for a few months since being installed and now the weather is less rainy, it has come time to paint it. By saturating the pores with Owatrol and driving out the moisture, further coats should have a good chance of adhering to the surface.
I will use an oil based Sikkens microporous paint as well, just to further reduce the chances of moisture causing the film to bubble when the sun eventually shows its shy face round this way! Will keep you posted. Pardon the pun.
(This post from Plush Painting explains why you shouldn’t apply in this case, water-based paints over damp surfaces.)
Owatrol oil on metal
This shows how effective it is at keeping rust at bay on rusty drainpipes. Applied neat over cleaned-off rust, then added to further coats of oil based undercoat and gloss, Owatrol is the reason why the paintwork is still immaculate 2 years on.
You can ask Gary or Ken from Owatrol questions about their whole product range, direct from their Traditional Painter page in our Trade Corner. Alternatively, you can ask them an open question on our Owatrol forum where expert decorators will probably also chip in with their views as end users.
