0:10 Hi There. I'd like to talk to you about varnishing oil paintings. Varnishing will protect your paintings from dust and pollution and can improve their appearance. You should wait at least 6 months before varnishing the painting, regardless of what medium you've added to your oil paint. You can test whether the painting is ready, by rubbing a cotton bud moistened with Sansodor against a discreet area of the painting. If no colour is transferred, it is safe to varnish the painting.
0:40 Before varnishing, you should gently wipe the paintings surface to remove dust. This microfibre cloth will remove but not create dust. This varnish brush is perfect for the job. I'm using this bowl as it is wider than my brush. I'm applying the varnish smoothly and in one direction until the painting is coated. Now I'm laying off the stroke to ensure an even coating. Apply just one layer of varnish, otherwise the result will be very patchy.
1:44 Look at the improvement in saturation by using gloss varnish. Satin Varnish has slightly matted the surface on this panel where the use of a resinous medium, such as Liquin, has created a higher gloss than wanted. Matte Varnish has made this surface easier to read, by completely taking away the high-gloss. Make sure that Matte and Satin Varnishes are thoroughly stirred to disperse the matting agent, otherwise you'll end up with a glossy surface. Matte and Satin varnishes tend to take a while to dry down to a matted surface so don't panic.
2:30 So, you can protect and enhance the look of your paintings and choose the level of sheen. If you're not confident about your brushwork there are spray versions available of all the varnishes that I've shown you. I hope this has helped you understand varnishing.
