Varnishing
When I paint using solvent based varnish why do I get tiny bubbles? And how do I remove them?
With the solvent based varnishes, MM14 MM15 and MM29, you will only get bubbles if you are very aggressive with your brushing....slow down ....take your time....and enjoy the cathartic experience!....and you will get less/no bubbles.
Also, do not shake the tin before using. The MM14 gloss varnish should only need to be gently rolled on the table, while the MM15 matt and MM29 satin varnishes need to be stirred well with a clean stick.
Finally, do not use a foam brush as it will tend to 'dissolve' over time (with the solvent based vanishes.
To remove any persistent bubbles, gently blow on them while the varnish is still wet. Use a straw to direct your breath if it doesn't seem to be working.
Once the varnish is dry, you can use a very fine grade wet and dry sandpaper - at least 800 grit, to lightly sand your varnish before applying the second coat. Don't forget to remove any dust this causes before reapplying your next coat of varnish.
If all else fails, this varnish is strippable. The varnish re-dissolves in mineral turpentine which has no effect on Matisse acrylic paints; thus a painting may be completely cleaned and re-surfaced without affecting the paint. However, if you have not used Matisse acrylic paints, please check with the manufacturer before trying this.
