How can I paint without brush marks?

I keep leaving brush marks when I use British Paints H2O Enamel. What can I do?

You might simply be pressing the brush down too hard as you paint. Once the paint has dried, lightly sand it down to get rid of the brush marks, and then apply another coat. Use a light but firm grip, and let the brush do all the work. You might also try loading the brush with a little less paint and painting a smaller area. This ought to allow the paint to stay wet for longer, and give it time to settle evenly.
