Top ten tips when applying varnish:
- Wait until your painting is completely dry.
 - Choose a dust free area to work in, keeping windows and doors closed.
 - Use a flat, wide, soft and tightly packed varnishing brush. Keep it clean and use it only for varnishing.
 - Keep the work to be varnished flat on a table or work surface – avoid working vertically.
 - Stir the varnish well and pour it into a clean, flat saucer or tin. Load your brush, then wipe it on the side of the saucer so it is not dripping.
 - Apply the varnish in one to three thin coats, rather than one thick coat.
 - Use long, even strokes from top to bottom, moving gradually from one side to the other. Remove any bubbles.
 - Avoid going back over areas that you’ve done. For any areas you’ve missed, simply allow the piece to dry completely and revarnish.
 - After you’ve finished, shield the work from dust with a protective plastic film – known as a “tent”.
 - Leave to dry for 24 hours. If a second coat is required, apply it at a right angle to the first.
