Do’s and don’t’s on varnishing

Varnishing is one painting job that seems to give many home workers trouble. It should be realised thqt varnish is made to suit different types of work—both interior and exterior—so be careful to select the correct type for the job. A flat brush, 2J inches wide, is most suitable for general work. Flick the bristles through

your fingers to remove dust and loose hairs, then wash in turpentine and rinse in clean, lukewarm water. When working indoors it is essential that no dust is allowed to float in the air.

Keep all doors and windows closed to avoid draughts. Never varnish on a damp or humid surface. This often causes the surface to “bloom” or fog over.

Always apply varnish in thin strokes. Overloading the brush can cause wrinkles. Never add oil or thinners to varnish, as it ruins drying qualities.

Varnish should not be stirred but poured gently into a pot. Allow any air bubbles to subside before using. Bubbles often appear if the surface is "daubed” with the brush, so always keen the brush on the surface and work with the tip, brushing as lightly as possible.
