Silver paint has a high metallic sheen that causes it to dry unevenly when it is applied incorrectly. This particular colour also tends to cover wood poorly unless the surface is treated with the right primer. If the wood isn't primed correctly, it will reject the silver paint.
Apply masking paper, sold in brown rolls at paint and home-improvement stores, to surfaces immediately beneath and adjacent to the wood, using painter's tape.
Coat the wood with a tinted latex primer, using a 2- to 4-inch paintbrush. Use a nylon brush on a coarse wood surface. Use a polyester brush on a slick wood surface. Brush with the wood grain, using gentle pressure. Allow the tinted primer to dry for two hours.
Rinse the brush with clean tap water.
Coat the wood with silver latex paint, using a clean brush. Brush vertically, using gentle pressure. Allow the tinted paint to dry for two hours.
Use an silver acrylic paint on wood surfaces subject to duress. Use a primer with a blue tint. Don't use a grey-tinted primer, as you will have a hard time assessing how well you've covered the wood. Do not use white, untinted, primer either, as it is insufficient for silver.
Once you begin applying the silver paint, continue until the entire surface is coated. Do not take breaks, as this will allow some of the silver finish to dry and cause the final finish to look uneven.
