To avoid bubbles and pinholes on wood with worm holes, like this piece of wormy chestnut, apply a thin coat finish — thick finish, as pictured, traps air and causes bubbles. one coat per day. Be certain that each coat is dry before the next goes on. Follow this sequence, and odds are your finish will last a whole lot longer this time around. I'm starting a project building a plank table of wormy chestnut with grooves between the boards. I'm concerned about bubbles or pinholes developing during the finishing process over worm holes and nail holes. What would be a good finish choice? Jim Vallimont Coraopolis, Pennsylvania <9 For simply sending in his question on bubbles over worm holes, Jim Vallimont of Coraopolis, Pennsylvania wins UGL's ZAR Wood Finishing Kit. Each issue we toss new questions into a hat and draw a winner. Michael Responds: No matter what finish you choose, you avoid bubbles and pinholes by applying each coat sparsely and well-thinned. It is only when thick finish bridges over gaps such as worm holes that the trapped air attempting to rise causes bubbles. Thin finish applied sparsely will prevent that. If this is a kitchen or dining table, I would suggest oil-based polyurethane. You may thin it as much as you need to with mineral spirits. Bear in mind that thinner coats will help you avoid bubbles, but the corollary is that you'll need more coats to build it up. In other words, if you make it half mineral spirits and half polyurethane, plan to apply twice as many coats to get the same build. 457-55-546230 days FREE I'm Todd Davis, CEO of LifeLock, and this really is my social security number.* I'm here just to prove how safe your identity can be with LifeLock.
