Under Coat Problems
If the oil base stain and the paste wood-fillers are not completely dry before the lacquer goes on, it may look at first as if you are getting away with it. All will be well, but then a day, or a week, or a month, or a year later, you may notice a distinct greying of the lacquer which gets worse and worse and worse as time passes. This is called blooming.
Blooming takes place through the whole thickness of the finish coat. It can only be corrected by complete stripping and refinishing. Earl Stebbens, a finisher I used to know, told me that it happens because the oils are able to slowly penetrate the molecular matrix of the lacquer, turning it grey. Leave plenty of drying time for your stains and fillers.
The worst thing that ever happened to a good finish was lemon pledge. This and other spray polishes containing silicone make the furniture shiny and not smudgy. They make it glow and radiate warmth. Unfortunately, they also turn the lacquer to jelly within ten to fifteen years of regular use. They cut the life of a good finish in half, or even to a third of normal. They are the scourge and torment of every good re-finisher, because they settle into the wood. Stripper won’t touch them, sanding won’t remove them, they cause fisheeye. This is a situation where the lacquer simply flows away from spots on the wood surface like water off a duck’s back and will not stick there no matter how many coats of finish are sprayed. The result is a miniature moonscape of craters – a ruined finish.
