It's fisheye. The wood was somehow contaminated with a wax or silicone. The fix would be to sand it smooth and put another coat on with the paint being treated with a couple drops of Smoothie or an equivalent. Smoothie or some other fisheye control solvent can be obtained from a store that sells automotive paint. Another option would be to sand it smooth and repaint it in very thin coats until you get it covered.

There is no way to see it to tell if it's contaminated. The most common culprit is silicone. I worked for a company one time that was using silicone spray lubricant on their saw tops like a person would use paste wax. The silicone was getting on the wood from the saws and giving the painter heck. Maybe the lumber company or the saw mill used silicone on or around the wood and the overspray got on the wood. Anyway in more than 40 years of woodworking I've never gotten a board that was contaminated so what you have is not likely to happen again. Most of the time when you encounter fisheye it is when you are refinishing an old piece of furniture. Furniture polish like Pledge contains silicone and it goes through the finish and gets into the wood. You can wash the furniture down with a wax and grease remover, then chemically strip the furniture, sand it and the silicone will still be there. It's funny though the cure is to add silicone to the paint. That is what products like smoothie are made out of.

I think I clean down the timber with white spirit ever time when I done a product. So the paint has a clean wood to go on

If its a paint it should have had primer. If not the wood should have been sealed.

What was your surface preparation steps. What species of wood is it? Is it virgin wood or did it have a prior finish on it? If it was previously finished, what was the finish? How did you remove any existing finish?

What was the finish you applied?
