Just sanded back a radiata floor and there are a number of blue stains in some of the boards. The stain was with each board, meaning the boards had the stain before they were laid.

The house is about 30 years old. If I had my guess the stain looks like some LSP treatment has leached into these floor boards before they were laid.

Any suggestions? I am worried about the finish binding to the stained bits
