What is tannin bleed and how is it prevented?

Here's the short answer:

Tannin bleed occurs when natural acids in timber migrate to the surface, causing dark stains or discolouration under the finish. Bona Prime Classic and Prime Intense prevent this. FSA Network floor sanders select the right primer to control tannin on species like Spotted Gum and Blackbutt. Prevention at floorsandingaustralia.com.

That's the basics. Give us a call if you need more detail.
