WHITE TIMBER PRIMER (PLUS TANNIN BLOCK)
Primer especially developed to inhibit tannin staining when painting over timber substrates. Works by means of chelation (precipitation), whereby soluble metal ions combine with the phenol groups in the tannins and render them insoluble. Usually top coat with 3015 or 3001.
