The Tannin Block Primer is a special resinous insulating primer for wood or wood products with a high content of tannins or pigments. It prevents the appearance of permeable discolorations mainly in transparent and white coatings. The special composition with a blend of active nanomolecular technology ingredients with water-based synthetic resins allows it to penetrate deeply into the wood to seal its tannins, thus preventing staining.

ADVANTAGES

• Protects wood from staining by tannins and other extracts.
• Extends the life of coatings (varnishes – paint varnishes) by maintaining the finish color for a long time.
• Prevents potential blistering from the action of protective impregnation materials.
• Excellent penetration.
• Easy application.
• Environmentally and user-friendly.
• For interior and exterior use.
