U-timber WPC boards are easy to take care of and don't need any paint. Tannin stains naturally occur in all wood species and sometimes migrate to the surface in composite decking where surface wood fibers are exposed to sun and water. Tannin stains may occur during or shortly after. Depending on the season this can take several weeks to several months. Once tannin stains disappear after the weathering process is complete, they do not re-appear. To hasten removal of tannin stains, use warm, soapy water or other commercial outdoor wpc decking cleaner and a soft bristle brush.
