BIRD BRAND 1328 White Knotting 250ml is a liquid solution for sealing knots in bare timber before applying paint or varnish. It is designed to inhibit resin and sap from seeping through, which can cause discolouration of light-coloured finishes.
This product is commonly used on joinery, architraves, and window frames, both indoors and outdoors. Its white finish supports the application of pale paints by providing a neutral base, and the 250ml container is appropriate for focused touch ups or smaller jobs on site.
