Rustins Grain Filler is a professional-grade paste filler designed to fill open pores in timber before polishing, varnishing, or lacquering. It ensures a smooth, level surface and prevents finish sinking, giving your woodwork a flawless, professional sheen.
Supplied as a ready-to-use paste, it can be thinned with white spirit for easy application. The Natural shade can be tinted using Rustins Wood Dye, allowing you to fill and stain in one operation — ideal for efficiency and colour control on furniture and fine joinery.
Available in Mahogany, Natural, Oak, and Teak, this filler is suitable for all open-grain woods, including oak, mahogany, ash, and walnut.
