White Limba Can Trap Its Neighbor’s Sanding Dust White Limba’s pale color and coarse, diffuse-pored texture make it vulnerable in contrasting turnings: fine dust from adjacent dark woods can lodge in its pores and leave a muddy gray cast. Practical takeaway: Make clean final cuts and minimize sanding. Seal the White Limba before sanding a contrasting assembly, then vacuum or blow away dust between grits. Test the complete finishing process on scrap first.
