Which material is used to fill pores and imperfections on wood after conditioning?

• A. Sandpaper
• B. Varnish
• C. Wood fillers (bouche-pores)
• D. Paint

Answer: (C)

Filling pores to create an even, smooth surface before applying the final finish is the idea here. After conditioning, wood pores open and small imperfections may show up, so a wood filler is used to fill those voids and micro-cracks. This gives a uniform surface that absorbs stain or finish evenly and helps the final coat lay down smoothly. Sandpaper smooths the surface and removes raised grain, but it doesn’t fill pores. Varnish and paint are finishes that seal and color the surface, not the primary pore-filling step, though a good filler often precedes them. So the material that fills pores and imperfections after conditioning is wood fillers.
