What will be an ideal response?
Woods fall into two general groups: close-grained, such as maple, and open-grained, such as oak and walnut. When finishing these woods, a filler is applied to achieve a smoother final surface. Close-grained woods are smooth and use a liquid filler to seal surface pores. Some varnishes act as liquid fillers. Open-grained woods have visible open pores that must be filled with a paste wood filler to achieve a smooth surface.?
