Putty Chalk

Superfine Putty Chalk Powder (Whiting Powder) is Calcium Carbonate based powder used as an extender/Spreader that helps make the wall look smoother. It is primarily used to fill in cracks and holes in walls/ Wood to prepare an even Smooth surface before applying paint. Superfine putty chalk powder can be used as a wood filler. When mixed with water or oil primer, it creates an effective filler for small cracks, holes, or imperfections in wood. The chalk powder helps to absorb and fill the voids. This makeshift wood filler can then be sanded down and painted over once dry. (However, for larger or more structural repairs, a commercial wood filler product specifically designed for that purpose may provide better, longer-lasting results).
