  • Application and sanding: Choose products that offer easy spreading, minimal shrinkage, and quick sanding to speed up finishing.
  • Project size: Large repairs benefit from bigger containers; smaller fixes can use 6 oz tubes for precision.
  • Surface compatibility: Some fillers work on wood floors and trim; others are better for walls or outdoor furniture. Match to your surface type.
