Fillers for Repairing Walls, Wood and Surfaces

Fillers repair holes, cracks and imperfections in plaster, drywall, wood and masonry. Selecting the correct product helps restore surfaces smoothly before painting or finishing.

Types and uses

There are lightweight spackling compounds for small interior holes, ready-mixed fillers for quick jobs, and two-part or solvent-based fillers for deeper voids and exterior use. Wood fillers are formulated to sand and stain, while flexible exterior fillers resist movement and moisture.

What to consider before buying

• Application surface: choose plaster filler for walls, specific wood filler for joinery and structural repairs for masonry.
• Drying and sanding: fast-dry fillers speed up projects, but allow adequate cure time for a durable finish.
• Paintability and stainability: ensure the product accepts paint or stain without visible differences.

Prepare the area by removing loose material and cleaning dust. Apply filler in layers for deep gaps, sanding between coats to achieve a smooth finish. For larger renovation projects, consider bulk tubs or trade packs; occasional shoppers may find good-value multipacks or clearance stock. Follow manufacturer safety notes, especially when using solvent-containing or powdered products. With the right filler and technique, you can restore surfaces to a near-original appearance ready for decoration.
