Products formulated to fill, seal or repair cracks, holes and surface imperfections in a variety of substrates—such as wood, masonry, metal and drywall—restoring both the appearance and structural integrity of the material.
Common Sub-Categories & Examples:
-
Wood Fillers: Solvent- or water-based pastes that dry hard and can be sanded and painted (e.g. spackling putty, polyfilla).
-
Foam Fillers: Expanding polyurethane or acrylic foams for filling cavities, voids and joints; excellent insulation and sound-dampening properties.
-
Epoxy & Polymeric Putties: Two-component systems that bond to most surfaces, offering high strength and chemical resistance.
-
Cementitious Repair Mortars: Pre-mixed cement or polymer-modified mortars for patching concrete, brickwork and render.
-
Decorative and Flexible Sealants: Flex-grade fillers that accommodate slight movement, used around doorframes, skirtings and window reveals.
Key Characteristics to Consider:
-
Substrate Compatibility: Ensure the compound bonds to the intended material (wood, concrete, metal, etc.).
-
Cure Time & Workability: Open time and drying speed to suit the scale of the repair.
-
Sandability & Paintability: Ability to be smoothed and finished to match surrounding surfaces.
-
Flexibility vs. Hardness: Rigid fillers for structural repairs; flexible fillers where movement is expected.
These products enable professionals and DIYers alike to achieve seamless, long-lasting repairs across a wide range of home-improvement and construction projects.
