151 All Purpose Filler White 600G Interior Exterior USE Mixed Ready to USE
Best for versatile repairs, this ready-to-use filler is designed to resist sagging, cracking, and shrinkage after application. It dries white for a clean plaster or plasterboard finish, suitable for both indoor and outdoor projects. Use on brick, wood, stone, or plasterboard after cleaning and drying the area.

Buying Guide
What to consider when selecting ready mixed plaster
- Surface type: Choose products formulated for indoor walls, ceilings, or exterior patches based on where you’ll apply them.
- Finish and texture: For a smooth paint-ready surface, prefer fillers marketed as “smooth finish” or overpaintable.
- Drying time and workability: Ultra-fast dry fillers improve throughput but may require quicker application; slower sets can be easier for larger repairs.
- Sandability: If a seamless finish is essential, look for sands-ready formulations after curing.
- Compatibility: Check if the product is suitable for plasterboard, brick, wood, or metal, and whether a priming step is recommended.
- Environment: Outdoor or damp areas may need water resistance or extra sealing; ensure proper ventilation and surface dryness.
Practical tips for use
- Clean and dry the repair area before applying any filler.
- Apply in thin layers and sand between coats when needed to avoid cracking.
- Test a small inconspicuous area first to confirm bonding and drying behavior.
