Gyproc Filler is a gypsum-based setting material primarily used in drywall construction and renovation for filling, jointing, and providing a smooth finish on various surfaces before painting or decorating.

Its main applications include:

Jointing Plasterboards: It is designed for filling the gaps (joints) between gypsum boards, often used in the initial (bulk) and secondary stages of the traditional jointing process, usually in conjunction with a jointing tape.

Covering Imperfections: It effectively covers screw heads, minor dents, and other small surface imperfections on walls and ceilings.

Patching and Repair: It is used for patching cracks and holes in existing plaster, concrete walls, and ceilings.

Skimming Surfaces: It can be used for skimming entire gypsum ceilings, drywall partitions, concrete walls, and fiber cement boards to create a smooth, paint-ready surface.

Adhesive for Moldings: Some formulations are also used as an adhesive for fixing gypsum cornices, fiber PU cornices, and other gypsum-based moldings.

Key Characteristics

Gypsum-based: It is a setting type material, meaning it hardens through a chemical reaction rather than just air drying, allowing for a relatively quick setting time (e.g., 60-90 minutes of working time before setting).

Low Shrinkage: The low-shrink formula helps reduce the risk of cracking, resulting in a durable and long-lasting finish.

Smooth Finish: It dries to a hard, smooth finish that is easy to sand, providing an ideal base for paint or wallpaper.

Strong Bond: It adheres firmly to gypsum boards, masonry, and plaster surfaces.

Note on Usage: Some specific Gyproc products, such as Gyproc Joint Filler, are intended only as filling products (stages one and two of jointing) and should be finished with a final coat of a finishing product like Gyproc Joint Cement or an Easi-Fill product for the best results. Always check the specific product instructions for optimal application.
