General and Multi-Purpose Fillers

General and multi-purpose fillers are everyday essentials for smoothing out cracks, covering screw holes, and restoring surface imperfections across plaster, wood, masonry, and more. Suitable for use before painting or wallpapering, these fillers come in ready-mixed or powdered formats to suit the job at hand. Designed for ease of sanding and compatibility with most decorative finishes, they are a reliable choice for both quick fixes and more detailed repair work. For  filling larger cavities or irregular gaps, specialist foams may be more suitable for construction or insulation tasks.

General and Multi-Purpose Fillers for Professional Repairs


Used across building, decorating, and repair trades, general and multi-purpose fillers are relied on for internal and external surface preparation. These essential building supplies offer practical solutions for patching cracks, evening out rough areas, and preparing substrates for coatings or coverings. Suitable for use on timber, plasterboard, concrete, and brick, they are a staple in domestic and commercial maintenance kits.

Where specific filler grades are required to meet safety regulations, fire-rated fire stopping fillers are available to help seal joints, service penetrations, and construction gaps, limiting the spread of fire, smoke, and heat through walls, floors, and ceilings.

General and Multi-Purpose Filler FAQs


Can multi-purpose fillers be drilled into after drying?

Yes, many general-purpose fillers can be drilled once fully cured, though care should be taken to avoid brittle edges.

Are these fillers resistant to mould or damp conditions?

Some formulations include mould-resistant additives, but always check if the product is rated for humid or wet environments.

Do they adhere well to previously painted surfaces?

Most will bond well to painted substrates, provided the surface is clean, dry, and free from loose material.

Can I use them on floors as well as walls?

These fillers are typically designed for vertical or overhead surfaces. For floors, choose a floor-rated levelling compound instead.
