Fillers

Learn more about fillers

Filling compounds ensure seamless surface restoration while eliminating paint flashing and suction marks on finished walls. Powdered and pre-mixed formulas key deeply into plaster, concrete, and masonry without sagging. 

Fibre-reinforced and flexible acrylic fillers across movement joints help prevent recurring cracks along door frames, skirting boards, and window surrounds through natural temperature shifts. 

Typical uses

Interior plaster and drywall repairs: Filling hairline cracks, nail holes, and deep impact hollows across plastered walls and ceilings.

Timber joinery and trim: Repairing damaged decorative wooden trims such as skirting boards, door frames, architraves, and window sills.

Exterior masonry and rendering: Sealing weather-exposed cracks and voids in concrete, brickwork, render, and stone.

How to choose the right filler

Matching the repair depth, surface location, and drying time ensures an efficient, crack-free finish:

• Ready-mixed vs. powdered fillers: Ready-mixed tubs offer convenience for minor patching and surface smoothing. Powdered fillers allow custom mixing ratios for deep repairs and dry rapidly across large surface areas.

• Interior vs. exterior filler: Use easy-sanding interior formulas for smooth plaster and drywall. Choose water-resistant, frost-proof exterior fillers for outdoor brickwork, stone, and rendered walls.

• Standard vs. flexible fillers: Select rigid fillers for static wall holes and flat plaster repairs. Use flexible, fibre-reinforced fillers around door casings, staircases, and window frames where structural movement occurs.

Before you order

• Check you have all the kit you need for the job, such as filling knives, sand paper and trowel.

• Confirm the size of the job to give a guide on how much filler you will need. Small tubs suit the odd crack or hole, while larger tubs or packs are better for repeated patching across a property or site.

• Allow a little for wastage so you do not run short mid-task.

• Review the drying time, paint-over time and application suitability before you order.
