A ready mixed surface filler for interior repairs to walls and ceilings. No mixing, no mess. Skins in 30 minutes, fully cured in 24 hours. Fills up to 10mm per layer and accepts oil and water-based paints.
This 1kg ready mixed surface filler is the kind of thing you reach for without thinking — a tub on the shelf, a knife in your hand, job done. No powder to mix, no ratios to get wrong. It is a filling and sealing compound designed for internal use, covering the sorts of repairs that crop up on every decorator’s day: hairline cracks in plasterboard, nail holes, surface blemishes, and shallow chips in plaster walls and ceilings. The 1kg ready mixed surface filler is genuinely useful to have on site or in the van.
The formula skins over in around 30 minutes, which keeps your workflow moving. Leave it to cure fully — 24 hours is recommended — before sanding and painting. It fills up to 10mm in a single layer, so for anything shallower than that you are looking at one coat and done. Deeper repairs just need a second pass once the first layer has set, which is straightforward enough.
Once cured, the filler forms a flexible and waterproof seal, which matters in areas that see the occasional knock or where surfaces move slightly with temperature. That flexibility reduces the chance of the repair cracking back out, which is a more common issue with harder, more brittle fillers. It is compatible with both oil-based and water-based paints, so whatever your decorator is using over the top, this will sit happily underneath.
Where Ready Mixed Surface Filler Fits in Everyday Work
Decorators and plasterers use this filler for finishing work before painting, skimming new plasterboard edges, and tidying surfaces after chases have been filled in. It is not a structural product, but for cosmetic surface repairs in interior settings it does exactly what it needs to. The ready mixed format removes a small but genuinely irritating prep step from the job. No bag to open, no mixing bucket, no dust. Just open the tub, apply, and move on.
At this price and pack size it is an easy stock item. Keep a tub handy and you will use it regularly.
Pro Tip: Always wet your filling knife slightly before applying ready mixed filler to help it spread smoothly and prevent it dragging or pulling away from the surface, especially on dusty or porous plaster.
Ready mixed surface filler is used primarily by decorators and painters during the preparation stage, filling minor cracks, holes, and surface damage on interior walls and ceilings before painting or wallpapering. It works on plaster, plasterboard, concrete block, and painted surfaces. Plasterers use it for light finishing work and tidy-up repairs around chases, skirting lines, and door frames. General builders keep a tub on site for patching up after first fix trades have been through and left their marks behind.

Not suitable for: Not suitable for exterior use or structural repairs. Not recommended for filling deep voids in a single application as shrinkage may occur beyond 10mm depth.
Apply the filler directly from the tub using a filling knife or flexible spatula. Dampen the knife slightly for a cleaner finish. Press the filler firmly into the repair, slightly overfilling the surface to allow for minor shrinkage as it dries.
Allow the surface to skin for around 30 minutes before touching. Leave a full 24 hours before sanding back and applying paint. For deeper repairs above 10mm, apply in two layers, letting the first cure fully before adding the second. Always reseal the tub between uses to prevent the filler drying out.
Clean the repair area, removing any loose material, dust, or flaking paint
Dampen very porous surfaces lightly with water to improve adhesion
Load a filling knife or spatula with filler and press firmly into the crack or hole
Slightly overfill the surface to account for minor shrinkage during drying
Allow to skin for approximately 30 minutes before leaving to cure fully for 24 hours
Sand smooth once fully cured and apply primer or paint as required
Can I use this filler in a bathroom or kitchen?
This filler is rated for interior use and forms a flexible, waterproof seal once cured, so it can cope with occasional moisture. However, it is not designed for areas of constant water exposure such as wet room walls or shower surrounds. For those environments you would want a specifically rated waterproof filler or flexible sealant.
How much depth can this filler fill in one go?
It will fill up to 10mm per layer. For repairs shallower than that you should be fine in one application. Anything deeper just needs a second coat once the first has cured fully, which takes 24 hours. Trying to fill a deep void in one go tends to result in cracking as the outer surface dries faster than the material beneath.
This ready mixed surface filler is a water-based compound formulated for interior surface repair. The flexible binder reduces post-cure cracking and allows the repaired surface to move slightly without fracturing. It is compatible with both alkyd oil-based and acrylic water-based decorative coatings applied over the top. The product requires no on-site mixing and has a working consistency straight from the tub.
