Fine surface filler vs multi-purpose filler

Updated: October 2026

Two white tubs look the same, and the mark in the plaster is either a hairline or a picture-hook nick. Fine surface filler vs multi-purpose filler is that choice. Fine paste feathers a hairline. Multi-purpose paste takes a nick up to about 10 mm, still in layers. In this set that is Palace 68-4 against the Polycell tube and Palace ready mixed 68-1. Pack size and the wider indoor or outdoor order are the [wall filler buying guide](/hub/fillers-adhesives-and-sprays/surface-filler/sub/surface-filler-buying-guide). The listings are on the [surface filler comparison](/hub/fillers-adhesives-and-sprays/surface-filler). Prices are from 15 October 2026, not a live re-check. The Products Compared editorial team did not run a lab test.

Fine surface filler is the feathered repair

Fine surface filler is the smooth ready-mixed paste for a crack you can feather to nothing. Toupret UK puts fine smoothing at about 2 mm, as context from a powder page, not as a score for Palace. Palace 68-4 is the fine paste kept here. The 600 g card is interior, and deeper repairs stay in layers of no more than 3 mm. Reviewers sand it on small holes, and several say it is the wrong tub for big holes. You can layer it. You should not use it as a one-pass deep filler. The two-pack is the same 68-4 at about £2.50, touch-dry in 1–2 hours, with the same review file. Buy the tub at about £1.25 for a few hairlines. Buy the two-pack for a room of them.

Multi-purpose filler is the everyday nick

Multi-purpose filler is the everyday tube for a crack or small hole up to about 10 mm. Polycell’s page says about 10 mm in one go, surface-dry in 1–2 hours, then more layers, on plaster, masonry, concrete, and brickwork indoors or outdoors. The 330 g tube at about £3.49 does not print that depth. The page does. The paste can be very thick. Palace 68-1 states the cap on the card: layers no thicker than 10 mm. It is 1 kg at about £6.99, interior, and it excludes exposed exteriors and continuous water immersion. Waterproof on a feature line does not cancel that. The data sheet of 28 October 2024 matches the times: skin in about 30 minutes, surface-dry in 1–2 hours, full cure up to 24 hours at 20°C. It names skirting and frames. Both pastes are ready-mixed. Both can shrink if you ignore the cap. Neither is automatically the outdoor tub.

Palace fine against Polycell and Palace ready mixed

If you cannot fit a fingernail in the crack, start with Palace 68-4. It is the best value on the main comparison at about £1.25, which is a price fact, not a test. The Polycell 330 g tube is the top pick there because of 14,595 reviews, and it is the small multi-purpose tube when the nick is deeper and you accept that depth and outdoor scope live on the manufacturer page. Palace 68-1 is the kilogram when the same interior job includes frames and you want the 10 mm cap printed on the card. 68-4 and 68-1 are not one Palace product in two sizes. The caps differ, and only the 1 kg tub writes the exterior exclusion. Among these three, only the Polycell page states indoor and outdoor use. A room of hairlines takes the two-pack at about £2.50. A room of 10 mm nicks takes the 1 kg tub.

When you want neither

Powder sets chemically and is Toupret’s contrast to ready-mixed shrinkage. It is not one of these three. A moving skirting gap wants flexible sealant, because a hard fill cracks when the joint works. A hole you can see through wants a patch. Plasterboard screws and taped joints are a different job from this versus. Polycell Exterior Polyfilla is a separate product and not in this set. Do not borrow FOME FLEX’s 30 minutes for Palace or Polycell. Do not claim fine paste shrinks less. Ready-mixed paste can shrink whichever family you bought, if the layer is too deep. You need both tubs only when the same room has hairlines and nicks near 10 mm. A qualifying purchase can earn a commission at no extra cost to you.

Common questions

What is the difference between fine surface filler and multi-purpose filler?
Fine filler feathers a hairline in thin layers. Palace 68-4 caps deeper repairs at 3 mm. Multi-purpose filler takes an everyday nick up to about 10 mm, on the Polycell page and on Palace 68-1, still in layers at that cap. Both are ready-mixed. Neither is a patch for a hole you can see through.
Will multi-purpose filler feather out on a hairline crack?
It can fill a hairline, and it is often coarser to feather than fine paste. One Palace 1 kg review calls the texture coarse, and one Polycell review says the repair grins through unless you prime. If you cannot fit a fingernail into the crack, start with fine surface filler.
Is Palace 68-4 the same job as Palace 68-1?
No. 68-4 is fine surface filler, interior, with a 3 mm cap, at about £1.25. 68-1 is 1 kg of multi-purpose filler at about £6.99, layers no thicker than 10 mm, and it excludes exposed exterior use. The review files differ too: 2,247 on the fine listings, and 4,537 on the 1 kg tub.
Which one can I use on wood and skirting?
Palace fine names timber, beams, and skirting. Palace 68-1 names skirting, architraves, and frames. The Polycell page names plaster, masonry, concrete, and brickwork, not a timber list. A skirting gap that keeps moving is still a sealant job, whichever paste you own.
Which one is for outside?
Among these three, the Polycell multi-purpose page states indoor and outdoor use. The 330 g card does not repeat that line. Palace 68-4 is interior. Palace 68-1 excludes exposed exteriors and continuous water immersion. A dedicated exterior filler is a different product and is not compared here.
