Best sander for skirting boards UK: match the tool to your profile

For most UK skirting, a detail sander is the right tool. Its triangular pad gets into internal corners and along the top edge, where a square plate cannot. A sheet or orbital sander is faster on long, plain square-edge runs, and a belt sander is the wrong machine for this job at almost any price. What decides it is the shape of your skirting and the age of the paint on it, not the wattage printed on the box. Both are covered below, with current UK prices.

Start with the shape of your skirting

The profile of your skirting decides how much of the job a machine can actually do, and how much you will finish by hand. A flat sanding plate can only touch a flat surface. Every curve, groove, and arc on a moulded board is a place the pad bridges over instead of sanding.

Seven profiles cover most UK housing stock. The shape descriptions below come from Selco’s skirting range, which sells all seven and defines each one.

The common mistake here is shopping by power rating. A 250W sander does not reach into an ogee groove any better than a 100W one, because the limit is the shape of the pad, not the motor behind it. If you have moulded skirting, assume an abrasive sponge or folded paper will do the decorative section regardless of what you spend, which is also what Norton Abrasives recommends for contoured areas.

Worth knowing: if you cannot identify your profile, look at the board end where it meets a door architrave. The cut end shows the full section clearly.

Before you switch anything on: when was the house last painted?

If your skirting has original paint from before the early 1980s, do not put a power sander anywhere near it until you have checked for lead. This is the one part of the job where the tool choice is a health question rather than a finish question.

The Health and Safety Executive’s guidance on old lead paint sets the dates out plainly. Lead pigments were widely used in paints for homes, schools, and offices until the 1960s, and were not removed from commonly used paints until the early 1980s. A pre-1980s house with original woodwork paint under later coats is a realistic candidate.

Do not dry sand paint that might contain lead. HSE names dry sanding, along with stripping with blow lamps or gas torches, as a high-risk method. Breathing or swallowing lead dust or fume can cause kidney, nerve, and brain damage, or infertility. HSE’s recommended route for deteriorated paint is a combination of chemical paint stripper, wet abrasive paper, and on-tool extraction. If you use a hot air gun or infrared equipment instead, set it below 500°C. Wash hands and forearms before eating or drinking.

That guidance points away from a sander and towards a chemical route, which is covered in our guide to matching a chemical stripper to the age of the paint on pre-1980s woodwork. Lead test swabs are sold in most UK decorating merchants and take a couple of minutes to use, which is a reasonable price for ruling the question out.

Later houses, or skirting that has been replaced at some point, are a different situation. Modern paint on MDF or softwood is a straightforward sanding job.

The three sander types that suit skirting, and one that does not

A detail sander is the default choice for skirting, because its triangular pad is the only common pad shape that fits an internal corner. Skirting is full of internal corners, and the alternative is finishing every one of them by hand.

• Detail sanders, also sold as delta or mouse sanders, use a triangular hook-and-loop pad with a point at the front. They are small, light, and cheap. The trade-off is speed. Bosch’s specification for the PSM 100 A gives a sanding surface of 104 cm² running at 26,000 orbits per minute with a 1.4mm orbit, on a 0.9kg body. That is a small pad moving in small circles, which is exactly what you want near a corner and slow going across a long wall.
• Sheet and orbital sanders take a rectangular pad and cover ground faster. They suit long, plain, square-edge runs and are the better call in a hallway of straight boards. They cannot get into a corner, so most people end up owning both or accepting hand work at every internal angle.
• Oscillating multi-tools take a delta sanding pad as an accessory. If one is already in the cupboard, fit the pad and try it before spending anything. Sanding is a secondary function on that tool rather than its purpose, so a dedicated detail sander will be more comfortable over a full room, but the reach is the same.
• Belt sanders are the wrong tool here, and it is worth being blunt about it because they get recommended surprisingly often. A belt sander removes material fast in a straight line, which on a 15mm-thick moulded board means flattening the profile you were trying to keep. On anything other than plain square-edge boards laid flat on a bench, it turns a decorating job into a joinery job.

What is on the shelf in the UK right now

We have not tested these machines. This comparison is built from manufacturer specifications and UK retailer listings, all linked, with prices checked at Screwfix on 18 August 2026. Prices move, so treat the figures as a guide to the tier rather than a quote.

Under £35

Full listings: Screwfix detail sanders and Screwfix sheet sanders.

The Bosch is the one with a usable feedback trail behind it. Its Screwfix listing carries a 4.7 out of 5 rating from 54 customer ratings, alongside a 10m cable, a 102 x 102mm plate, and a one-year guarantee. A 10m cable matters more than it sounds on a skirting job, because you are working at floor level around a room perimeter and an extension lead underfoot is a nuisance.

Cordless, if you already own the batteries

Every price above is for a bare tool. Adding a battery and charger to a platform you do not already own roughly doubles the outlay, which is why a £16 corded Titan beats a £29.99 cordless one for a single room unless you are already invested. The Milwaukee kit with batteries is listed at £228.99, for comparison.

When it is worth spending more

Two cases justify it. The first is a large house where you will be sanding for days rather than hours, where a brushless motor and better vibration damping are a comfort purchase that pays off. The Skil SR1U7280DA at £54.99 sits at the top of the corded range at 250W.

The second is if the sander will keep earning its keep after the skirting is done. A Makita DBO382 or Milwaukee M12FDSS is a tool you will still be using in five years. For one weekend of skirting, that is money better spent on abrasives and a decent extraction hose.

The last 20mm nobody talks about

No sander in the list above reaches the bottom of a skirting board while the board is on the wall. The body of the tool sits proud of the pad, so the pad stops somewhere between 10mm and 20mm short of the floor. That strip is exactly where the old paint is thickest and most visible once the room is finished.

There are three honest ways round it, and the right one depends on how much you care about the result.

• Accept it and hand-sand the bottom strip. A folded sheet of 120 grit and a few minutes per wall. Slow, but it works and costs nothing.
• Lift the boards off the wall. This turns an awkward in-situ job into a comfortable bench job where every edge is reachable and the dust goes on a dust sheet rather than into the carpet. Skirting is usually pinned or glued and comes off with a bolster and patience. Working at waist height on a portable workbench also means the delta tip reaches the profile properly for once. The cost is making good the wall afterwards.
• Replace rather than restore. If the boards are already damaged, or you are lifting the floor anyway, new skirting is often less work than saving forty years of paint build-up. If new flooring is part of the plan, the order matters, and our guide to fitting flooring before the skirting goes back on covers the sequence.

Internal corners have the same problem in miniature. A delta pad reaches into the angle but the point wears out fastest, so order the triangular sheets in quantity rather than one pack.

The dust box on the sander is not enough

The onboard dust box on a detail sander collects a fraction of what the tool produces, and the rest ends up in the air of a room you are about to redecorate. Connecting the sander to a vacuum through its extraction port is the single change that makes the most difference to how the job feels.

Which vacuum matters more than most guides admit. Dust extractors are graded by class, and the difference between M-class and H-class is not a marketing tier. M-class filters trap over 99.9% of dust and are the right grade for wood, MDF, and board materials. H-class traps over 99.995% and is what is required where the dust may contain lead.

That maps straight onto the previous sections. Modern paint on MDF skirting is an M-class job. Suspected lead paint is an H-class job, and per HSE, one that should not involve dry sanding at all.

The common mistake is reaching for the household vacuum. A domestic cleaner is not filtered for fine construction dust and will push the finest particles, the ones that stay airborne longest, straight back into the room. HSE’s construction dust guidance lists on-tool extraction and respiratory protective equipment as the controls that actually work, and the reason is that regularly breathing this dust is linked to lung cancer, asthma, and COPD.

A disposable mask, safety glasses, gloves, a dust sheet, and an open window are the minimum, which is also Norton’s list for this job.

Grit sequence for painted skirting

Start at 80 grit on painted skirting, work up through 120 and 150, and finish at 240 if the boards are going to be topcoated in gloss or satin. Norton’s guidance is to use 80 to 120 grit for deep scratches and paint removal, 120 to take off rough edges, 150 for finishing, and 240 to leave a smooth surface.

Suppliers disagree on where to start. Skirting World’s guide suggests 40 to 60 grit for stripping old paint, which is a lot more aggressive. On softwood or MDF that is a fast way to put gouges into the board that then need filling, so 80 is the safer opening on anything you intend to keep. Drop to 60 only where the paint build-up is genuinely thick, and only on the flat face.

The sugar soap step is the one people skip. Sanding through greasy paint clogs the abrasive within a minute, and a clogged sheet burnishes the surface instead of cutting it.

Three mistakes that cost people a weekend

• Sanding before checking the paint’s age. Covered above, and worth repeating because it is the only mistake on this list with a health consequence rather than a cosmetic one.
• Skipping the wall above the board. Skirting sits against plaster that is usually in worse condition than the board. Sanding the skirting to a fine finish and then discovering the wall above it needs work means masking and dust twice. If the wall is coming into scope, our guide to sanding and filling walls back flat is worth reading first.
• Sanding paint that is already lifting. A sander will not fix an adhesion failure underneath. It removes the loose top layer, leaves a sound-looking surface, and the new coat lifts in the same place a few months later. Where paint is flaking rather than simply tired, dealing with the flaking properly comes before any sander comes out.

FAQs

Do you need to sand skirting boards before painting?

Yes, if the existing finish is gloss or satin, because new paint will not key to a shiny surface. Norton’s guide puts a sugar soap wash before the sanding stage, and the sanding itself only needs to dull the sheen rather than take the board back to bare wood.

Can you sand skirting boards without taking them off the wall?

Yes, and most people do. The two limits are the bottom 10mm to 20mm, which no sander body will reach while the board is fitted, and internal corners, where only a triangular pad gets close. Lifting the boards solves both and creates a making-good job in exchange.

What grit should you use on painted skirting boards?

80 grit to cut back the paint, then 120 and 150, then 240 before the topcoat. Sources differ on the coarse end, with some suppliers suggesting 40 to 60 grit for heavy paint build-up, which is more aggressive than most softwood or MDF skirting will tolerate without gouging.

Is a multi-tool with a delta pad as good as a detail sander?

For reach, yes, since the pad shape is the same. For comfort over a full room, no, because sanding is an accessory function on a multi-tool rather than what the tool is designed around. If you already own one, fit the pad and test it on a metre of skirting before spending anything.

Can you sand skirting boards that have lead paint?

Not dry. HSE names dry sanding as a high-risk method for old lead paint and points instead to chemical stripper, wet abrasive paper, and on-tool extraction. Test first if the house predates the early 1980s and the woodwork paint looks original.

Do you sand skirting before or after the floor goes down?

Sand and paint the skirting before the final floor covering wherever the sequence allows, because it removes the risk of dust and paint on a new surface. Where the skirting is staying put and the floor is being replaced around it, the order flips and the bottom edge needs masking instead.
