Laser Paint Removal for Staircases & Architectural Joinery

Stripping a painted staircase by hand is one of the least profitable jobs in joinery. The detail that makes it worth restoring is exactly what makes it slow.

Staircases are where laser ablation makes the most obvious commercial sense in joinery, because the cost of the conventional method is driven almost entirely by profiles and detail, and a non-contact beam is largely indifferent to shape.

Spindles, turned newel posts, moulded handrails, string capping and decorative brackets all resist abrasives. An orbital sander cannot follow a turning. Detail sanding is slow and rounds over crisp arrises. Chemical stripping works but brings dwell time, residue in the grain and a lot of mess in what is usually an occupied house.

The realistic outcome

The objective is not usually a finished surface straight off the laser. It is:

  • Laser ablation to take the bulk of the coating off, including out of the profiles.
  • A reduced conventional preparation to bring the surface to the standard the finish needs.
  • Refinishing.

The saving sits in the first step. If hand-stripping a flight currently takes a week, and ablation takes the bulk of it off in a day with two days of finishing behind it, that is the business case, and it is one worth measuring on your own jobs rather than taking on trust.

Worth being clear about: Timber response varies by species, age, moisture and previous treatment, and older staircases usually carry many layers of different coatings. Test panels on the actual stair are how you find out what you are dealing with, not a general claim about staircases.

Working in an occupied house

This is often the deciding factor rather than speed. A dry, non-contact process with extraction produces a filter cartridge rather than sheeting, spent media, or solvent residue running down a hall. On a staircase in a house someone is living in, that difference decides whether the job is practical at all.

Which machine

The model for detail work

Joinery restoration is controlled removal on a variable natural substrate. That is the 300W brief.

Precision ablation LaserStrip 300W From £7,800 Controlled energy delivery for detailed work where preserving the substrate matters more than raw removal speed. Our 5 mJ configuration is the one to ask about for fine ablation work. View specification →

Standards and guidance

The rules this work sits under

A pulsed fibre laser is a Class 4 device. These are the primary UK sources, linked so you can read them rather than take our word for it. Measured results, including the combinations that do not work, are being published in the surface ablation database as tests complete.

Common questions

Questions we get asked

Can it be done in situ?+

The machines are mobile and the 200W to 500W run from a standard single-phase supply, so in-situ work is normal. You still need a controlled exclusion zone and extraction, because it is a Class 4 laser.

What about lead paint in a period property?+

Common on pre-1970s joinery. The removed material is captured by extraction and filtration rather than becoming airborne dust, which many contractors prefer to sanding, but it remains lead-bearing waste and must be handled and disposed of accordingly.

How many layers can it get through?+

It depends on the layers. Thin, dark, well-adhered coatings come off readily. A century of built-up oil paint may need enough passes that stripping the bulk another way and finishing with the laser is more economic. Testing tells you which situation you are in.
