How to Paint Internal Timber Shutters in London Georgian and Victorian Properties
The correct approach to preparing, priming, and painting internal timber shutters in London period properties — maintaining their function while achieving a durable, professional finish.
Internal Shutters: A Feature Worth Preserving Correctly
Original internal timber shutters are among the most sought-after features in London Georgian and Victorian properties. Folding back into panelled shutter boxes set within the window reveal, they provided draught exclusion, privacy, and security long before curtains became the default solution. In Belgravia, Mayfair, Marylebone, and across the Georgian streets of central London, these shutters survive in extraordinary numbers — often buried beneath accumulated paint layers that have, over generations, obscured their joinery detail and compromised their operation.
Painting shutters correctly means understanding their function as well as their appearance. A shutter that has been painted so many times that it no longer folds freely, or whose panels have been glazed solid with paint, is damaged in a meaningful way. The goal of a professional redecoration is to restore clean lines, preserve the movement of the shutter, and apply a finish that will last.
Assessment: What You Are Working With
Before picking up a brush, assess the condition of the shutters carefully. Several questions should guide the approach:
Do the shutters still operate freely? If not, is the cause excessive paint build-up, swollen timber, missing or seized knuckle hinges, or damage to the louvre mechanism? Paint alone will not fix a shutter that is mechanically compromised.
How many layers of paint are present? Run a finger along the panel moulding. On a shutter that has been painted every five years for a century, the moulding profiles will be partially obscured by accumulated paint. The depth and crispness of the profile determines whether the existing paint can be prepared in situ or must be stripped.
What is the current paint? Oil-based gloss has been the standard finish for shutters for most of their history. If the existing paint is lead-based — likely in any property built before 1960 and repainted without full strip-out — this has significant implications for preparation and disposal of waste.
Stripping: When It Is Necessary
Where paint build-up has compromised the operation of the shutter, obscured panel mouldings, or locked the louvre blades solid, chemical stripping is the correct route. A gel-type paint stripper applied in sections and removed with a broad scraper will remove multiple layers in a single application. On intricate moulded profiles, a shave hook — a pointed or swan-neck scraper — is used to work into the detail.
Louvre shutters require particular care during stripping. Each louvre blade is a small, separate timber element, and the mechanism that tilts them in unison is often fragile. Chemical stripper should be kept off the pivot mechanism where possible. If the pivot rod has been painted solid, it must be freed carefully — forcing it risks snapping the rod or cracking the individual blades at their pivot points.
Following stripping, sand back the timber with progressively finer grades — 80, 120, then 180 grit — finishing with the final grade across the grain as little as possible. Raise the grain with a damp cloth and allow to dry before a final 180-grit pass.
Priming Internal Shutters
Stripped timber shutters should be primed before any undercoat or finish is applied. The correct primer for bare timber joinery is an oil-based or alkyd primer — products such as Zinsser Bulls Eye 1-2-3 or a trade quality wood primer will seal the timber, provide a stable base, and prevent tannins in the wood from bleeding through the finish.
Apply primer to all surfaces, including the back face of the shutter, the edges, and the top and bottom rails. Unprimed timber that is exposed to changes in humidity will absorb moisture unevenly, causing the timber to move and the finish on the painted face to crack.
Allow the primer to cure fully — typically 24 hours at room temperature — before sanding lightly with 180-grit and applying the undercoat.
The Correct Finish
Shutters in London period properties are almost universally finished in white or off-white. The choice between a full gloss and an eggshell finish is partly aesthetic and partly practical. Full gloss is the traditional finish and gives the crisp, light-reflective quality that looks appropriate in a Georgian window reveal. It is also the most durable and washable.
Water-based eggshell or satinwood is an increasingly common alternative, particularly since legislation began limiting the VOC content of oil-based paints. The best water-based satinwoods — Farrow & Ball, Little Greene, or Dulux Trade Diamond Satinwood — give a finish that is difficult to distinguish from oil in normal use, with greater flexibility and easier clean-up.
Apply a minimum of two coats of finish, sanding lightly between coats with 280-grit paper. Keep paint away from the hinge knuckles; apply a thin bead around each knuckle with a small brush rather than rolling or brushing across it. Masking hinge pins with a small cone of masking tape before painting is standard practice.
Maintaining Shutter Movement
Once painting is complete, check the movement of each shutter panel before the paint is fully cured. If any panel binds, plane or sand the binding edge while the paint is still slightly soft. Waiting until the paint has fully hardened before discovering a binding edge means re-painting the planed section.
