Garage Door Painters in Lincoln

Timber garage doors need thorough preparation before any new paint can go on. We strip back to sound timber, sand the surface down, and fill any splits or deterioration with exterior filler.

Bare timber gets an oil-based or specialist exterior primer. Two coats of exterior gloss or satin follow as standard. Timber side-hinged and up-and-over doors are common on older Lincoln properties, particularly in and around the Cathedral Quarter where garages are often converted outbuildings.

Metal garage doors fail when the preparation is skipped. Surface rust is wire-brushed and treated with a rust converter before any primer is applied. A rust-inhibiting metal primer follows and is allowed to cure.

The common failures we see on metal doors across Lincoln — bubbling, rust bleed-through at the base and edges, peeling topcoat — are all the result of painting over a compromised surface. Lincolnshire’s damp autumn and winter climate makes metal doors on north and east-facing elevations particularly susceptible to corrosion.

GRP (glass reinforced plastic) is the most common composite garage door material, and is the default fit on newer properties across Nettleham, Branston, and Cherry Willingham. It cannot be painted with a standard primer — a specialist adhesion primer is required to bond to the smooth, non-porous surface.

Without the correct primer, the finish peels. The substrate itself does not need stripping — a thorough clean and degrease before priming is sufficient. A correctly primed GRP door takes a finish coat well.
