3D printed gnomes arrive with clean, vibrant PLA colours and sharp details straight from the printer. For many collectors, that factory finish is exactly what they want. But for others, a 3D printed gnome is a canvas — a starting point for personal expression through painting, weathering, and creative customization.
Whether you want to add realistic eyes to a gnome’s face, weather a fantasy warrior for a battle-worn look, or completely repaint a piece in your own colour scheme, this guide walks through every step from surface preparation to final sealing.
Surface Preparation: The Foundation of a Good Paint Job
Skipping surface preparation is the single most common mistake when painting 3D printed figurines. Paint adhesion on untreated PLA is poor — the smooth, slightly waxy surface causes paint to bead up, streak, and chip off with handling.
Cleaning
Start by washing the gnome in lukewarm water with a small amount of dish soap. This removes any surface oils from handling, dust from storage, and mould release residue. Use a soft toothbrush to gently scrub crevices — beard details, hat folds, and tool handles collect manufacturing residue that prevents paint adhesion.
Rinse thoroughly with clean water and allow the piece to air dry completely. Do not use hot water, as temperatures above 50 degrees Celsius can begin softening PLA.
Sanding (Optional)
For the smoothest paint finish, light sanding with 400 to 600 grit sandpaper reduces visible layer lines. Sand in circular motions, applying minimal pressure to avoid removing fine details. Focus on broad, flat surfaces like robes, hats, and bases where layer lines are most visible.
For gnomes with intricate detail — densely textured beards, scaled armour, detailed accessories — skip sanding in those areas. The layer texture actually adds visual depth that enhances the painted finish in detailed regions.
Priming
Primer creates a uniform surface that accepts paint evenly and dramatically improves adhesion. Use a spray primer designed for plastic — automotive primer or hobby miniature primer both work excellently on PLA.
Apply two to three light coats rather than one heavy coat. Heavy primer applications obscure fine details. Allow 15-20 minutes of drying time between coats. Grey primer works as a neutral base for most colour schemes. White primer brightens transparent and light colours. Black primer creates naturally shaded recesses.
Choosing the Right Paint
Acrylic paint is the best option for PLA figurines. It adheres well to primed surfaces, dries quickly, cleans up with water, and produces no harmful fumes during indoor painting sessions.
Hobby acrylics from miniature painting brands (Citadel, Vallejo, Army Painter) are formulated specifically for small figurines. They have excellent pigment density, flow properties, and come in a wide colour range including metallics and washes. These are the professional choice for detailed work.
Craft acrylics from general art supply stores (Apple Barrel, FolkArt, DecoArt) are more affordable and available in larger bottles. They work well for base coating and broad colour areas. For fine detail work, thin craft acrylics with a small amount of water to improve flow.
Spray paint covers large areas quickly for base coats. Use spray paint only on primed surfaces and in well-ventilated areas. Keep the can moving to prevent drips and pooling in recesses.
Painting Techniques for Gnome Details
Base Coating
Apply your primary colours first in thin, even layers. Two thin coats always look better than one thick coat. Allow each coat to dry fully before applying the next — typically 15-30 minutes for acrylics.
Start with the largest areas: the robe or body, the hat, the beard. Use a medium-sized brush (size 2-4) for broad surfaces and switch to smaller brushes for edges and boundaries.
Detail Work
Once base coats are dry, move to smaller brushes (size 0 or 00) for faces, eyes, accessories, and fine trim. Steady your painting hand by bracing your wrist against the table edge. Breathe evenly and work slowly — rushing detail work is the primary cause of painting frustration.
For eyes, start with a white base, allow it to dry, then add a tiny dot of colour for the iris, and an even tinier dot of black for the pupil. This three-step approach creates surprisingly lifelike eyes even at small scale.
Dry Brushing
Dry brushing is the easiest technique for adding realistic texture to beards, fabric folds, and rough surfaces. Load a brush with paint, then wipe most of it off on a paper towel until the brush is nearly dry. Lightly drag the brush across raised surfaces. Paint catches only on the highest points, creating natural highlights that add three-dimensional depth.
This technique is particularly effective on gnome beards. Dry brush a lighter shade over a darker base coat to create individual hair texture with minimal effort.
Washing
Washes are thinned paint (roughly one part paint to four parts water) that flow into recesses and crevices, creating shadows and definition. Apply a dark wash — brown, black, or dark grey — over a completed paint job to add depth and bring out sculpted details.
Washes transform flat-looking paint jobs into dynamic, professional-quality finishes. A single wash application over base-coated gnome adds more visual depth than an hour of additional brushwork.
Customization Beyond Paint
Paint is the most common customization method, but creative collectors push further.
Basing adds context to a gnome display. Glue the gnome to a small wooden disc or stone slice, then build up a ground texture with model railway grass, miniature flowers, tiny pebbles, or scenic snow. A based gnome tells a story and looks dramatically more finished than a figure standing on its own flat base.
Kitbashing combines parts from multiple figures. Add a different hat to a gnome body, swap accessories, or combine elements from different prints. Hobby knife trimming plus super glue or epoxy creates custom combinations that no one else has.
Weathering adds realism to fantasy and outdoor gnome themes. Lightly sponge brown and grey paint onto lower sections to simulate mud. Dry brush metallic silver onto weapon edges to show wear. Add tiny spots of green or brown wash to simulate moss or age. These finishing touches make a gnome look like it has been guarding a garden for decades.
Accessory additions expand the narrative. Miniature tools, mushrooms, lanterns, or animals from model railway or dollhouse suppliers add scene-setting elements that complement the gnome design.
Sealing Your Finished Gnome
Sealing protects your paint job from handling wear, dust accumulation, and UV fading. This step is essential for any painted figurine that will be displayed or handled.
Matte sealant produces a flat, non-reflective finish that looks natural and organic — ideal for gnomes displayed in garden or natural settings.
Satin sealant adds a subtle sheen that enhances colour vibrancy without looking glossy. This is the most popular choice for display figurines.
Gloss sealant creates a shiny finish appropriate for metallic details, gemstones, or wet-look effects. Many painters use gloss selectively on specific elements (eyes, jewels, metal) while sealing the rest of the figure in matte or satin.
Apply sealant in light spray coats, holding the can 25-30 centimetres from the surface. Two thin coats provide better protection than one heavy coat. Allow 24 hours of curing before handling.

Frequently Asked Questions
Do I need to prime a 3D printed gnome before painting?
Yes. Primer dramatically improves paint adhesion on PLA surfaces and creates a uniform base that accepts colour evenly. Without primer, acrylic paint will bead up on the smooth PLA surface and chip off with handling. Two light coats of plastic-compatible spray primer are sufficient.
What type of paint works best on PLA figurines?
Acrylic paint is the best option. It adheres well to primed PLA, dries quickly, cleans up with water, and produces no harmful fumes. Hobby miniature paints from brands like Vallejo or Citadel offer the finest pigment quality for detail work, while craft acrylics work well for larger areas and base coats.
Can I paint over the existing PLA colour or do I need a white gnome?
You can paint over any PLA colour after proper priming. The primer coat creates a neutral surface regardless of the underlying colour. For the most accurate colour representation, use grey or white primer under lighter paint schemes and dark primer under darker schemes.
How long does a painted gnome last?
A properly primed, painted, and sealed gnome lasts indefinitely under normal indoor display conditions. The sealant layer protects against handling wear, dust adhesion, and minor environmental exposure. For painted gnomes displayed outdoors, reapply sealant annually and inspect for wear at the start of each season.
Will sanding remove the fine details from my gnome?
Light sanding with fine grit sandpaper (400-600) reduces layer lines on broad surfaces without affecting sculpted details. Avoid sanding intricate areas like beards, facial features, and small accessories — the layer texture in these areas actually adds visual depth. Focus sanding on large flat or curved surfaces like hats, robes, and bases.
