A model can be beautifully painted and still feel unfinished if the assembly is rushed. When assembling your Warhammer miniatures, clean preparation, careful adhesive choice, and thoughtful posing create a stronger result before the first layer of primer goes on. This is practical work, but it is also part of the miniature's final character.
Start With a Clean, Organised Work Area
Before removing a single piece from the sprue, review the instruction sheet and identify the components for the first stage of the build. Warhammer kits often use small, similarly shaped parts, and a quick check prevents a common problem: trimming two nearly identical pieces, then discovering one belongs to a later option or a different pose.
Work on a stable, well-lit surface with enough room to keep cut parts separate from the sprue. A shallow tray, sorting dish, or small containers make it easier to hold heads, weapons, shoulder pads, and other small components without sending them across the floor. Keep the instructions close, but do not assume the diagram shows every angle. Dry-fitting reveals much more than an illustrated step.
For most plastic kits, a basic assembly setup includes sprue cutters, a sharp hobby knife, a mould-line remover or fine file, plastic cement, super glue, and a sanding stick. The exact tool matters less than its condition. Dull blades tear plastic rather than cutting it cleanly, while worn cutters can leave stress marks at delicate contact points.
Removing Parts From the Sprue
Cut the part slightly away from the component rather than cutting directly against it. This leaves a small gate of plastic that can be trimmed and sanded flush afterward. Cutting too close with force can gouge a curved armour plate, bend a thin weapon shaft, or leave a pale stress mark that remains visible under paint.
Use a hobby knife with controlled, shallow strokes to remove the remaining gate. Always cut away from your hand and avoid trying to remove too much material at once. On rounded surfaces, a fine sanding stick can restore the contour with less risk than repeated knife work.
Find and Remove Mould Lines
Mould lines are the faint raised seams left where the two halves of the casting tool meet. They are easy to miss on bare grey or coloured plastic, especially on textured clothing, fur, cables, and armour edges. Once primer and paint are applied, however, they become more obvious.
Inspect every visible face of a component before gluing it in place. A dedicated mould-line remover is useful on broad plastic surfaces because it scrapes rather than cuts. A knife blade can do the same work, but use the back edge or a light scraping angle instead of carving into the part. On detailed areas, work slowly and preserve intentional sculpted ridges.
You do not need to pursue perfection on every hidden joint. The underside of a boot or the inside of a covered torso will not repay ten minutes of sanding. Focus your attention on faces, helmets, shoulder armour, weapon barrels, banners, large flat panels, and any area that will catch a highlight.
Dry-Fit Before Applying Glue
Dry-fitting means bringing the pieces together without adhesive first. It is the simplest habit that improves assembly quality. You can confirm orientation, identify gaps, test the balance of a pose, and see whether paint access will become difficult later.
This matters particularly with arms, weapons, and heads. A small rotation can change a model from stiff to convincing. On a character miniature, test the direction of the head against the weapon or hand position. A figure aiming, advancing, or looking toward another member of the unit can create a more deliberate visual rhythm on the table.
Dry-fitting also shows whether a part needs more cleanup. If two halves do not sit flush, look for a remaining sprue gate, mould-line buildup, or a locating peg that has not fully entered its socket. Do not force the pieces together. Pressure can distort thin parts and may leave a gap that is harder to correct later.
Choosing Plastic Cement or Super Glue
Plastic cement is generally the best choice for standard polystyrene Warhammer miniatures. Rather than acting like a surface adhesive, it briefly softens the plastic so the two parts fuse together. The resulting bond is durable and usually cleaner than a super-glue joint.
Apply a small amount to one contact surface, then press the pieces together. A little softened plastic may squeeze from the seam. On a simple armour join, this can be useful: let it set briefly, then carefully smooth it with a tool to reduce a hairline gap. Too much cement, however, can soften nearby detail and leave fingerprints or glossy damage.
Super glue is the appropriate choice for resin, metal, basing materials, and mixed-material conversions. It is also useful when a plastic part has been painted already, although assembling before painting is usually preferable. Super glue sets quickly, so dry-fitting becomes even more important. Use the smallest practical amount, especially on fine details where excess adhesive can frost or pool.
For heavier metal components or demanding conversions, pinning may be worthwhile. This involves drilling matching holes in both pieces and reinforcing the joint with a short length of wire. It is not necessary for most current plastic kits, but it remains a useful repair and conversion technique.
Build for Painting Access
A fully assembled miniature is not always the easiest miniature to paint. A shield held tight against a torso, a rifle crossing the chest, or a cloak wrapped around the body can block brushes from important areas. Consider which surfaces need clean painting before committing to every joint.
Sub-assemblies are separate groups of parts painted individually and joined later. They can be helpful for character models, vehicles, cavalry, or miniatures with deeply recessed interiors. A rider and mount, a backpack, a shield, or a weapon arm are common examples.
There is a trade-off. Too many sub-assemblies make handling, priming, and colour consistency more complicated. They also leave small unpainted connection points that need care during final assembly. Keep parts separate only when the completed model would genuinely prevent brush access. For rank-and-file infantry, a complete build is often the most efficient route.
If you plan sub-assemblies, test how you will hold each piece for priming and painting. Temporary mounting putty on a handle, cork, or painting grip works well for light parts. Avoid coating glue contact points with thick primer, since paint can weaken the final bond.
Filling Gaps Without Losing Detail
Not every seam needs filler. Many plastic joints disappear with careful cement application and light pressure. Larger gaps, especially around capes, shoulder joints, vehicle panels, or conversions, benefit from a modelling putty.
Use a small amount and press it into the gap with a damp sculpting tool, silicone shaper, or the tip of an old brush handle. Smooth the surface before the putty cures. It is easier to apply a thin second layer than to sand away a thick, uneven first application.
For armour, aim to continue the existing surface cleanly. For cloth, fur, or organic details, the putty can be textured while soft to match the surrounding sculpt. Take reference from the miniature itself. A seamless repair should support the model's form, not draw attention to the repair work.
Give the Base Equal Attention
A miniature's base is not an afterthought. It establishes stability, supports the pose, and gives the paint scheme a setting. Before gluing the model down, check that both feet sit naturally and that the miniature does not lean or rock.
You can keep bases simple with texture paint, sand, or a restrained painted finish, or build more narrative ground with cork, stones, debris, or sculpted elements. Keep in mind the practical needs of play. Tall scenic pieces can make storage difficult, and loose materials need to be firmly secured before priming and painting.
For units, repeated basing materials create cohesion even when individual models have different poses. A consistent earth colour, rock type, grass tone, or rim colour is often enough to make an army feel unified.
Inspect Before Priming
Once the adhesive has cured, inspect the miniature under strong light from several angles. Look for missed mould lines, visible sprue gates, fingerprints in softened plastic, open seams, and excess glue around details. This short inspection is much easier than correcting problems after a base coat reveals every surface.
Then wash your hands, remove sanding dust from the model with a soft brush, and move on to priming when the surface is clean and dry. At 2 Rockers, the same materials-first approach applies whether you are building your first unit or preparing a display piece: take the time to make the structure sound, and every later painting decision becomes easier.
