Note, use of cornice/base as foundation and cornice on 4103, and solely as a cornice on 4102. Also note use of mid-wall trim on 4103 as a lower profile cornice over the freight door wall module


1 – GLUES:  MEK or equivalent for all wall/detail parts

                     Rubber Cement for window mylar

2 – TOOLS:  Razor saw or hacksaw, or if available, a table saw or band saw; 8-10” flat single cut file, mitre box, tape measure, try square and framing square.

BEFORE YOU BEGIN: The G WALLS modular walls and accessories are designed to give you a variety of options in assembling brick style buildings that suit the hobbyist’s own needs and desires. The modular nature of the product also allows the hobbyist to create a building which is different from other G WALLS buildings. The flexibility of the product means that some cutting of the accessory pieces may be necessary, and the modeler should give some thought to the final appearance of the building. To aid you in planning the layout of the building, Heritage Models provides a paper template of the wall sections and accessories on page four of the instruction sheet. Plan structures with photocopies of the template, a quick and easy way to develop a building.

 You should allow adequate time to prepare, paint and glue sub-assemblies of walls before gluing the walls together at corner joints. While you can handle pieces within ten minutes after joints have been made using MEK as the bonding agent, the bonds will be stronger if the sub-assemblies are allowed to sit undisturbed for several hours or overnight. If the hobbyist plans to build a large multi-story building or a building that is larger than a basic square (configuration), it is wise to plan to mount the building to some sort of base for ease of moving the structure while at the same time protecting the model. Finally, on some buildings or building fronts it may be necessary to add internal bracing.


1)  Lay out pieces determining the basic shape of the building, and then add the accessories. If you intend to mount your building to a bas, you may find it useful to lay out the building’s “footprint” using a square and drawing the plan on the base. This will also assist you later to ensure that the wall of the building is square while gluing the wall sub-assemblies together to form the building. If you intend to use the cornice/base section as a foundation for the building, decide whether the pilasters and/or corner pilaster sections will extend all the way to the ground or begin at the top of the foundation level.

2) Cutting the pieces with a hacksaw or razor saw will give clean cuts. If you use a power saw, use the finest blade available and use a moderate feed rate. Keep the brick face upward. Flash usually forms on the edges, this can be easily removed after it has cooled (a fine wire brush is handy). If necessary, finish the edges with a file.

3) When constructing multi-story structures, build each wall as a separate piece on a flat smooth surface. Use a framing square or try square to keep all parts aligned. The panels are accurately designed and molded, but careful work will give the most satisfying results. The pilasters and cornices may be longer than necessary, so measure and test-fit before cutting. Also, before cutting the pilasters, ensure that the brick lines on the pilaster will line up with the brick lines on the wall sections.

4) Test fit all pieces before gluing. Use generous amounts of glue on panels and connectors to give a strong bond. Apply glue to both mating surfaces and if necessary, support or lightly clamp the pieces to ensue that the mating surfaces are in full contact. Allow several hours for a full strength bond.

NOTE: Before gluing, note the glue manufacturer’s warnings on the MEK solvent type cement container, and follow their recommendations. Work in a well ventilated location and avoid breathing the glue vapours.

5) Before the roof is installed, you may wish to add right angle bracing on the inside corners of the structure at the roof level, using the bracing to support the roof in the corners. Some additional supports along the length of the roof should be added, using appropriate sized material.

6) PAINTING:  Easy painting can be done with automotive spray paints that are formulated for plastic. Use light strokes to prevent paint runs. Basic weathering can be achieved through overlays or blends of gray and black primers. Standard model railroad paints should be applied with an airbrush for most efficient results.
