Door casing refers to the decorative molding or trim that surrounds a door, serving both functional and aesthetic purposes. This architectural element is typically installed on the interior sides of door frames and is designed to conceal the joint between the wall surface and the door jamb. Door casing comes in various styles, ranging from simple and streamlined to more elaborate and ornate, depending on the desired aesthetic of the space.

Base molding, also known as baseboard or skirting, is a trim element that serves both functional and aesthetic purposes in interior design. Typically installed at the junction of the wall and the floor, base molding adds a finishing touch to a room by concealing the joint and providing a transition between the vertical wall surface and the horizontal floor. Base moldings come in a variety of styles and profiles, ranging from simple and straightforward designs to more intricate and ornate patterns, allowing homeowners to choose a style that complements the overall aesthetic of the space.

Primed boards refer to wooden boards that have been pre-coated with a layer of primer, a paint undercoat that enhances adhesion and promotes a smoother finish when the boards are painted. These boards are commonly used in construction and interior finishing projects, offering a convenient and time-saving solution for those who prefer a pre-primed surface. The primer applied to the boards creates a sealed and uniform base, helping to prevent the absorption of paint and ensuring that the final coat adheres evenly. This not only streamlines the painting process but also contributes to a more professional and polished look.

Interior finish boards encompass a variety of wooden boards and trim elements used to add the final touches to the interior of a space, contributing to both functionality and aesthetic appeal. These boards can include baseboards, crown molding, chair rails, and other decorative trim components. Often made from materials such as wood or MDF (medium-density fiberboard), interior finish boards serve to conceal joints, transitions, and edges in a room, providing a cohesive and polished look. They can be chosen in a range of profiles and styles, allowing homeowners and designers to customize the visual character of a space. Interior finish boards are commonly used around doors, windows, and along the junctions of walls and floors, creating a finished and harmonious appearance.
