What does hard decoration include

Hard decoration refers to the fixed decoration parts that cannot be moved or removed in indoor decoration, mainly involving the basic structure, functional layout, and installation of fixed facilities of the house. The following are the main contents usually included in hard decoration, classified and explained according to the decoration process and spatial functions:

1、 Basic Engineering

Wall renovation:

Dismantle or construct new walls, adjust spatial layout (such as renovating walls other than partition walls and load-bearing walls).

Wall reinforcement and repair (such as repairing walls after slotting).

Ground treatment:

Grassroots leveling (cement leveling, self leveling construction).

Ground waterproofing (waterproofing coating construction in areas such as bathrooms and kitchens).

2、 Hydroelectric renovation (core of concealed engineering)

Waterway renovation:

The laying and installation of water supply pipes (hot and cold water pipes), including main and branch pipes.

Layout and fixing of drainage pipes (floor drains, toilets, washbasins, etc.).

Circuit modification:

Strong electrical system: conduit laying of wires (lighting, sockets, air conditioning circuits, etc.), installation of distribution boxes, and line grouping.

Weak current system: pre embedded pipelines such as network cables, telephone lines, TV lines, etc., and installation of switch socket bottom boxes.

3、 Wall engineering

Grassroots treatment:

Wall leveling, repairing cracks, and removing existing inferior putty or coating layers.

Apply interface agent (to enhance wall adhesion).

Decoration construction:

Scrape putty (usually 2-3 times) and polish flat.

Brushing latex paint or tiling (such as tiling walls in kitchens and bathrooms).

4、 Ceiling engineering

Ceiling base layer:

Build a suspended ceiling frame with light steel keel or wooden keel and fix it to the ceiling.

Ceiling finish:

Install ceiling panels made of gypsum board, aluminum buckle board (commonly used in kitchens and bathrooms) or other materials, and reserve positions for lighting fixtures and ventilation openings.

5、 Ground engineering

Tile/Floor Laying:

Tile laying (in areas such as kitchen, bathroom, living room, etc.), including leveling, tiling, and joint filling.

Wood floor base treatment (such as keel laying, moisture-proof film installation) and floor paving.

Special Ground:

Self leveling flooring, epoxy flooring (suitable for industrial or commercial spaces), etc.

6、 Installation of fixed facilities

Kitchen and bathroom facilities:

Kitchen: Installation of cabinets and cabinets (non removable fixed cabinets), installation of sinks and drainage pipes.

Toilet: Installation of fixed sanitary ware such as toilets, washbasins, bathtubs, shower bases, etc.

Door and window engineering:

Install anti-theft doors, indoor doors (such as wooden doors, aluminum alloy doors), windows (bridge cut aluminum, plastic steel windows, etc.), door frames, and window frames.

Other fixed devices:

Customized wardrobe and shoe cabinet installation (embedded in walls or fixed on the ground).

Laying and fixing of radiators and underfloor heating pipes.

7、 Waterproof and Soundproofing Engineering

Waterproof construction:

Apply waterproof coating to areas such as bathrooms, kitchens, balconies, etc. (usually 2-3 times), and conduct a closed water test.

Soundproofing treatment:

Laying soundproof materials (such as soundproof cotton and soundproof boards) on walls and floors to reduce noise transmission (commonly seen in spaces facing the street or requiring a quiet environment).

8、 Other hard installation details

Package riser:

Wrap the bathroom and kitchen drainage pipes with tiles or boards to beautify the space.

Yin Yang corner treatment:

Use corner protectors or putty to level the internal and external corners, ensuring that the lines are vertical and flat.

Air conditioning/exhaust hole reservation:

Drill holes and install pre embedded fittings for air conditioning ducts and exhaust fan ducts.

The difference between hard and soft furnishings

Hard decoration: It belongs to the “immovable” decoration parts, such as walls, water and electricity, tiles, ceilings, etc., which are the basic framework of decoration.

Soft decoration: refers to movable and replaceable decorative items, such as furniture, curtains, lighting fixtures, decorations, etc., used to enhance spatial style and comfort.

Summary: Hard decoration is a necessary condition for “living in”, which determines the functionality, practicality, and basic aesthetics of the house, while soft decoration is an extension of the style based on this foundation. During decoration, priority should be given to ensuring the quality of hard furnishings (especially concealed works such as water, electricity, waterproofing, etc.) to avoid rework in the later stage.
