Project Background & Client Requirements

Positioned as a mid-to-high-end business resort hotel in the Qianhai area, Shengjing International Hotel had been in operation for 8 years. The original laminate flooring in guest rooms suffered from widespread common problems: bulging and deformation at bathroom entrances due to long-term moisture exposure, large areas of irreversible scratches caused by luggage and furniture dragging, and obvious noise from walking and chair wheel friction. These issues not only degraded guest experience but also increased maintenance and replacement costs for the engineering department.

Given the hotel's guest structure – business travelers as the majority and family guests as the supplement – the client put forward four core requirements:

1. Thoroughly solve the pain points of water resistance and wear resistance, adapting to the high-turnover and high-frequency cleaning scenarios of guest rooms.

2. Deliver outstanding sound insulation effect to ensure quietness for business guests' sleep and work.

3. Be environmentally friendly with no peculiar smell, so that the rooms can be put into operation quickly after renovation.

4. Allow phased construction without interrupting the hotel's normal operation throughout the process.

Application Scenarios

The SPC flooring system covers all guest room spaces of the hotel, with customized solutions adapted to different room types and functional zones:

1. Standard Business Guest Rooms (King / Twin Rooms)

A total of 268 rooms with a paving area of about 5,800 m², uniformly adopting Light Cloud Oak color. The light-toned wood grain highly matches the hotel's modern and simple guest room furniture style, creating a bright and tidy resting atmosphere. The fully waterproof substrate completely solves the problems of water seepage and moisture at bathroom transition areas and around tea bars, and daily cleaning can be done directly with wet mopping, greatly improving cleaning efficiency.

2. Executive Suites & Business Suites

A total of 40 suites with a paving area of about 1,100 m², selected in Dark Brown Walnut color. The deep wood grain enhances the spatial texture and business style, fully covering bedroom areas, independent office areas and living areas. The 1.0mm sound-absorbing underlayment effectively absorbs impact noise from walking and office chair dragging, reduces sound reflection inside the room, and meets the quiet needs of business guests for office work and guest reception.

3. Family-Themed Guest Rooms

A total of 20 rooms with a paving area of about 400 m², matched with warm light wood grain style. The anti-slip texture on the floor surface and the flexible underlayment balance the safety of children running around and the comfort of foot feel. The waterproof and stain-resistant features can easily handle frequent stain scenarios such as snack crumbs and beverage spills, reducing the difficulty of cleaning and maintenance in family guest rooms.

Solution Highlights & Technical Advantages

1. Fully waterproof, ideal for commercial scenarios

The SPC substrate is formed by high-temperature pressing of natural stone powder and medical-grade resin. It is completely non-absorbent and non-expansive, fundamentally solving the common problems of traditional wood flooring such as moisture-induced bulging, mildew and deformation, making it especially suitable for water-prone areas such as hotel bathroom peripherals and tea areas.

2. Sound insulation and noise reduction for enhanced stay experience

The IXPE high-resilience sound-absorbing underlayment compounded on the back of the floor can effectively absorb walking impact and object friction noise, weaken sound transmission between floors and inside rooms. Measured walking noise is reduced by more than 18dB compared with the original laminate flooring, significantly improving the sleep experience of high-end hotels.

3. Zero formaldehyde, enabling fast project delivery

The product is produced with a formaldehyde-free formula, and the whole installation process adopts glue-free click splicing. There is no pungent odor after renovation, realizing "install on the same day, check in on the same day", which greatly shortens the room vacancy cycle of hotel renovation.

4. High wear resistance reduces long-term costs

The 0.3mm thick transparent commercial wear layer can withstand high-frequency wear from luggage rollers and furniture dragging. Under normal commercial use, the service life can reach more than 10 years, greatly reducing the floor replacement frequency and operation & maintenance costs of the hotel.

Project Outcomes

The project was constructed in three batches during off-peak periods. The renovation of 200 guest rooms per batch took only 12 days, and the whole process did not affect the normal operation of the hotel.

Half a year after putting into use, the hotel operation data shows that: the floor repair rate has dropped by 92% compared with the original laminate wood flooring, and the single-room cleaning time of guest rooms has been shortened by about 30%. Among guest reviews, the proportion of positive comments related to "quiet room with no peculiar smell" and "clean floor with good texture" has increased by 27%. This project has become a representative case of lightweight upgrade of guest room flooring for business hotels in the Guangdong-Hong Kong-Macao Greater Bay Area.
