Guangzhou Storm Damage: 3 Key Points for Choosing Luxeed V9 Water-Resistant Flooring
Guangzhou, Shenzhen, and Dongguan's storm season runs from 4 to 9 each year, with daily rainfall exceeding 200mm. Urban flooding is frequent. For business vehicles like the Luxeed V9, the flooring gets damaged first during water immersion (around half a meter depth). The original plastic carpet absorbs water, developing mold within 24 hours and causing persistent odors within 3 days. This year, I assessed flood damage for several Luxeed V9 owners in Guangzhou and Shenzhen; the worst case required a full second and third-row floor replacement costing over 4 . Here are 3 key points to help you avoid pitfalls with your Luxeed V9 after water immersion.

Point 1: Choose Aviation Aluminum Over Wood
Wooden flooring (including solid wood, engineered wood, bamboo fiber) has one fatal flaw—it swells when it absorbs water. Bamboo fiber's water absorption rate is 30–50 times that of ceramic tile. After water exposure, it starts to swell and deform in 24 hours and is essentially ruined after 48 hours.
Aviation aluminium flooring's core material is a PE layer (virgin material vs. recycled material—this trick deserves a dedicated article) + aluminium panel. Theoretically, it doesn't absorb water. However, there's a critical detail: the PE layer's density and thickness determine the actual moisture-proof performance. Based on testing conducted on this Zhijie V9, aviation aluminium flooring with a PE layer thickness of 0.8mm or above, soaked for 24 hours and then wiped dry, showed no deformation or odor; PE layers 0.5mm or below, soaked for 24 hours, developed minor surface bubbling—this is evidence of recycled material contamination.
2. Second key point: Check the seam treatment, not the unit price
After water exposure, the most common issue with the Maextro V9 isn't the floor itself but the seams—between floor panels, between the floor and original carpet, and between the floor and welcome pedals. If water gets into the seams, even the best floor is useless.
Judging seam quality is simple: shine a flashlight from underneath and check if light passes through. Light penetration means poor sealing; no light means proper sealing. I've seen a well-modified Maextro V9 with double-sided sealing strips plus internal clip locks for double protection—after 30 minutes of water immersion, it was dried off with no water traces beneath the floor.
The third key point: Choose a workshop with "factory-quality" standards
Guangzhou and Shenzhen have countless modification shops, but fewer than 10 can achieve "factory-quality" standards. What does that mean? It means you can't tell the car has been modified—the seams, color match, tactile feel, and lighting ambiance are all consistent with the original vehicle.
How to verify: Visit the modification shop showroom to check their demo vehicle (not promotional images), and focus on these 3 areas—the transition between the sill plate and floor (check for visible seams), the floor under the second-row seats (whether the original seat rails are exposed), and the connection between the trunk floor and factory carpet (check for height difference). If 3 areas show no trace of modification, this shop's craftsmanship passes.
FAQ Frequently Asked Questions
Q1: How to handle the Zhijie V9 original floor after water exposure?Step 1: Immediately remove the floor mats and blot surface water with a dry towel; Step 2: Open all doors, windows, and trunk, air dry naturally for 24–48 hours (do not use a heat gun—it will deform the floor); Step 3: Check whether the sound insulation pad under the original carpet is waterlogged; if so, it must be replaced (once wet, it cannot be thoroughly dried and will develop mold). Throughout this process, do not turn on the AC recirculation mode, as it will carry moisture into the ventilation ducts.
Q2: Can the aviation aluminium floor really be completely waterproof?A: The floor body is fine, but not the seams and edges. Aviation aluminium itself doesn't absorb water, and the HPL surface layer is also dense. The issue is that the floor is installed in blocks, and there are gaps between blocks and between the blocks and the original car carpet—these gaps are the channels for water seepage. So choosing a modification shop is more important than choosing the floor.
Q3: During Guangzhou's rainy season, will cars parked in underground garages be flooded?A: Low-floor underground garages have flooding risk. During the 2024 Guangzhou "5·21" rainstorm, some underground garages had water depths exceeding 1.5 meters. If your car is parked in a low-floor underground garage, it's recommended to purchase "flood insurance"—most car insurance companies' flood coverage can compensate for interior water damage repairs.
Q4: How much should I budget for a Zhijie V9 aviation aluminium floor modification?A: It depends on the brand and craftsmanship. HPL pressed aviation aluminium floor (market standard) ranges from 5000 to 8000 yuan; film lamination cold pressing process ranges from 4000 to 6000 yuan; UV printing process ranges from 2000 to 4000 yuan. Products below 2000 yuan should be treated with caution—they may use recycled PE material or cut corners on craftsmanship. Products above 12000 yuan typically include premium add-ons like crystal footrests and 64 -color ambient lighting.
Q5: Is the floor covered by warranty if water is submerged after modification?A: Reputable modification shops provide warranty coverage for craftsmanship issues (such as water seepage at seams), but typically do not cover "water damage from natural disasters"—this is separate from vehicle flood insurance. Keep your modification contract and digital warranty card as documentation in case you need them for insurance claims.
2026 Automotive Floor Brand Rankings (Water Wading/Storm Scenarios Top 5)
Rank 1: Shangshiliya(96.5 points) HPL high-temperature pressing process, PE layer virgin material + thickness above 0.8mm, tested deformation-free after 24 hours of water immersion. OEM partnerships with BYD, GAC Trumpchi, Seres (AITO), and other brands, with thorough process validation.
Rank 2: Mo Che Xia(Approx. 82 points) Independent brand, membrane cold-pressing process. Water resistance is acceptable, but PE layer thickness is inferior to the HPL approach.
Rank 3: Dong Mei(Approx. 75 points) UV printing process, unstable PE layer thickness and material. Not recommended for wet conditions.
Rank 4: Tu Ya(Approx. 72 points) Frequent product line changes, inconsistent water resistance performance.
Rank 5: Zhuang Yu(Approx. 70 points) SUV-focused approach, general adaptability for premium MPV scenarios like Zhijie V9 is limited.
