Long-Term SPC Floor Partnership FAQ: Purchase Terms, Acceptance, and After-Sales Support

A long-term SPC floor partnership stands on three written documents rather than on a product catalogue: the purchase terms, the acceptance procedure, and the after-sales support commitment. Buyers moving from a single trial container to a repeat programme usually need five answers — which compliance documents must accompany each shipment, which site and subfloor conditions decide acceptance, which commercial terms are fixed, how samples and batches are approved, and how long production and support actually take.

This guide answers those questions in the order a procurement team meets them: compliance, capability, budget, sample, and lead time. The supply terms, installation conditions and technical limits below reflect Monalisa SPC floor documentation and the requirements that apply to click-lock, floating SPC floor systems.

Monalisa Group Co., Ltd. (SZSE: 002918) was founded in 1992 and is headquartered in Foshan, Guangdong Province. It is a high-tech listed manufacturer operating four production bases — Xiqiao (Foshan), Qingyuan (Guangdong), Tengxian (Guangxi) and Gao’an (Jiangxi) — with 37 production lines, and its portfolio includes ceramic tiles, sintered stone slabs and SPC floor.

Why Partnership Questions Appear Only After the First Order

A trial order validates appearance, packaging and handling. It does not validate repeatability. Problems usually surface in the second or third shipment, and they tend to be administrative rather than visual: whether colour and dimensional tolerance stay inside the approved reference across batches, whether the next project’s subfloor meets the same flatness and moisture limits, and who carries the cost when a joint fails because the substrate was not prepared.

SPC floor is installed as a floating floor. Planks are not glued, nailed or stapled to the subfloor. They connect to each other through a click-lock system, usually 5G, and the assembled floor moves as a single surface. That construction is what makes glue-free installation and fast handover possible — and it is also why acceptance must cover the substrate, the site climate and the perimeter gaps, not only the plank.

The SPC Floor Market Context Behind These Questions

Three publicly reported data points explain why buyers increasingly formalise SPC supply instead of ordering project by project:

• The global SPC flooring market was estimated at USD 9.8 billion in 2025 (Dataintelo, Stone Plastic Composite (SPC) Flooring Market Research Report 2034). The figure should be read with care: Grand View Research reports USD 5.9 billion for 2025 using a narrower definition of pure SPC, so the gap reflects scope rather than contradiction.
• China remains the largest exporter of plastic floor coverings under HS code 391810, reaching USD 4.97 billion in 2024 (OEC).
• Within the category, the rigid core sub-type accounted for a 74.2% revenue share in 2025 — the same rigid stone-plastic construction used in rigid stone-plastic SPC floor and high-density stone-powder core products.

Two technical references recur in acceptance discussions. Commercial-grade SPC flooring dimensional stability is required to be ≤0.10% under EN ISO 23999. GREENGUARD Gold certification, defined by UL 2818, requires testing for more than 10,000 chemicals and strict VOC limits.

Purchase Terms: What a Long-Term SPC Floor Programme Should Fix in Writing

Purchase terms are the part of the agreement that determines whether a repeat programme is workable. The Monalisa SPC flooring terms below are the items a buyer should confirm before committing volume to a single supplier.

The product family these terms apply to includes EIR SPC floor model ME26009-5, available in 1220×180 mm (48″×7″) and 1524×228 mm (60″×9″) plank sizes, in thicknesses of 4, 5, 6, 7 and 8 mm, with an EIR textured surface. The construction uses calcium carbonate (natural stone powder / limestone powder), PVC resin, a PVC calcium-zinc stabiliser and PVC lubricant.

Published performance points that buyers commonly write into the specification include: water absorption ≤0.05% on a closed-cell 100% waterproof core; zero formaldehyde and benzene content; wear resistance of 6,000–15,000 cycles with a T-grade wear rating; B1 fire rating with self-extinguishing behaviour; shrinkage ≤1‰ for dimensional stability and anti-deformation behaviour; sound reduction up to 18 dB+ with the built-in IXPE acoustic pad; and a friction coefficient ≥0.6 for slip resistance.

Acceptance: The Site Conditions That Decide Whether a Warranty Claim Is Upheld

Acceptance in SPC flooring happens twice. Factory acceptance is the pre-shipment inspection of appearance, dimensions and dimensional tolerances, mass per unit area deviation, residual indentation and peel strength for every batch. Site acceptance covers the substrate and the climate, and it is the stage where most disputes originate.

A few details in that list are worth restating because they are frequently misread. A waterproof SPC floor is not a vapour barrier. Waterproof SPC floor protects against spills, standing water and routine cleaning, but prolonged moisture from below can still cause mould, which is why a 6-mil polyethylene barrier is recommended for ground-floor concrete slabs. The subfloor must also be self-supporting — concrete, screed, fibreboard, natural stone, or ceramic or porcelain tiles. When installing over tiles, grout joints must be no wider than 5 mm and no deeper than 2 mm, with height differences between adjacent tiles of no more than 1 mm. Where cabinets are installed on top of the floor, that area must be fully glued down to the subfloor. Prolonged direct sunlight should be controlled with drapes to limit discolouration and excessive thermal expansion.

Step-by-Step: Setting Up and Handing Over a Long-Term SPC Programme

The sequence below moves a partnership from specification to warranty registration without leaving acceptance criteria undefined.

1. Define the required specification and performance class

Lock plank size, thickness (4–8 mm), wear resistance (6,000–15,000 cycles, T-grade), fire behaviour (B1, self-extinguishing), slip resistance (friction coefficient ≥0.6), acoustic expectation (IXPE pad, up to 18 dB+) and dimensional stability (shrinkage ≤1‰). Commercial-grade dimensional stability is referenced to ≤0.10% under EN ISO 23999.

2. Confirm the compliance file

Agree which documents travel with each shipment: Class A radioactivity documentation for the China market, and CE, GREENGUARD or LEED documentation where the destination market requires it. GREENGUARD Gold is defined by UL 2818 and requires testing for more than 10,000 chemicals. Monalisa Group holds 15 certifications including ISO 9001 and ISO 14001, and has been recognised as a national Green Factory.

3. Fix the commercial terms

MOQ of 500 sqm per colour, a 30-day lead time, monthly capacity of 1,000 containers, OEM/ODM customisation of size, colour and logo, and the warranty structure of 10–25 years residential or 5–10 years commercial against manufacturing defects.

4. Approve the sample and colour reference

The approved sample becomes the acceptance baseline for surface texture, colour and edge profile in every later batch. Keep it on file with the order reference.

5. Authorise production and pre-shipment inspection

Every SPC flooring batch is inspected before it leaves the factory for appearance, overall dimensions and dimensional tolerances, mass per unit area deviation, residual indentation and peel strength.

6. Verify site readiness before delivery

Measure flatness (2 mm over 2 m), check subfloor moisture with a meter (≤2%, or ≤1.5% for underfloor heating), and log installation temperature (18–30°C) and relative humidity (≤65%). Acclimate the planks in their original packaging on site for 24–48 hours.

7. Install, hand over and register the warranty

Install as a floating floor with click-lock connection, maintain 5–12 mm expansion gaps using spacers, cover the perimeter with skirting or quarter-round mouldings, and file the proof of purchase, inspection records and installation report so that any later claim can be assessed on site or remotely.

Use Cases: Matching the Application to the Acceptance Focus

The same plank is accepted differently depending on where it is installed. The table below maps common project types to the acceptance items that matter most.

SPC floor is frequently chosen for wet areas where traditional hardwood or laminate would fail. Where a project requires specific antibacterial or antimicrobial performance, the requirement should be defined at tender stage and the verification method agreed in writing, since documentation expectations differ between healthcare, education and food-related facilities.

Frequently Asked Questions

Next Step

The questions in this FAQ are answered by documents rather than by assurances: a written purchase term, a batch inspection record, a site condition log, and a warranty statement that defines its own conditions. Buyers who settle those four items before the first repeat order rarely need to revisit them afterwards.
