Yongjia Tangtou court (2021) — 5 yrs, good condition with regular care

Quick answer: Modular flooring maintenance costs far less than silicon-PU/acrylic, but neglect still causes problems. Core tasks: 1) monthly seam-sand cleaning; 2) quarterly lock check; 3) annual expansion-gap review; 4) single-tile replacement; 5) line upkeep. Annual maintenance ≈ 1-2% of initial cost. Proper care extends the 8-year warranty to 10-15 years of real use.

FAQ

High-pressure washer OK?

Yes under 60 bar, 30cm+ away, avoid blasting seams directly. Annual deep clean is enough.

Winter snow removal?

Plastic shovel or soft broom; avoid industrial salt (use calcium-based de-icer).

Line repaint?

Color-tile lines need none; painted lines re-coat every 2-3 yrs.

Leave a cracked tile?

Replace within a week — damage spreads to neighboring locks.

Usable past 8-yr warranty?

With proper care, 10-15 yrs real life. Get an evaluation near warranty end.
