Quota application for tile-and-stone grout sealing on floors: the tiling items' work content ends at joint wiping and pointing, excluding grout sealing - it needs its own item; the grout item is chosen in three steps: dedicated item first, then a tile-finish table item carrying sealant consumption, else a supplementary quota or market rate build-up

Topic Positioning

After tile and stone floors are laid: does grout sealing (two-component sealants, epoxy coloured sand) need its own quota item, how the grout item is chosen and priced, and the red lines of double counting and over-application.

Core Conclusions

1. Tiling items' work content excludes grout sealing.

• Beijing DB11/T 2382-2024, Annex A building and decoration works, A.11.2 tile finishes: A-11-44 "stone floor, piece area within 0.36 m2", A-11-53 "tiles, piece area within 1 m2", unit m2, work content "cleaning the substrate, setting the finish, wiping the joints etc." - ending at wiping, no sealant.
• Railway TB/T 10831-2024 Volume 10, floor works, "4. tile finishes": FY-1214 to FY-1217 ceramic floor tiles (banded by piece area 0.1 / 0.36 / 0.64 / over 0.64 m2), work content "clean the substrate, trial-lay and snap lines, soak, saw and trim, spread the bed, lay the finish, point the joints, clean the face." Separate items follow: FY-1235 "tile floor pointing" (10 m2), FY-1236 "tile floor silicone" (10 m), FY-1237 "tile floor brass divider strips" (10 m) - no sealant item.
• Conclusion: tiling items end at wiping / pointing (cement or jointing compound); two-component sealants and epoxy coloured sand are separate workings needing separate items, or enter the all-in rate through the bill item description.

2. Choosing the grout item - three steps by priority

1. The region has a dedicated "grout sealing" item -> apply it. Hunan 2024 consumption standard (2025 edition in the source data) A11-200 "tile grout sealing", under "other works", whose section work content includes "3. tile grout sealing".
2. No dedicated item, but the tile-finish table holds one with sealant consumption -> apply that. Beijing DB11/T 2382-2024 A-11-67, unit m2, consumption: labour - all-in Grade I 0.0240 workday; materials - two-component sealant, 400 ml cartridge, 0.1040 set; other materials 1.5%; plant - other plant 2%. Caution: in the ledger consulted this item is named "floor divider strip, monolithic finish insert", mismatching its consumption (sealant only, no strip material, per m2) - suspected mis-entry of name or data; verify the item name and unit against the original quota volume or the pricing software before use.
3. Neither -> compile a supplementary quota, or build up from market labour + materials: labour + sealant (about 0.1 set/m2, 400 ml per set) + other materials 1.5% + plant 2%, confirmed by the quota authority / employer.

3. Measurement

Same basis as the tile finish - net laid area in m2 with the same deduction rules; if measured per joint length in m, convert by tile size (800 x 800 tiles at 2 mm joints are about 2.5 m per m2).

4. Red lines and traps

1. No double counting: tiling items already contain wiping / pointing - no extra pointing item; in the railway quota "pointed" and "unpointed" are alternatives - only "unpointed" tiles may add FY-1235 pointing.
2. No over-application: grout sealing is an upgraded fill material - it is neither "movement-joint caulking" (Beijing A-9-269, insulation backer rod plus sealant, a roof / waterproof movement-joint process) nor curtain-wall silicone.
3. Bill item descriptions: where the tender BOQ omits grout sealing but the design requires it, it is a new item through variation or added description - never slipped into the original all-in rate. Under the bill basis, the fill material of the tile-floor item is locked by the item description "pointing material type" and priced into the all-in rate (GB/T 50854-2024 Annex L, tile floors).

Applicability Boundaries

• The tests come from Beijing DB11/T 2382-2024, railway TB/T 10831-2024 Volume 10, the Hunan 2024 standard (2025 edition in the source data) and GB/T 50854-2024; other regions and sectors (Tianjin etc.) must first check their current decoration pricing basis for a grout item - borrowing another region's quota requires the basis and conversion stated in the compiling notes.
• Units follow the item (Beijing A-11-67 in m2; railway pointing 10 m2, silicone 10 m, brass strips 10 m) - check before applying to avoid quantity mismatch.
• Once consumption is set, price differences between quota base period and compiling period adjust per the contract / compiling rules; this card gives the route, not the project's rates and charges.
• Ledger mismatches between item names and consumption resolve against the original quota volume.
