Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Adhesives and sealants rose 5.5% over the last 12 months, but all of its main inputs rose faster: plastic resins and materials +6.5%. That cost pressure may still pass through to prices.

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Adhesives and Sealants (BLS series WPU067904), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
A single blended series covering both adhesives and sealants, common in a construction materials composite where sealant cost is real but too small a line to negotiate its own index.
Price escalation in a construction contract is a clause that adjusts the contract price for movements in the published price of a named material, fuel, or labor cost after the bid. It shifts material-price risk from the contractor to the owner, within a defined base period, formula, and cap.
Escalake tracks US PPI — Adhesives and Sealants, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
