The documents behind a good specification

A complete flooring specification identifies the product and the system around it. Begin with the exact brand, collection, product code, dimensions and construction. Add the intended application, installation instructions, care requirements and warranty terms.

Keep the version or date of the documents used for the project. If a supplier proposes an accessory, adhesive or preparation method that differs from the published guidance, ask how that proposal is supported before agreeing to it.

An attractive brochure is useful for design, but it does not replace this document set.

Assess the subfloor before covering it

Ask how the installer will assess the existing substrate and record any work required. Flatness, moisture, loose areas, surface contamination and old adhesive may influence the proposed installation system.

Request the assessment method and acceptance criteria for the actual product and adhesive. Do not adopt one moisture limit or flatness tolerance for every material. If there is a leak history or unresolved damp area, identify the cause rather than assuming a new covering will solve it.

Keep preparation as a separate quotation item so you can see what is included, provisional or excluded. Ask who approves the substrate before installation begins.

Treat installation as a system

The visible material, substrate, adhesive or underlay, fixings, joints and transitions have to work together. Confirm which method is approved for the selected product and how the installer will handle doorways, edges and adjoining floor levels.

Quick-Step’s laminate guidance addresses substrate preparation and underlay selection. Interface provides carpet tile instructions by backing type. These examples reinforce the need for product-specific guidance, rather than one generic installation recipe.

• Name the product and approved installation method.
• Identify preparation, adhesive, underlay and accessory requirements.
• Confirm movement and transition details from the relevant instructions.
• Plan access, working conditions and when the floor can be used.

For the practical differences, see Click-lock vs glue-down.

Read performance claims in context

A result for one product or assembly should not be transferred to a whole brand or material family. Keep the evidence with the specification and clarify any conditions with the project professional.

Plan maintenance and handover

Before completion, obtain the cleaning guide, written warranty and a record of the installed product. Confirm spare materials, repair access and who to contact if an issue appears.

For wood, the National Wood Flooring Association explains that changing moisture content can cause swelling or shrinkage. That makes the ongoing environment relevant as well as the installation day. Follow the selected manufacturer’s conditions rather than applying a generic humidity range to all wood products.

• Record the installed product, finish and accessories.
• Retain relevant assessment and installation records.
• Confirm cleaning methods and any excluded treatments.
• Separate product warranty from workmanship arrangements.
• Photograph agreed completion details and keep spare-stock information.
