What you need to know
- Use class and AC rating are only part of the specification.
- Water resistance depends on the complete board and joint system.
- Subfloor flatness and moisture can decide whether the installation succeeds.
Use your own measurements
BricoDato tools help turn the guide into quantities, kWh, cost or a project plan.
Wear and use class
Choose a product intended for the expected traffic. Do not pay for a higher label if the rest of the specification is weaker for your room.
Water and joints
Check whether the product is designed for the moisture exposure you expect and follow sealing or perimeter instructions where specified.
Subfloor and underlay
The base must meet flatness, stability and moisture requirements. Underlay cannot correct a seriously uneven floor.
Look at the complete system
Board thickness, click joint, underlay, acoustic performance, trims and warranty conditions all affect the final result.
Final check
Before buying material or doing the work, review the assumptions and technical limits that matter for your specific product, room or installation.
- Confirm use class and wear rating.
- Read water-resistance conditions.
- Measure subfloor flatness and moisture.
- Include underlay, trims and waste in the budget.
Keep a small job sheet
Record the measurements, product reference, technical values you used, date and final result. For maintenance or diagnostics, also note the conditions at the time. A short written record makes future comparisons much more reliable.
Turn the guide into a decision
Use your measurements and the manufacturer’s technical data. If the decision affects fixed electrical work, structure, hidden leaks, refrigerant systems or another safety-critical installation, consult a qualified professional.
