What you need to know
- Check flatness against the flooring manufacturer’s tolerance.
- Investigate moisture before covering the floor.
- Remove dust, loose material and unstable patches.
Use your own measurements
BricoDato tools help turn the guide into quantities, kWh, cost or a project plan.
Check flatness
Use a straightedge or suitable measuring method and compare with the flooring specification. High spots and hollows can stress click joints and make the floor move.
Check moisture
Concrete, screeds and ground floors may need specific moisture testing or vapour control. Follow the flooring and subfloor system requirements.
Make it clean and stable
Remove debris, adhesive lumps and loose areas. Repair damaged sections with compatible products and allow them to cure fully.
Do a trial before opening every box
Check door clearances, transition heights, first-row layout and edge details. Solving these issues first reduces waste and rework.
Final check
Before buying material or doing the work, review the assumptions and technical limits that matter for your specific product, room or installation.
- Check flatness against the product limit.
- Test or assess moisture correctly.
- Repair loose or unstable areas.
- Plan door clearances and transitions before installation.
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.
