What you need to know
- Area × thickness × product consumption gives the base quantity.
- Add waste and round up to full bags.
- Different mortars have different yields and working limits.
Use your own measurements
BricoDato tools help turn the guide into quantities, kWh, cost or a project plan.
Use the technical data sheet
Tile adhesive, repair mortar and screed products can have very different kg/m² consumption. Enter the value for the product you intend to use.
Thickness changes the quantity quickly
If the application thickness doubles, material use is close to doubling. On uneven substrates, measure several points before choosing an average.
Round up to complete bags
Buying the exact mathematical quantity is rarely possible. Use full bag sizes and leave a small reserve rather than running short mid-job.
Respect mixing instructions
Water ratio, mixing time, pot life, open time and application temperature can all affect performance.
Final check
Before buying material or doing the work, review the assumptions and technical limits that matter for your specific product, room or installation.
- Use product-specific consumption.
- Measure realistic average thickness.
- Round up to full bags.
- Respect water ratio and working time.
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.
