Guides & calculators

Consumption rates, fastener and disc selection, and site checklists — practical supply information, not engineering advice.

SupplyLuck is a construction supplies distributor, not a contractor or engineer. Product information on this site describes goods, pack sizes, and logistics only — it is not technical or safety advice. Follow manufacturer TDS/SDS and applicable site regulations.

Mix consumption calculator

Area (m²) × consumption rate (kg/m²) = total dry mix required. Always add waste allowance per TDS.

Mix consumption per m² — calculator

Estimate dry mix quantity from area and kg/m² rate. Avoid under-ordering on the last square metres.

  1. Find the manufacturer consumption rate (kg/m²) on the TDS for your layer thickness.
  2. Measure net area in m² — subtract fixed obstacles or add edge allowances as your spec requires.
  3. Multiply area × kg/m², then add 5–10% waste for spillage, uneven substrate, and cut-offs.
  4. Divide by bag weight (typically 25 kg) and round up — never round down on the last room.

Which anchor for which substrate

Concrete, aerated block, timber, and steel — matching fastener type to base material.

  1. Solid concrete: expansion anchors, screw anchors, or chemical anchors rated for cracked/uncracked as per ETA.
  2. Aerated concrete / AAC block: use anchors designed for low-density masonry — standard plugs often pull out.
  3. Timber: wood screws or timber connectors; pre-drill hardwood to avoid splitting.
  4. Steel: drill with HSS or metal bit; use steel-grade anchors or self-drilling screws per load table.

Choosing a cutting disc by material

Steel, stainless, masonry, and tile — diameter, bond, and RPM basics for site work.

  1. Match disc type to material: metal (INOX if stainless), masonry/diamond for concrete and tile.
  2. Check diameter and bore fit your grinder or saw — never exceed max RPM on the disc label.
  3. Thin discs cut faster; thicker discs last longer on heavy stock.
  4. Replace glazed or chipped discs — binding causes kickback and poor cuts.

PPE checklist for the job site

Minimum protection by task — head, eye, hand, foot, and respiratory where required.

  1. Head: helmet on active sites; bump cap where required only.
  2. Eyes: safety glasses or face shield for cutting, grinding, and overhead work.
  3. Hands: cut-resistant gloves for sharp materials; chemical-resistant for wet mixes and sealants.
  4. Feet: S3 boots on site; check sole puncture rating for nail hazards.
  5. Respiratory: FFP2/FFP3 or half-mask with correct filters for dust, fibres, or solvent vapour — per SDS.

Tool care between jobs

Cleaning, storage, and consumable replacement to keep gear working on schedule.

  1. Blow out motor vents after dusty work; keep batteries on partial charge in cold storage.
  2. Clean mixers and trowels before mortar sets — hardened build-up ruins finish quality.
  3. Oil moving parts on petrol equipment per manual; drain for long idle periods.
  4. Store discs and blades dry; stack heavy tools off damp floors.

Supply checklist before starting a stage

Materials, fixings, PPE, and machinery to confirm before the crew arrives on site.

  1. Confirm dry mix brand and class match the spec — wrong binder delays the next trade.
  2. Line up fixings by substrate at each elevation; one missing anchor size stops a façade crew.
  3. Stock PPE for the whole shift plus spares — not just the first worker on site.
  4. Book pallet delivery and site access window before ordering bulk — not after the mixer arrives.
