THE SHORT ANSWER
Estimate a garage floor coating from slab area, preparation needs and selected system. Keep crack treatment and moisture concerns separate from coating application so the finish promise is properly bounded.
This Australian walkthrough uses a fictional 37.16 m² garage slab coating in Adelaide, South Australia. The matching garage floor coating estimate example shows the same item quantities and amounts in an app-exported PDF. Measure your own site and replace the example rates before issuing a client quote.
1. Measure the slab to coat
Record the garage floor footprint and any excluded utility pads or steps. Use 37.16 m² for this example rather than property or garage exterior area.
For this example, the agreed starting scope is: Prepare and coat 37.16 m² of accessible garage concrete with a selected coating system. Include surface assessment, cleaning, mechanical preparation allowance, limited cosmetic surface crack treatment, coating materials, application and cleanup. No moisture mitigation or structural slab repair. A change to a listed surface, product or access assumption should trigger a revised line or allowance.
2. Assess concrete condition
Existing coatings, oil staining, cracking and moisture can change preparation. The limited crack-treatment allowance covers cosmetic surface preparation only; movement, structural cracks and slab repair require a separate assessment.
3. Specify the coating system
Product components, finish and application requirements should follow the selected manufacturer information. The A$1,190.00 material line is fictional, not a coverage benchmark.
4. Define access and curing
Agree when the garage will be cleared and when vehicles may return under the selected system requirements. Include cleanup and customer handoff.
Worked garage floor coating calculation
Two checkable lines from the example are 37.16 m² × A$8.25 = A$306.57; 37.16 m² × A$33.25 = A$1,235.57. The full 7-line estimate totals A$4,717.49 with the demonstration tax input at 0%. The amount is a fictional scenario, not an Australian market rate or a recommended selling price.
Material purchasing and installed quantities may differ. For your own estimate, use the actual takeoff, supplier prices, labour plan, access and disposal requirements. Decide how overhead, profit and the applicable tax treatment affect your final quote; do not copy the example's zero tax setting.
Before you share the estimate
- Measure coating area.
- Inspect moisture and existing coatings.
- Select system and finish.
- Agree clearing and return-to-use assumptions.
Scope boundary in this example: No moisture mitigation, slab levelling, structural crack or other slab repair, old-coating removal beyond stated preparation or vehicle-storage service.
Confirm the client details and location, item descriptions, measured units, total and validity date. If opening up the work reveals a different condition, document the changed scope and price before proceeding.
Common questions about garage floor coating
Can coating price be based only on floor area?
Area is one quantity. Surface condition and preparation can change the work substantially.
Are cracks included?
Only the defined limited allowance is included here. Measure and price larger repairs separately.
