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.
Use this fictional 37.2 sq m garage slab coating in Edinburgh to plan the estimate. The agreed work is: Prepare and coat 37.2 sq m 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 clean-up. No moisture mitigation or structural slab repair. The matching garage floor coating example and PDF shows the same inputs. These quantities and rates are teaching examples; use your own site measurements, product selections, supplier information and labour figures for a customer job.
1. Measure the slab to coat
Record the garage floor footprint and any excluded utility pads or steps. Use 37.2 sq m for this example rather than property or garage exterior area.
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.
4. Define access and curing
Agree when the garage will be cleared and when vehicles may return under the selected system requirements. Include clean-up and customer handoff.
Calculate the measured lines
The PDF uses 7 separate items. For example, Cleaning and protection is 37.2 sq m × £4.70 = £174.84; Mechanical preparation allowance is 37.2 sq m × £18.90 = £703.08. Check that each unit describes the work being priced: area for a surface, metres for a run, and a count or defined lump sum for a discrete task. A material purchase allowance can differ from the installed quantity when product sizes, cuts or layout require it.
Adding the 7 rounded line amounts gives £2,692.00. The example PDF uses a 0% tax input and no markup; those settings do not determine how to price or treat an actual job. Do not copy the rates as a local price guide.
Check the scope before sending
- Measure coating area.
- Inspect moisture and existing coatings.
- Select system and finish.
- Agree clearing and return-to-use assumptions.
Outside the base scope: No moisture mitigation, slab levelling, structural crack or other slab repair, old-coating removal beyond stated preparation or vehicle-storage service.
Confirm the site address, selected products, access, quantities, customer details and validity date. If opening the work reveals a different condition, record the change and update the relevant line before asking the customer to approve the revised work. Preview every page of the PDF so the written scope, line amounts and total tell the same story.
Common questions
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.
