Calculating paint coverage per square meter is essential for controlling project cost, purchase quantity and delivery planning. The required amount depends on substrate absorption, surface roughness, application method, coating thickness and number of coats. A theoretical coverage figure should therefore be used as a starting point rather than the final purchase quantity.
Caruns product specifications list a typical theoretical coverage of approximately 8 to 10 square meters per kilogram for applicable coating products under suitable application conditions. This equals roughly 0.10 to 0.125 kg of paint per square meter for the stated theoretical coverage.
| Project Area | Approximate Paint Requirement |
|---|---|
| 100 m² | 10–12.5 kg |
| 500 m² | 50–62.5 kg |
| 1,000 m² | 100–125 kg |
| 5,000 m² | 500–625 kg |
Actual consumption may increase on porous concrete, rough plaster, textured surfaces or poorly prepared walls. Application by roller, brush or spray can also influence material usage.
Before calculating a bulk order, confirm:
Total coating area
Substrate type and porosity
Interior or exterior application
Number of coating layers
Primer and topcoat requirements
Application method
Required color and finish
Expected construction losses
For large projects, we recommend calculating each layer separately rather than applying one average coverage figure to the entire coating system.
Direct manufacturer sourcing is useful when coverage, formulation and batch consistency must remain stable across multiple deliveries. A manufacturer can control raw-material ratios, viscosity, solid content and production records directly, while a trader normally relies on another production source.
Caruns manufactures architectural and industrial coating systems in its own production base and supports standard packaging of 1 kg, 5 kg and 20 kg. Standard orders can start from 50 pails, while OEM and ODM production is available for customized requirements.
Our production process covers mixing, dispersion, grinding, tinting, filtration and filling. Incoming materials are tested for solid content, viscosity, pH, fineness and environmental indicators. Finished batches are checked for hiding power, adhesion, scrub resistance, water resistance and color consistency.
Quality control follows IQC, IPQC, FQC and OQC, helping maintain repeatable performance across bulk production.
For project sourcing, purchase calculations should include coating area, theoretical coverage, coating layers, packaging size, production schedule and replenishment requirements. Export orders should also confirm MSDS, transportation documentation and destination-market compliance.
Caruns operates a 16,000 square meter manufacturing base with annual production capacity above 20,000 tons, supporting large-volume project supply and repeat orders.
Accurate paint calculation therefore starts with square meter coverage, but reliable procurement also requires substrate evaluation, coating-system planning, manufacturing consistency and realistic project consumption control.
