The purpose is not to declare one brand universally “best”. It is to compare products only where the exact manufacturer sources support comparable fields.
| Comparison field | Why it matters |
|---|---|
| Exact product / variant | Prevents comparing different product tiers or old/current variants. |
| Surface / use | Ensures the products are intended for a comparable substrate and job. |
| Finish / appearance | Useful when appearance is part of the customer's requirement. |
| Key performance claims | Compare only source-backed benefits such as washability, stain resistance, weather protection or waterproofing function. |
| Coverage / dilution | Compare only from the exact current technical source; do not normalize assumptions. |
| Warranty | Use the exact current warranty terms, not a generic brand claim. |
| Application system | Primer, putty, number of coats and preparation can materially affect the result. |
| Current Islamia price/stock | Must be confirmed separately and should never be inferred from manufacturer websites. |
