How to use this topic hub
Measure the real project first, choose the resource closest to the work you are planning, then replace generic assumptions with exact product coverage, yield, package size or spacing guidance from the supplier. RenoMetric is designed for transparent planning rather than hidden assumptions.
Planning only: final quantities can change with site conditions, installation method, product specifications and local requirements.
