Many people believe that applying a water-in-sand coating simply means spraying colored granules and then applying a clear topcoat. In reality, a water-in-sand facade system is a complete engineering system. Most problems such as cracking, peeling, fading, poor stone-like appearance, and coating failure are not caused by the materials themselves, but by shortcuts taken during construction. A qualified water-in-sand project requires strict execution of every procedure, from substrate preparation to final curing. Missing even one step can significantly reduce the service life of the exterior wall. Today, we'll break down the complete water-in-sand construction process and explain which steps are most commonly skipped. Part 1: Pre-Construction Preparation — Details Determine Success 1. Substrate Preparation: The Foundation of Exterior Wall Quality Substrate preparation is the most critical step in the entire coating system and also the one most frequently neglected.
