 Importance of Plaster Mortar Curing Curing plaster mortar is crucial in construction to ensure wall quality, bonding strength, and durability. Proper plaster mortar curing times help prevent cracks, hollowing, and improve subsequent works such as tiling or waterproofing. Construction professionals should plan curing periods based on mortar type and environmental conditions. 1️⃣ Ordinary Cement Mortar Curing Ordinary cement mortar is one of the most commonly used plaster materials. Under normal temperature (around 20℃) and humidity, it should be cured for at least 7 days. Keeping the surface moist promotes cement hydration, improves strength, and reduces the risk of cracking. Keywords: cement mortar curing, plaster mortar curing time 2️⃣ Cement-Lime Mortar Curing Cement-lime mortar combines the strength of cement with the flexibility of lime. A curing period of at least 7 days ensures full hardening and optimal bonding. Lime content is moisture-sensitive, so proper wet curing is es...

 Exterior wall paint may look like “just a layer of coating,” but in real projects, it is often one of the most failure-prone and costly materials to repair . Have you experienced these issues? ✔️ Color fading or chalking shortly after completion ✔️ Blistering, peeling, or water penetration after rain ✔️ Huge price gaps between “similar” exterior paints ✔️ Products passing sales claims but failing inspections 👉 In most cases, the problem lies not in application, but in incorrect selection and misunderstood testing standards . The core mission of exterior wall coatings is simple but demanding: to withstand complex, long-term outdoor environments . 1. Main Classification of Exterior Wall Coatings From an engineering and testing perspective, exterior coatings are commonly classified by binder type and decorative effect . 1️⃣ By Binder System (Durability-Oriented) Acrylic exterior coatings Silicone-acrylic coatings Pure acrylic or fluorocarbon systems fo...
