In construction projects, wall coatings and plastering systems affect not only appearance, but also durability, waterproofing performance, and long-term maintenance costs. Many projects experience problems such as: Exterior wall cracking and peeling Efflorescence and chalking Damp stains in bathrooms Uneven corners and edges Cracks between walls and ceilings Although these seem like surface defects, most are actually caused by substrate treatment, material selection, and improper construction practices. 1. Exterior Wall Paint Cracking & Peeling Main Causes Plaster applied too thick without layered application Dust remaining on substrate before coating No mesh reinforcement at different substrate joints Poor quality exterior putty Painting before walls are fully dry Prevention Solutions Apply plaster in layers with proper curing Remove all sanding dust before painting Use mesh reinforcement at wall junctions Select weather-resistant exterior putty Avoid construction under rain ...
Preventing tile hollowing and tile fall-off starts with choosing the right adhesive. As low-absorption porcelain tiles, slab tiles, and large-format tiles become more common, traditional cement mortar is no longer enough for modern installation requirements. In many cases, tile debonding problems are not caused only by poor workmanship — but by using the wrong tile adhesive. Different tiles require different adhesive performance levels: ✔ High water-absorption tiles Standard C1 tile adhesive is usually sufficient. ✔ Low-absorption porcelain tiles C2 enhanced tile adhesive is strongly recommended for higher bonding strength. ✔ Slab tiles & large-format tiles High-performance C2TES1 adhesives are recommended for better slip resistance, open time, and flexibility. Installation conditions also matter: • Underfloor heating → Flexible S1/S2 adhesives required • Hot & dry climates → Stable water retention and open time are critical • Large tiles on walls → Anti-slip performance (...
