In mortar materials, due to the low viscosity of the slurry, air bubbles rise due to buoyancy. The liquid film of air bubbles that moves to the surface generates a pressure difference due to gravity, causing the film thickness to decrease and the air bubbles to eventually collapse. This method of…

Have you ever experienced this kind of breakdown? The exterior wall putty peels right after you apply it, the self-leveling floor cracks after just a few days, and the tiles are always hollow... It's not that the construction was done poorly, but rather that you're missing a crucial "helper"—…

In building materials like dry-mix mortar, tile adhesive, and putty, redispersible latex powder acts like an invisible glue—making the materials adhere more firmly and more flexible when exposed to water. But did you know? Its core ability, film formation, isn't simply a matter of drying in the sun…

Exterior wall cracking, tile adhesive peeling, and hollowing in waterproof mortar are often caused by latex powder not meeting specified flexibility standards. Flexibility testing is key to identifying potential problems. Here's a quick guide to the key points!Ⅰ. Why is flexibility testing…
