Efflorescence and whitening are common challenges for exterior cement‑based mortar, exterior wall putty and decorative mortar during construction and service life. Such defects result in mottled stains, surface chalking and peeling, raising project rework costs. Exterior efflorescence falls int...

Colored mortars, mala colored stone finishes, and other decorative building materials are increasingly used in exterior wall decoration and landscape engineering, valued for their rich color layers and natural texture. However, many construction teams and manufacturers have encountered the same...

Efflorescencein cement-based materials is a long-standing and widespread challenge inconstruction engineering. Whether in cement mortar, concrete, or cement putty,issues such as surface whitening, reduced adhesion, and patchy discolorationare often closely linked to alkali precipitation. Cement an...

As theGreat Heat solar term unfolds, the sun blazes at its fiercest. The soaringtemperatures test every outdoor worker—and put every building material productto a real-world trial. Amid the sweltering heat on construction sites and inthe precision of our laboratories, the Jiarun team responds...

In the engineering application of dry-mixed mortar, surface efflorescence, whitening and color difference have long been common headaches for constructors and building material manufacturers. Efflorescence not only ruins the decorative appearance, but also may cause weakened coating adhesion and...

I. Misconceptions and Truths about PVA (I) Refuting Doubt 1: Is PVA a Terrible Substance with No Use in Mortar? Verification and Clarification : This view is inaccurate. We need to look at PVA from an objective and scientific perspective. In specific scenarios such as completely...
