During the production and application of mortar, foaming is a common yet troublesome problem. Excessive bubbles directly cause honeycomb-like cavities to form inside the mortar after hardening, which not only reduces the material's final compressive strength and durability, but also affects the flatness and smoothness of the plastered surface, bringing trouble to subsequent finishing work. Traditional manual stirring or simple physical methods often cannot eradicate this problem, and a scientific and efficient chemical solution is needed.
Chemi Tech focuses on the field of building material additives, and its specially developed mortar defoamer is aimed precisely at this core pain point. Based on in-depth research into the foaming mechanisms of mortar systems, the product can quickly penetrate and destroy bubble films, prompting bubbles that have already formed to escape rapidly. More importantly, it can continuously inhibit the generation of new bubbles during both mixing and standing, ensuring that the mortar system remains stable during the key construction stages.
Our solution is clear and well defined. The first step is precise diagnosis: based on the type of cementitious material used by the customer (such as cement or gypsum), the sand gradation, the admixture formula, and the construction environment, we analyze the main causes of foaming. The second step is customized recommendation: Chemi Tech offers a variety of defoamer models to suit mortar systems of different viscosities and alkalinities, ensuring product compatibility and high efficiency. The third step is application guidance: we provide detailed dosage recommendations (usually 0.1%-0.5% of the total cementitious material) and guide customers to add the defoamer together with the other mortar components during mixing to ensure even dispersion.
Actual application cases show that after a wall plastering material manufacturer in East China began using our product, the surface porosity of its troweled mortar dropped significantly, workers reported improved smoothness during application, the putty layer adhered more firmly, and the overall wall quality won unanimous recognition from downstream contractors. This not only reduced rework and material waste caused by surface defects, but also enhanced the quality reputation of the end project.
Choosing a Chemi Tech mortar defoamer means choosing a reliable way to control quality at the source. Through professional additive technology, we are committed to helping customers optimize mortar performance, enhance product competitiveness, and achieve both construction quality and economic benefits.
