Foam Control Matters in the Construction Industry: The Role of Defoamers

Nov 07, 2025
Foam formation is a common challenge in cement, mortar, concrete admixtures, and other construction chemicals. Mechanical mixing, surfactants in additives, and polymer-rich formulations often trap air, leading to persistent foam. In construction, this is more than a visual problem—excessive foam can weaken concrete strength, reduce bonding performance, and cause uneven surfaces or pinholes in coatings and sealants.
In cementitious systems and polymer-modified building materials, stable foam can reduce compressive strength and durability. It may also disrupt workability, making pumping and application inconsistent. To maintain smooth flow, proper compaction, and reliable surface finish, many manufacturers introduce high-performance defoamers into their formulas.

A well-designed construction defoamer helps release entrapped air quickly, improves density, and supports uniform curing. Silicone, mineral-oil, and polyether-based defoamers are commonly used depending on system pH, viscosity, and interaction with other additives. For construction materials like plaster, putty, waterproof coatings, and repair mortars, compatibility and long-term stability are essential. An effective defoamer ensures consistent texture, reduced defects, and improved performance throughout production and application.

Rickman defoamer solutions are designed for modern construction systems. Our defoamers offer balanced foam-breaking and foam-suppression functions without affecting material flow or mechanical strength. Rickman also delivers technical evaluation, formula guidance, and tailored recommendations to help partners optimize performance in real construction environments. From product selection to after-sales support, we work closely with customers to ensure consistent quality and efficiency in every batch.
