During high-speed mixing, pumping, and trowel application, mortar continuously entrains air. Formulations containing water reducers, cellulose ethers, and other admixtures are especially prone to forming stable foam. If foam remains in the mortar for an extended period, it can affect uniformity and the final surface appearance.
One of the key advantages of this Powder Defoamer is its fast response. Once added to the system, it quickly acts on the foam film, breaks larger bubbles, and helps release entrained air. This rapid action is particularly valuable for products such as self-leveling mortar, grouting materials, and plastering mortar where surface quality is critical.
From a production perspective, high defoaming efficiency helps the mixed mortar return to a stable state faster. During application, it helps reduce pinholes, pockmarks, and other defects caused by air bubbles accumulating at the surface. The result is not simply less foam, but a cleaner, more uniform mortar condition and easier control of the finished surface.
Key benefits:
For many mortar systems, the real challenge is not the foam immediately after mixing, but re-foaming later in the process. During transport, pumping, vibration, spreading, and trowel application, the slurry is still exposed to shear and disturbance, allowing foam that has already been removed to reappear.
A high-performance defoamer therefore needs more than instant foam removal; it also needs sustained foam-control performance. After rapidly breaking foam in the initial stage, the product continues to suppress new foam formation and helps keep foam levels stable through subsequent application steps.
This is particularly important on site. Self-leveling mortar, for example, may go through mixing, conveying, spreading, and defoaming roller treatment. If the defoamer works only during mixing, excessive foam may return during spreading, resulting in pinholes and surface defects. Long-lasting foam control extends the effective foam-control window and helps product performance better match real application conditions.
Key benefits:
Mortar is not a single material; it combines cement, sand, fillers, cellulose ethers, redispersible polymer powder, water reducers, and other components. If a defoamer significantly interferes with any one of these admixtures, it may trigger changes in flowability, segregation, bleeding, or surface quality.
Compatibility is therefore a key factor in whether a defoamer can be successfully incorporated into an industrial formulation. A highly compatible product is not simply one that can be added to everything; it should disperse well and perform effectively in common cement-based systems while minimizing interference with other functional admixtures.
For formulation engineers, this makes it easier to identify a suitable addition window during product introduction. For production teams, it helps maintain formulation stability when changing batches or dealing with raw-material variation. Compatibility becomes especially important in more complex formulations such as self-leveling mortar, tile adhesive, and grouting materials.
Key benefits:
For mortar products, foam control is only one objective. Strength, setting time, and the application window are equally important. If adding a defoamer significantly changes the setting profile or adversely affects hardened mechanical performance, reducing surface foam alone is not enough to make the product practical.
The application approach of this product is to control harmful air bubbles and improve system density at an appropriate dosage and with proper formulation matching, while minimizing disruption to the original setting process. In other words, foam control is achieved without sacrificing the basic performance of the mortar.
For customers, this translates into two practical benefits: first, the formulation’s strength design does not need to be fundamentally changed because of the defoamer; second, familiar open time, setting behavior, and downstream application procedures can remain relatively stable. For specific projects, small-scale trials are still recommended based on the cement, water reducer, sand, and environmental conditions to confirm formulation compatibility.

Powder Defoamer is a powdered foam-control material used in dry-mix mortar, cement-based materials, and gypsum-based materials. It helps reduce harmful air bubbles generated during mixing and application while improving material flowability, density, and surface quality.
Powder Defoamer is widely used in dry-mix mortar, cement-based self-leveling mortar, grouting materials, repair mortar, waterproof mortar, cement mortar, and gypsum-based materials. Different Powder Defoamer grades can be selected according to the material system and performance requirements.
Cement-based materials can generate air bubbles during mixing, while admixtures such as PCE, RDP, and HPMC may also affect foam stability. Proper use of a cement-based defoamer can reduce excessive air content, minimize pinholes and air voids, and help improve material density and surface appearance.
A common reference dosage is approximately 0.01%–0.10% of the total dry powder material. Actual dosage depends on the cement, sand, PCE, and other admixtures in the formulation. Small-scale trials and dosage-gradient testing are recommended to determine the optimum level.
Yes. Powder Defoamer can generally be used together with PCE polycarboxylate water reducers, RDP, HPMC, and other construction admixtures. In highly flowable self-leveling and grouting systems, proper matching of PCE and defoamer helps balance flowability, air content, and surface quality.
Self-leveling mortar has high requirements for flowability, surface flatness, and air-bubble control. The appropriate self-leveling mortar defoamer should be selected based on the cement system, PCE type, filler composition, and target flowability, with dosage confirmed through actual formulation testing.
Grouting materials generally require good flowability and density. Highly flowable formulations may generate significant air bubbles during mixing and grouting. A suitable grouting material defoamer helps control harmful air bubbles, improve grout density, and enhance the surface quality after hardening.
No. Defoamer dosage should be controlled within an appropriate range. Excessive addition may affect air content, flowability, and other system properties. The appropriate grade and dosage should therefore be determined through testing with the specific formulation.
