Self-Leveling Mortar Defoamer Manufacturer | Powder Antifoam for Dry-Mix
Self-leveling mortar demands a perfectly smooth, defect-free surface for flooring applications. However, air entrainment during mixing and placement often leads to bubbles, pinholes, and craters, compromising both the aesthetics and the structural integrity of the floor. Effective foam control is therefore paramount. Specialized defoamers for self-leveling mortar, particularly powder defoamers designed for dry-mix systems, are essential additives. INVINO provides advanced solutions to ensure bubble-free, high-performance self-leveling compounds.
Why Foam Control is Critical for Self-Leveling Mortar Performance?
Entrapped air and surface foam significantly impact self-leveling mortar quality:
- Surface Defects: Causes pinholes, craters, and blisters, requiring costly repairs and affecting the final appearance.
- Reduced Flow & Leveling: Foam bubbles increase viscosity and hinder the mortar’s ability to flow and level properly, resulting in uneven surfaces. (This can disrupt the outcome of a carefully planned self leveling concrete mix recipe).
- Compromised Strength & Durability: Air voids create weak points, reducing compressive strength, abrasion resistance, and long-term durability.
- Poor Bonding: Surface bubbles can interfere with the bond to the substrate or subsequent flooring layers.
Cement-based self-leveling mortar is made of cement as the main cementing material, mixed with appropriate additives and fine sand. Because the formula of dry powder mortar contains surfactant ingredients, and construction stirring, a large number of bubbles will be introduced. These bubbles vary in size, seriously affecting the strength, construction feel and appearance of the mortar. Dry powder defoaming is added during the production process of dry powder mortar. It is an internal additive that is convenient and easy to transport. Water can be added on site to disperse and eliminate air bubbles in the mortar. Obtain a mortar surface with excellent performance and beautiful appearance.
In order to better understand self-leveling mortar defoamer, let’s share a customer case below to see the application case of INVINO powder defoamer in self-leveling mortar:
Selecting the Optimal Self-Leveling Mortar Defoamer
Choosing the best defoamer for your self-leveling formulation involves:
- Compatibility: Must be highly compatible with cement (e.g., Portland cement, high alumina cement), gypsum (if applicable), fillers, redispersible powders, superplasticizers (PCEs), and other additives. Poor compatibility leads to defects. Testing is crucial.
- Impact on Mortar Properties: The cement mortar defoamer should have minimal negative impact on flowability (rheology), setting time, bleeding, segregation, and final strength development.
- Defoaming & Antifoaming Efficiency: Needs both rapid air release during mixing/pouring and sufficient persistence to prevent surface bubbles during curing. Evaluate defoaming performance.
- Stability & Handling: The powder defoamer must be stable during storage in the dry mix and disperse easily and quickly when water is added.
How Defoamers are Used in Self-Leveling Mortar Production?
Typically, the defoamer antifoaming agent is pre-blended homogenously with other dry ingredients (cement, sand, additives) at the manufacturing plant (factory). This ensures uniform distribution when the end-user adds water and mixes on site, leading to consistent foam control. Correct dosage, determined by testing, is critical.
Add water, mix, and lay into shape. The appearance is bright, no oil slick, no pinholes.
