Use of Dolomite (300 Mesh) in Wall Putty
Dolomite powder of 300 mesh is a fine-grade mineral filler widely used in wall putty manufacturing due to its smoothness, brightness, and chemical properties.
Key Functions in Wall Putty:
Filler & Body Provider
Increases bulk and provides smooth texture.
Fills micro-pores and imperfections in the wall surface.
Improves Workability
Enhances spreading and application properties.
Makes the putty creamier and easier to apply with a trowel or blade.
Whiteness & Smooth Finish
High-quality dolomite has good brightness, contributing to the whiteness of putty.
300 mesh fineness gives a uniform, polished finish after application.
Durability & Strength
Calcium magnesium carbonate in dolomite improves hardness and scratch resistance of the dried putty film.
Alkali Resistance
Dolomite is alkaline in nature, helping wall putty resist damage from cement’s alkalinity.
Cost Efficiency
Replaces costlier fillers like higher-grade calcite, making the product economical while maintaining quality.
Typical Usage in Formulation:
Used along with calcite powder and white cement in varying ratios depending on brightness and smoothness requirements.
Common in cement-based putties for both interior and exterior applications.
