How to Prevent Dripping of Painting and Plastering?

In the process of construction and decoration, the use of splattering and paint is an indispensable step. However, a common problem encountered during construction is the phenomenon of dripping, which not only affects aesthetics but may also reduce the effectiveness and durability of the materials.

 

1. Why Does Dripping Occur?

Dripping mainly occurs due to excessive fluidity of paint or splatter, resulting in sliding on vertical or inclined surfaces under the influence of gravity. This situation often arises when the viscosity of the material is low, and the internal structural support is insufficient to resist gravity. Dripping not only affects the appearance but may also lead to uneven coating thickness, thereby affecting its performance.
 

 

2. Recommendation to Add Talc Powder

Using talc powder is a common method to prevent dripping of paint or plaster. As a natural mineral, talc powder possesses excellent thickening and leveling properties. Its lamellar or platy microstructure can effectively absorb liquid from paint or plaster, helping to regulate its flow. Additionally, the good adsorption and dispersibility between talc powder particles can form a three-dimensional network structure in the material, which not only enhances internal cohesion but also improves resistance to flow. This structure effectively impedes particle movement, reducing material flow and dripping on vertical surfaces.

By adding an appropriate amount of talc powder, the viscosity of paint or plaster can be effectively increased, making it easier to adhere to vertical surfaces while reducing flow, effectively preventing dripping.

 

2.1. Why Choose Talc Powder? 

Enhances Viscosity and Consistency
Talc powder can increase the viscosity and consistency of the mixture, improving its resistance to gravity and effectively reducing dripping.

Improves Rheological Properties
By adjusting the amount of talc powder added, the flow properties of splattering and paint can be precisely controlled, making it easy to apply while preventing dripping.

Enhances Stability
Talc powder can form a stable suspension system in splattering and paint, reducing component separation and improving overall stability and uniformity.

 

2.2. The Importance of Talc Powder for Splattering and Paint 

Talc powder is not just a filler; it plays an important role in improving material performance, enhancing construction effects, and prolonging service life. By adjusting the particle size and dosage of talc powder, ideal viscosity and rheological characteristics can be obtained, thereby optimizing the construction effects of painting and splattering.
