Waterproof Wall Putty Additives Supplier

The waterproof wall putty requires high standards for construction performance and water resistance in practical applications. Its final performance is usually determined by the collaborative design of functional additives in the formula.

Celotech offers key additives for the waterproof wall putty system, including RDP and water repellent agent, which are used to optimize adhesion, and water resistance stability.

Applications:

  • Water-resistant interior wall putty
  • Waterproof exterior wall putty
  • Walls in damp environments
  • Basements and semi-subterranean structures

How Waterproof Wall Putty Additives Work?

Celotech waterproof wall putty additives don’t just resist water; it protects your wall system from the inside out.

  • No more hidden structural damage:  Addditives keep rain and moisture from slowly attacking the substrate by sharply reducing capillary water absorption.

  • Stays firmly in place: Even under long-term damp conditions, our additives maintains strong adhesion, helping to prevent peeling, hollowing and detachment to wall putty.

  • Cleaner, fresher-looking walls: Its hydrophobic design helps reduce chalking and blistering, so facades stay smooth and presentable for longer.

  • Reliable strength in wet environments:Additives keeps wall putty strength, making it ideal for exposed and high-humidity projects.

Celotech Waterproof Wall Putty Solution

Redispersible Polymer Powder

Through film formation, it strengthens the internal structure of the putty, improves adhesion and flexibility, and reduces the migration pathways for moisture within the system.

Recommended Dosage: 8.0 – 50.0 kg/t

Recommended Grades: Vinabond® N511, Vinabond® N515

Water repellent agent-Aquago

By lowering the surface energy of the material, it creates a hydrophobic structure on the pore walls, thereby reducing water absorption and retarding moisture penetration.

Recommended Dosage:

Standard Waterproof Putty: 0.2% – 1.0%

Systems with High Waterproofing Requirements: 0.5% – 1.5%

Advantages of Celotech Solutions

Enhance Overall Water Stability

RDP forms a continuous polymer structure inside the putty through film-forming, thereby strengthening the system's cohesion and hydrolysis resistance; the water repellent agent reduces the surface energy of the pore walls, thereby reducing the entry pathways for moisture.

Improving Construction Performance and Operability

Improving Construction Operability

RDP can enhance the lubricity and spreading ability of wall putty, making the scraping process smoother and more uniform, while reducing the risk of shrinkage and cracking, and improving the on-site construction tolerance.

Enhance Bonding Strength and Adaptability to the Base Layer

Enhance Bonding Strength to the Base Layer

The polymer film-forming structure can significantly enhance the bonding strength between the putty and the base layer, thereby improving the overall adhesion stability of the system.

Reduce Water Absorption Rate and the Risk Of Moisture Damage

Reduce Water Absorption Rate and Risk Of Moisture Damage

The hydrophobic agent effectively reduces the capillary water absorption rate by improving the wetting properties of the material surface, thereby minimizing problems such as powdering, blistering and peeling caused by water intrusion.

More FAQS About Waterproof Wall Putty Additives

Many systems use both. RDP enhances the structure and adhesion properties, while the hydrophobic agent reduces water absorption. The two have different action directions.

Common tests include the immersion test, water absorption rate test, bond strength test, and dry-wet cycle test. The requirements of different standards may vary.

Cracking is usually associated with insufficient flexibility, deformation of the base layer, and excessive shrinkage rate in the formulation. Polymer systems can improve the crack resistance to some extent.

There will be some impact. The polymer system is usually capable of improving the construction lubricity and appropriately extending the construction time, which is beneficial for large-scale scraping operations.

No. Water resistance mainly refers to reducing water absorption and structural damage. However, the anti-mildew property also involves antibacterial properties and surface environmental control. These two aspects belong to different directions.
