Wall Putty

Wall Putty

Wall putty is a white cement-based material designed to create a smooth, durable, and even surface before painting. It effectively fills cracks, holes, and imperfections, ensuring better paint adhesion and a long-lasting finish. Available in different formulations—including white cement-based, acrylic, polymer-modified, and waterproof types—wall putty caters to various applications, from interior walls to high-moisture areas like bathrooms and kitchens.

At Celotech, we provide high-performance cellulose ethers (HPMC, MHEC) and redispersible polymer powders (RDP) that enhance the quality of wall putty. Our HPMC (Hydroxypropyl Methylcellulose) improves water retention, workability, and adhesion, ensuring a smoother application and extended open time. Meanwhile, our Vinabond® RDP enhances flexibility, crack resistance, and overall durability, making the putty more resistant to external stress and environmental conditions.

1. Celopro® HPMC for Wall Putty – Enhancing Water Retention & Workability 

Celopro® hydroxypropyl methyl cellulose (HPMC) is a key additive for cement-based and gypsum-based wall putty. Grades such as Celopro® MT3025 and Celopro® MT3360 improve water retention, open time, and workability, ensuring smooth and easy application. These grades also enhance adhesion strength, sag resistance, and surface finish, making them ideal for high-quality wall putty systems.

Key Benefits:

  • Excellent water retention

  • Improved workability and spreadability

  • Enhanced adhesion and crack resistance

2. Vinabond® RDP for Wall Putty – Improving Bonding Strength and Flexibility

Vinabond® redispersible polymer powders significantly boost the mechanical properties of wall putty. Grades such as Vinabond® N511, N515, and N516 are designed to improve bonding strength to various substrates such as concrete, brick, or plaster. They also provide enhanced flexibility, impact resistance, and durability, reducing the risk of cracks and delamination over time.

Key Benefits:

  • Strong adhesion to multiple substrates

  • Increased flexibility and durability

  • Improved cohesion and surface integrity

3. Prestar® Pregelatinized Starch – Supporting Interior Adhesion

Prestar® pregelatinized starch is used to increase the initial tack and adhesion strength of interior wall putty. With recommended grades such as Prestar® 1027 and Prestar® 1105, this starch derivative improves cohesion, enhances rheology, and supports a more uniform application during mixing and troweling.

Key Benefits:

  • Boosts initial adhesion for interior putty

  • Enhances mixing stability

  • Improves surface smoothness

4. Stargel® Starch Ether – Rheology Modification and Anti-Slip Effect

Stargel® starch ether is a functional additive that plays a critical role in adjusting the rheological properties of wall putty and mortar systems. The recommended grade Stargel® ST300 helps to improve the anti-slip performance, thixotropy, and overall workability of the formulation. It ensures better handling and easier application on vertical surfaces without sagging.

Key Benefits:

  • Enhances anti-slip properties on vertical surfaces

  • Improves rheology and application consistency

  • Supports better control during troweling and smoothing

Neutral putty has become a preferred material for interior wall finishing, thanks to its smooth texture, strong adhesion, and environmentally friendly composition.

Frequently Asked Questions

The water retention rate is relatively low. After the putty is scraped, it loses water quickly and the slurry cannot be fully hydrated, which affects the overall strength in the later stage, leading to powder removal, layering, cracking, etc. During the putty scraping process, the low water retention rate can cause rapid water loss during construction, resulting in dry scraping and affecting the construction.

Always a pre-production sample for customer’s checking before mass production; Always final Inspection before shipment.
