Eco-friendly Interior Putty

Eco-friendly Interior Putty for Interior Walls — High Whiteness, Low VOC, Easy Sanding

Eco-friendly Interior Putty from JOSME is a dry powder wall leveling compound formulated with inorganic minerals and organic dry powder raw materials. The product features VOC content far below 1 g/L and zero added formaldehyde, with a whiteness index exceeding 85%. It balances stable construction performance, filling effect and environmental safety. Backed by 26 years of coating production experience, this interior putty fits residential and commercial interior renovation, delivering stable bonding strength, smooth troweling experience and low dust sanding performance while meeting modern indoor air quality standards.

What Is This Interior Wall Putty?

Traditional interior fillers adopt petroleum-based raw materials and synthetic solvent formulas, which release VOC and formaldehyde during curing, affecting indoor air quality for construction workers and long-term occupants.

Eco-friendly Interior Putty optimizes the formula to solve conventional indoor environmental problems. It adopts natural mineral materials, bio-based binders and low-emission redispersible polymer powder, maintaining standard construction and filling performance while reducing harmful substance emissions for indoor wall base treatment.

Technical Specifications

Key Performance Advantages

1. Stable Bonding Strength Tested in accordance with ISO 4624 standards, the pull-off adhesion strength is over 0.5 MPa. This bonding performance reduces the occurrence of micro cracks and delamination commonly seen in ordinary wall fillers after construction.

2. Smooth On-Site Workability The formula supports labor-saving trowel operation with high construction tolerance. It adapts to large-area interior wall leveling work and lowers the rework rate during on-site construction.

3. Low Shrinkage Rate The product controls shrinkage degree during drying and curing, effectively avoiding fine hairline cracks on the wall surface and maintaining uniform flatness to create qualified base conditions for topcoat coating.

4. Easy Sanding with Minor Traces After full curing, the wall surface can be sanded with less dust. The sanded surface leaves minor traces and few defects, reducing later repair work and shortening the overall finishing construction cycle.

5. Neutral pH & Skin-Friendly Formula The neutral formula causes less irritation to workers’ skin during long-term construction, suitable for continuous operation in large-scale interior projects.

6. High Whiteness & Hiding Performance With a whiteness index above 85%, the product covers original base color and minor surface defects of walls. It reduces the consumption of finishing paint and ensures uniform color presentation of the final decorative layer.

Eco-friendly Interior Putty Applications

This interior wall putty is widely used for substrate leveling in interior decoration works, compatible with multiple common building base materials, including concrete structures, cement mortar surfaces, calcium silicate boards and gypsum boards.

In addition to conventional household interior renovation, it is also applicable to indoor spaces with strict air quality and mildew resistance requirements, such as medical facilities, educational buildings, kitchens and laundry rooms.

Quality Control Process

All batches of JOSME interior putty undergo three-stage quality inspection, including incoming raw material inspection, in-production process monitoring and finished product performance testing.

Core testing items cover particle size detection through laser diffraction and sieve analysis to ensure finished particle size below 100 microns, Vicat needle setting time test, wet and dry adhesion pull-off test compliant with ISO 4624 standard, GC-MS component analysis to exclude prohibited substances such as phthalates, APEO and heavy metals, as well as scrub resistance test to verify surface durability.

We retain samples for each production batch to stabilize product color, particle size and construction performance across all orders.

Certifications

JOSME has obtained ISO 9001, ISO 14001, ISO 45001, ISO 50001 system certifications, China Environmental Labelling Certification and China Green Product Certification, and is recognized as a national Green Factory.

FAQ

Q1: What practical benefits does easy sanding bring to interior decoration projects?

A1: The cured putty layer can be sanded with low dust and shallow traces, reducing surface defects and repair work. The flat base layer provides stable conditions for topcoat construction and ensures uniform wall finishing effect.

Q2: Is this putty suitable for whole-house interior wall leveling?

A2: Yes. It features smooth troweling and high construction tolerance. The cured wall surface is firm with stable bonding, not prone to peeling and hollowing, which fits full-house interior renovation construction.

Q3: How does the product improve the final wall decoration effect?

A3: The whiteness above 85% covers wall base color and minor flaws. Stable forming performance avoids surface unevenness, making the color of decorative topcoat more uniform and consistent.

Q4: Can this product be used for LEED and BREEAM certified projects?

A4: Zero formaldehyde and low VOC features meet the low-emission material standards of LEED and BREEAM systems. The specific credit contribution depends on project certification rules. We can provide test reports for project assessment.

Q5: Does eco-friendly formula affect moisture and mold resistance?

A5: No. The formula contains hydrophobic additives and natural mineral components, maintaining basic moisture regulation and mold resistance performance, with complete test data available for reference.

Q6: What causes pinholes during putty application and how to avoid them?

A6: Pinholes are mainly caused by porous substrates and trapped air. Priming treatment and two-coat construction can effectively avoid pinhole defects and ensure smooth wall surface.
