Low-Odor Interior Putty by JOSME is a dry powder wall leveling material formulated with natural mineral aggregates, inorganic minerals and high-molecular organic polymer compounds. The product features VOC content lower than 1 g/L and whiteness index over 85%, with bond strength reaching 0.5 MPa and above on concrete substrates. Packed in 18kg bags, it covers 1.2–2.5 kg per square meter under standard construction conditions. It suits construction projects that require balanced indoor air quality and flat wall surface finish.
Common wall putty contains formaldehyde, benzene and other dangerous volatile compounds, which requires a considerable period for ventilation and waiting before building occupancy. This causes delays to the overall execution of the project and impacts the safety of the interior environment.
JOSME Low-Odor Interior Putty Based on water-based polymer dispersion and high purity mineral filler formula. The small earthy smell on site after trowelling and curing is due to natural raw ingredients such as calcium carbonate, not hazardous VOCs and the odour often disappears after one hour of building.
It's a sensible choice for homeowners renovating, engineering contractors and project managers who require fast wall finishing and compliance indoor air quality.

This interior wall putty is used for surface leveling of multiple common indoor base materials, including concrete structures, cement mortar surfaces, calcium silicate boards and gypsum boards. It can be used for full-house wall construction on the premise of solid and firm substrates, unifying construction standards and simplifying on-site material management.
It also adapts to scenarios with strict indoor air quality requirements:
Healthcare facilities: Supports wall repair and renovation without pungent chemical odor, suitable for environments with precision equipment and resting patients.
Nurseries and children's rooms: Low-emission formula fits indoor environments for sensitive groups.
Occupied commercial spaces: Fast curing and low-odor features support overnight renovation and rapid site reuse.

JOSME has 5 key batch inspection techniques for all putty products to ensure stable performance in general:
Environmental Chamber Test: Confirm indoor environment compliance by detection of TVOC and formaldehyde emission levels in 3-28 days.
adherence Pull-off Test (ASTM D4541): Tests the performance of bonds under mechanical stress to assure stable adherence to base layers.
Alkali Resistance Test: No undesirable response with new high-alkali concrete substrates.
Water Resistance Test: Inspect the surface condition of the wetted specimens for softening, blistering and other flaws.
Fineness Test (Sieve Analysis) Control particle size distribution to fulfil flat finishing and topcoat matching criteria.
We store samples from each manufacturing batch so that we can guarantee consistent colour, particle size and performance characteristics for all orders.

JOSME has obtained complete system and product certifications to support global project procurement and export cooperation:
ISO 9001 Quality Management System, ISO 14001 Environmental Management System, ISO 45001 Occupational Health and Safety System, China Environmental Labelling Certification and China Green Product Certification. Complete MSDS documents are provided for export customs clearance and compliance verification.
All products comply with ISO 16000 indoor air emission standards and LEED v4 low-emission material specifications.

Standard Packaging: 18kg per bag, with reinforced packaging structure for long-distance ocean transportation and export logistics.
We support diversified customized services for B2B cooperative clients, including custom formula adjustment, private label packaging, color matching, customized particle size and sample confirmation for project verification.
Lead Time: Standard Low-odor Interior Putty: 2–3 working days Custom formula and private label orders: 7–15 working days
Q: Can this putty be used on multiple substrates in one project?
A: Yes. It is compatible with concrete, cement mortar, gypsum board and calcium silicate board substrates. Unified material application simplifies on-site inventory and construction management.
Q: Does low-odor formula reduce the bonding performance?
A: No. The product adopts synthetic resin binders to form stable cross-linking adhesion. The bond strength on concrete substrates is stably maintained above 0.5 MPa.
Q: What temperature conditions are required for construction?
A: Avoid construction under low temperature and high humidity conditions. Conventional indoor ambient conditions can meet the curing and performance requirements of the putty.
Q: How long should I wait before applying primer after putty construction?
A: Primer application can be carried out when the wall moisture content drops below 10% and pH value below 10%, which usually takes 24–48 hours after the final putty coat.
