White cement-based polymeric putty or wall putty has become an essential component in modern construction, particularly in delivering superior finishes for interior and exterior walls. It is a polymer-modified, white cement-based powder applied to plastered surfaces to achieve a smooth, uniform, and durable base before painting. This product not only enhances aesthetic appeal but also strengthens paint adhesion, prevents flaking, and improves resistance against dampness and minor surface irregularities.
To ensure product quality, performance, and safety for consumers, the Bureau of Indian Standards (BIS) has mandated certification for white cement-based polymeric putty under the Indian Standard IS 17545:2021. This certification is now a regulatory requirement for manufacturers intending to sell or distribute such products in the Indian market.
The Indian Standard IS 17545:2021, titled “White Cement Based Wall Putty”, lays down the specifications for polymeric putty used as a finishing coat over cement plaster or concrete walls. It prescribes essential manufacturing, chemical, and physical properties that the product must conform to for ensuring quality and consistency.
This standard covers a comprehensive range of parameters including product composition, consistency, workability, lead content, polymer percentage, and strength attributes. These requirements are vital for establishing the putty’s effectiveness in various environmental conditions and application surfaces.
Under IS 17545:2021, white cement-based putty must exhibit specific performance traits to be certified. The standard sets out test methods and thresholds for properties such as setting time, consistency, tensile adhesion strength, and water retentivity. These ensure the putty offers adequate open time for application, superior bonding with the base surface, and resistance to peeling or cracking post-application.
Another critical parameter is polymer content, determined through loss on ignition, which is crucial for enhancing flexibility and water resistance. The degree of whiteness is also specified, as it directly impacts the visual quality and brightness of the applied surface, making it more receptive to various paint shades.
Furthermore, lead restriction is a mandatory safety requirement. The product must comply with limits on permissible lead content to ensure it poses no health hazards to users, especially in residential and institutional settings.
The Ministry of Commerce and Industry, through its Quality Control Orders (QCOs), has made ISI Mark certification mandatory for all manufacturers of white cement-based polymeric putty under IS 17545:2021. Without this certification, companies cannot legally manufacture, sell, or import this product in India.
To obtain the BIS certification, manufacturers must go through a rigorous conformity assessment process. This involves product testing at a BIS-recognized laboratory, factory inspection by BIS officials, and demonstration of consistent compliance with the IS standard in production processes. Once the license is granted, the manufacturer is authorized to use the ISI Mark, which assures consumers of product quality and compliance.
BIS certification under this standard involves a rigorous conformity assessment process to ensure product quality and adherence to regulatory norms. The steps typically include:
To apply for BIS certification, manufacturers need to submit the following documents:
●Application form
Additionally, manufacturers may be required to provide proof of compliance with environmental and safety regulations, depending on the specific type of product being certified.
For consumers, the ISI mark on a white cement-based polymeric putty pack is a sign of reliability. It guarantees that the product meets defined Indian safety and quality benchmarks. For manufacturers, BIS certification is more than just a regulatory requirement—it is a market differentiator. It builds trust with dealers, architects, contractors, and end-users, and ensures easier acceptance in government and institutional projects.
Moreover, certified products are less likely to face regulatory hurdles or consumer complaints, and they enjoy greater credibility in both domestic and international markets.
White cement-based polymeric putty plays a foundational role in the finishing stages of construction. With the implementation of BIS certification under IS 17545:2021, the Indian government aims to standardize quality, protect consumers, and uplift the overall standard of construction materials used in the country.
Manufacturers aiming to compete in this regulated landscape must now ensure full compliance with IS 17545:2021 and obtain the necessary BIS certification. At EVTL India, we assist manufacturers at every stage of the certification journey—from documentation and testing coordination to factory audits and license acquisition—ensuring a smooth and hassle-free BIS compliance process.
