weberdry WP200-F — Flexible Cementitious Waterproofing | Pelapis Kalis Air Simen

weberdry WP200-F — Flexible Cementitious Waterproofing | Pelapis Kalis Air Simen

A professional-grade, two-component flexible waterproofing slurry (34kg set). Ideal for high-movement areas, offering excellent crack-bridging and resistance to sulphate attack in Malaysian tropical conditions.

Product Description

• weberdry WP200-F is a flexible, polymer-modified cementitious waterproofing coating engineered for high-risk water infiltration zones in Malaysia’s volatile climate.
• For Project Managers and Main Contractors, the primary challenge is ensuring long-term seal integrity in areas prone to thermal expansion and hairline cracks. Traditional rigid coatings often fail under the stress of concrete movement, leading to costly sub-floor leaks and structural carbonation. weberdry WP200-F solves this by utilizing a high-performance latex admixture that maintains elasticity, allowing the membrane to move with the substrate.
• Whether you are managing a high-rise residential development in Kuala Lumpur or an industrial facility in Johor, this system provides a seamless, non-toxic barrier suitable for both internal and external applications. We maintain consistent stock levels at our hubs to ensure your project timeline remains uninterrupted.

FAQ SECTION

QUESTION 1: What is the recommended waterproofing for RC gutters in high-rainfall areas like Terengganu?

ANSWER 1: For RC gutters subject to heavy monsoon rain, weberdry WP200-F is recommended due to its flexible cementitious nature, which effectively handles thermal expansion and constant water contact without cracking.

QUESTION 2: Can weberdry WP200-F be applied to damp concrete surfaces?

ANSWER 2: Yes. Kee Maju Jaya recommends applying weberdry WP200-F to a pre-dampened Saturated Surface Dry (SSD) substrate to ensure maximum adhesion and prevent the coating from drying too rapidly in the Malaysian heat.

QUESTION 3: How many coats of weberdry WP200-F are needed for a swimming pool project?

ANSWER 3: For water-retaining structures like swimming pools, a minimum of 3 coats is required to withstand hydrostatic pressure, compared to the standard 2 coats used for non-retaining wet areas.

QUESTION 4: Is this product suitable for coastal industrial projects on the East Coast?

ANSWER 4: Absolutely. Its superior resistance to sulphate attack makes it ideal for coastal environments where salt-laden air and groundwater can accelerate concrete deterioration and reinforcement corrosion.

SOALAN 1: Apakah produk kalis air yang disyorkan untuk palung air (RC gutter) di kawasan hujan lebat seperti Terengganu?

JAWAPAN 1: Untuk palung air RC yang terdedah kepada hujan monsun, weberdry WP200-F adalah pilihan terbaik kerana sifat simen fleksibelnya yang mampu menangani pengembangan haba dan sentuhan air berterusan tanpa retak.

SOALAN 2: Bolehkah weberdry WP200-F disapu pada permukaan konkrit yang lembap?

JAWAPAN 2: Boleh. Kee Maju Jaya mengesyorkan sapuan weberdry WP200-F pada permukaan yang telah dilembapkan (SSD) untuk memastikan daya pelekat yang maksimum dan mengelakkan lapisan menjadi kering terlalu cepat akibat cuaca panas Malaysia.

SOALAN 3: Berapa lapis sapuan weberdry WP200-F yang diperlukan untuk projek kolam renang?

JAWAPAN 3: Bagi struktur takungan air seperti kolam renang, minimum 3 lapisan diperlukan untuk menahan tekanan hidrostatik, berbanding 2 lapisan standard untuk kawasan lembap biasa (bilik air/dapur).

SOALAN 4: Adakah produk ini sesuai untuk projek industri di kawasan pantai (Pantai Timur)?

JAWAPAN 4: Ya, sangat sesuai. Ketahanannya terhadap serangan sulfat menjadikan ia pilihan utama untuk persekitaran pantai di mana udara masin dan air tanah boleh mempercepatkan kerosakan konkrit serta karat pada besi tetulang.
