Dry mix plaster is a modern, factory-made plaster that offers superior quality compared to traditional site-mixed plasters. At Precise Conchem, our Silico-Plast Polymerised Drymix Plaster combines cement, graded sand, and performance-enhancing additives to deliver a ready mix plaster that is water-resistant, crack-resistant, and ideal for both internal and external plaster for walls.
Our Dry Mix Plaster is a high-performance, factory-made plaster designed to deliver superior strength, smooth finish, and long-term durability for every type of construction project. This advanced ready mix plaster combines premium cement, graded sand, polymers, and additives to create a reliable cement-based plaster suitable for internal walls, external walls, and ceilings. With a perfectly optimized ceiling plaster ratio, the product ensures excellent workability and adhesion, even on challenging ceiling surfaces.
As a leading readymix plaster manufacturer, we provide ready made plaster that eliminates the inconsistencies of traditional site-mixed plaster. Our Dry Mix Plaster offers a consistent blend that improves application speed, reduces labour, and minimizes material wastage. The mix is engineered as a water-resistant plaster, making it ideal for damp areas and long-lasting external finishes. Builders across India prefer our high-quality external plaster for walls because it resists cracks, shrinkage, and harsh weather conditions while delivering a premium finish.
Whether you’re working on residential, commercial, or industrial projects, this ready mix plaster ensures exceptional bonding, excellent coverage, and smooth surface preparation before painting or coating. Our carefully formulated ceiling plaster for construction use maintains the right balance of strength and flexibility, providing a flawless finish on all ceiling applications.
With our commitment to quality, precision, and performance, we continue to be among India’s most trusted readymix plaster manufacturers, delivering top-grade cement-based plaster, reliable ready made plaster, and durable water-resistant plaster for walls, ceilings, and external surfaces. Choose our Dry Mix Plaster to achieve outstanding finishing, consistent quality, and long-lasting protection for every construction project.
Our polymerised drymix plaster is highly versatile and can be used in a variety of construction scenarios:
Internal wall plastering — creates a smooth, durable surface ideal for painting or tiling.
External wall finishing — provides water-resistant, weather-durable protection.
Ceiling plaster for construction use — particularly useful for ceilings in residential & commercial buildings.
Waterproofing systems — as part of water protection schemes, thanks to its water-resistant properties.
Repair and renovation — works well when re-plastering older structures or applying a high-quality external finish.
Foreign materials/particles that may affect adhesion must be removed. For the RCC substrate, the surface should be thoroughly cleaned by a wire brush so that mold oil, grease, dust, dirt, etc., are completely removed. Then the surface should be cleaned/washed with water. A suitable bonding coat is to be applied, followed by a layer of chaat (key) coat made up of silico Plast for proper adhesion to concrete. It is important to use chicken Mesh/PRM (Plaster Reinforcement Mesh) at the junction of concrete surfaces and masonry walls. This chicken mesh should be fixed in such a way that 50% of its width covers the concrete surface and the remaining 50% covers the masonry wall, with the junction exactly at the centre of the chicken mesh. The initial plastered coat should ensure that the chicken Mesh/PRM is completely embedded in the plaster.
For a surface/substrate made of brick/block masonry walls, the surface should be well-saturated/wet with fresh water before applying the plaster. All masonry joints should be properly filled and raked. The substrate on which silico Plast is to be applied should be in a touch-dry condition.
Take 6 to 6.5 liters of potable water for one full bag of 40kg silico Plast powder. Pour ¾ of the water into a mixing tray. Add half the quantity of silico plast and start mixing. Add the remaining quantity of silico plast quickly and again mix thoroughly until a smooth, creamy, lump-free, homogeneous, and cohesive consistency is achieved. For proper activation of additives/polymers in silico plast, allow the mixture to rest without disturbing it for 2 minutes. If necessary, mix it with a little extra water to achieve the required consistency.
Silico plast should be applied within 60 to 90 minutes of its preparation. Ensure that the thickness of a single coat/layer does not exceed 13mm to 15mm per day. For thicknesses above 15mm, combing of the previous layer of silico plast is essential for better bonding of the next layer.
For external plastering, two layers of total thickness 20mm – 25mm should be applied. The first layer of 12mm is applied with mechanical roughening using ms wire, and after 2 days of curing, the second layer (8mm to 10mm) is applied on the dried first surface layer.
Do not expose silico Plast bags to direct sunlight, rain, moisture, or open-air while in storage or on-site.

Ready-made plaster is a pre-mixed, factory-produced plaster that requires only the addition of water before application. It comes in different types, including polymerized dry mix plaster for durability and crack resistance, gypsum plaster for interior smooth finishing, and cement-based plaster for both internal and external walls. This type of plaster ensures uniform quality, faster application, and better bonding strength than traditional site-mixed plaster.
