Description
UNIV®-PS is a high-quality, premixed Silica (SiO2 98%+) adhesive compound, ideal for both external and internal plastering. Suitable for manual or machine-based applications, it ensures consistent quality. UNIV®-PS is a single-component, water-resistant, monolithic plastering/rendering mixture, combining pure silica, cement, and adhesive compound, designed for civil construction works.
UNIV®-PS stands out for its superior quality, ease of use, and long-lasting protective features, making it an excellent choice for modern construction needs.
Reference Standard
- IS 1661:1972
- IS 2250:1965
- IS 2402:1963
Area of Application
UNIV®-PS is designed to protect walls from external UV rays, dampness, shocks, rain, humidity, fire, and sound, while also providing thermal insulation. It serves as a protective covering, ensuring long-term durability. UNIV®-PS is suitable for application on brick, concrete block, AAC block, fly ash block, and concrete surfaces.
Benefits
- Structural Integrity: Silica is a key structural component in construction products such as flooring, mortar, cement, roofing shingles, asphalt, and other industrial materials. It enhances durability and structural integrity.
- Low Corrosion: Silica is resistant to weathering, wear, and corrosion.
- High Purity: Silica sand contains high levels of silica, ranging from 95% to 99%, unlike regular sand which may have impurities like clay, silt, or other minerals.
- Easy Application: The material is premixed, requiring only the addition of water on site, simplifying and accelerating the plastering process.
- Minimal Cracks: The silica-based compound provides ultimate strength and strong bonding, reducing shrinkage cracks due to accurately tested and mixed raw materials with specific particle size and quantity ratio.
- Better Coverage: The premixed formula ensures better spread and application.
- Smooth Finish: Excellent surface finish due to optimal particle size grading, maximizing wall plaster performance and reducing the need for additional wall putty and paint.
- Eco-Friendly: Contains no fly ash or slag

Limitations or Restrictions
- Avoid direct application to gypsum plaster or boards, fiber cement boards, drywall partitions, plywood, chipboard, particleboard, decorative laminates, resilient flooring, metal, plastic, deformable surfaces, or surfaces subject to vibrations.
- Not suitable for fixing artificial, nano, engineered stone, composites, or metal tiles.
How toApply: -
Surface Preparation- Prepare the surfaces before the UNIV® - PS application by removing oil, bond inhibiting agents, dirt, dust and laitance.
The cleaning can be carried out with suitable methods like by using wire brush, water jetting,mopping, etc.
Mixing- UNIV®-PS requires 17-19% of Normal Waterby weight of material (Example for 40kg Bag requires 6.0 to 7.0 Litre ofWater.)
Mix UNIV®-PS to the measured quantity of water using mechanical stirring for 2-3 minutes to ensure a consistentlump-free mixture.
Application- UNIV®-PScan be used by mortar trowels, spatula and can also be applied by normal masons generally used for conventional plastering.It is ideal for plaster spraying machine.
For thickness above 12 mm it is recommended to be applied in multiple layers.
Curing- Water Curing is required for 2 to 3 time a day up to 7 days from application.
Precaution–safety
As per health & safety rules. Use of safety accessories is required, which includes:
Safety gloves
Safety goggles
Dust &nose mask
Helmet
In case of accidental contact with eyes of either dry or wet mix, immediately wash your hands; make sure your hands are clean and then wash your eyes with clean water and if required, seek medical assistance.
Avoid breathing dust.
