  • Description

    STAR CEMENT SHIELD - HYDRO is a hardcore, nano-based, hydrophobic coating of ultimate quality for plastered surfaces. It provides protection against water leakage and staining on the walls and surfaces for a number of years without affecting the pristine condition of the surface.

    Star Cement Shield - Hydro is a hydro/aqua version of the popular Star Water Shield, but with a silicon-based added twist, hence making it more powerful in repelling water and keeping your plastered surfaces looking great.

    Star Cement Shield – Hydro is special in that it is versatile. It is suitable for inside use as well as exterior applications. Whether it's your bathroom, kitchen, or an outside wall, this hydrophobic coating will serve as the best protection.

    One of the prime advantages of Star Cement Shield - Hydro is that it can act as an admixture. Application labor has been made simpler with it; one need not lose time on application. Mix with the recommended4 ratio, and brush or roll it on the plastered surface evenly; allow it to dry completely. It's that easy!

Introducing Star Cement Shield - Hydro: The Ultimate Solution for Plastered Surface Protection!

  • Superior Water Resistance

    Star Cement Shield - Hydro shows excellent water-resistance performance, which prevents infiltration of water and thus reduces the subsequent problems related to plastered surfaces.

  • Long-lasting Protection

    The hydrophobic coating forms a strong barrier with long-term effectiveness that ensures protection from water-related problems for years to come.

  • Reduced Maintenance

    Star Cement Shield-Hydro reduces frequent repairs and maintenance by preventing water damage and saves time and money.

  • Improved Aesthetic Appeal

    It enhances the appearance of plastered surfaces by preventing water stains, efflorescence, and other unsightly marks caused by infiltration.


  1. Nano-Based Hydrophobic Technology:

Uses the latest Nano-Based Hydrophobic Technology to provide unmatched resistance to water.
A protective monolayer on the plastered surfaces, the formulation does not absorb water at all.

2. Long-Lasting Protection:

  • Offers long-lasting protection to plastered surfaces, ensuring durability and minimizing maintenance requirements.
  • Resists water-related wear and tear, preserving the integrity of the surfaces over time.

3. Silicon-Based Formula:

Silicon-based formula ensures high performance with no disappointments.
Excellent adhesion, and compatible with most cement and mortar, making it versatile in applications.

  • Walls

    It is suitable for interior and exterior walls, allowing for improved water resistance.
    Protects walls from moisture, avoiding dampening, and ensuring that the structure of the building remains unaffected.

  • Ceilings

    Suggested uses on ceilings to prevent water spots / discoloration from a leak or other water damage.

    Provides long-lasting protection that ensures aesthetic appeal is maintained for the ceiling surface.

  • Facades

    Suitable for building facades to protect them against rainwater and environmental pollutants.
    Maintains the façade appearance and, therefore, enhances the structure's appeal to the eye.

  • Prepare the surface

    The plastered surface must be free from dust, clean, dry, and free from any loose dust or impurities.

  • Mix the product

    Mix Star Cement Shield - Hydro with cement or mortar in a recommended dosage ratio as per manufacturer's recommendation.

  • Apply the mixture

    Apply the mixture evenly on the plastered surface using a brush, roller, or spray equipment.

  • Allow drying and curing

    Allow the coating that has been applied to dry and cure as instructed by the manufacturer before it gets exposed to water.


1. Read Instructions Carefully:

Read the guidelines or the instructions on the product label or manual thoroughly and try to adhere to the guidelines.

2. Protective Gear:

  • Wear appropriate protective gear such as gloves and safety goggles to prevent skin contact and eye irritation.

3. Ventilation:

  • Ensure that there is adequate ventilation provided in the sprayed area. Fumes should be able to disperse in an efficient manner. One can use fans or open up windows indoors to ensure that the air is flowing smoothly.
  • It should not be inhaled. If it becomes necessary to be placed in an enclosed space, then wear an appropriate mask for chemical fumes.

4. Avoid Inhalation:

  • Avoid breathing in the fumes. If working in an enclosed space, consider wearing a mask suitable for chemical fumes.
