  6. Sidewalks 

How to apply

  • Surface preparation

    • A clean, sound surface with a good mechanical key is the goal of surface preparation. Dust, plaster, oil, paint, grease, corrosion deposits, and any other harmful materials should all be removed from substrates.
    • Joints to be opened until mother slab and packed with 25 mm backer rod, ensuring gap-free packing.
    • On metal surfaces, remove scale, rust, or other coatings to expose a bright white surface.

  • Mixing

    • Before mixing, shake Star Expansion Shield briefly until homogenous, then pour into the mixing container and thoroughly mix and stir for at least 2 minutes using a slow speed (300-400 RPM) drill machine attached with a mixing paddle.   

  • Application

    • Fill the joint with pour grade/ gun grade sealant Star Expansion Shield with a minimum depth of 20mm and level with a spatula or putty blade; vertical joints shall be filled with gun grade.

Benefits

  • Elasticity

    It is designed to be highly elastic, allowing it to stretch and compress as the joint moves without losing adhesion or integrity.

  • Weather Resistance

    It is formulated to withstand harsh weather conditions, including UV exposure, rain, and extreme temperatures, ensuring long-lasting performance.

  • Low Dust and Dirt Pick-Up

    Exhibits less dust and dirt accumulation during cure and throughout its lifespan.

  • Movement Accommodation

    It effectively accommodates the movement of building materials due to temperature changes, preventing cracking and structural damage.

  • High Bond Strength

    Offers superior adhesion to a wide range of materials, ensuring long-lasting performance.

  • Paintable

    Can be painted over with most coatings and paints without the risk of delamination.

  • Versatile Applications

    Suitable for sealing expansion joints in pavements, sidewalks, balconies, and other horizontal as well as vertical joints.

  • Water Resistance

    Utilizes advanced nano-based technology to create a robust barrier against water, preventing moisture infiltration and protecting the underlying substrate
