Are you looking for a reliable way to waterproof and protect your concrete structures? Sika Top 107 Plus is a popular choice for its excellent adhesion and durability. In this guide, we'll walk you through the steps on how to use Sika Top 107 Plus effectively, ensuring your projects are well-protected and long-lasting.

    What is Sika Top 107 Plus?

    Before we dive into the application process, let's understand what Sika Top 107 Plus is all about. Sika Top 107 Plus is a two-component, polymer-modified cementitious coating. This means it consists of a powder component (A) and a liquid component (B) that you mix together. It's designed to be applied to concrete and mortar surfaces to provide waterproofing and protection against various environmental factors.

    Key Features and Benefits:

    • Excellent adhesion to concrete and mortar
    • Waterproof and protects against chloride penetration
    • Good resistance to abrasion
    • Easy to mix and apply
    • Non-toxic and suitable for use in contact with potable water

    Common Applications:

    • Waterproofing of basements and retaining walls
    • Internal and external waterproofing of concrete structures
    • Protection of concrete against carbonation and chloride attack
    • Waterproofing of potable water tanks and swimming pools

    Preparing for Application

    Surface Preparation

    The success of any coating application lies in proper surface preparation. Here’s what you need to do:

    1. Clean the Surface:

      • Remove all loose particles, dust, oil, grease, and any other contaminants from the concrete surface. You can use a wire brush, scraper, or even a pressure washer for this step. Make sure the surface is clean and free from anything that could interfere with the adhesion of Sika Top 107 Plus.

    2. Repair any Defects:

      • Fill any cracks, holes, or imperfections in the concrete surface with a suitable repair mortar. Sika offers a range of repair mortars that are compatible with Sika Top 107 Plus. Addressing these defects ensures a smooth and uniform surface for the coating.

    3. Saturate the Surface:

      • Dampen the concrete surface with clean water before applying Sika Top 107 Plus. The surface should be saturated surface dry (SSD), meaning it's damp but without any standing water. This helps the Sika Top 107 Plus bond properly to the concrete.

    Mixing the Components

    Mixing Sika Top 107 Plus correctly is crucial for achieving the desired performance. Here’s how to do it:

    1. Pour the Liquid Component:

      • Pour the entire liquid component (B) into a clean mixing container. Ensure the container is large enough to accommodate both components and allow for thorough mixing.

    2. Gradually Add the Powder Component:

      • Slowly add the powder component (A) to the liquid while continuously mixing. Use a low-speed mixer (e.g., a drill with a mixing paddle) to ensure a homogenous mixture. Avoid adding the powder too quickly, as this can cause clumping.

    3. Mix Thoroughly:

      • Continue mixing for at least 3-5 minutes until you achieve a smooth, lump-free consistency. The mixture should be similar to a thick paint. A well-mixed Sika Top 107 Plus ensures optimal adhesion and waterproofing properties.

    Applying Sika Top 107 Plus

    Application Methods

    Sika Top 107 Plus can be applied using different methods, depending on the project requirements and your preferences:

    • Brush:

      • A brush is suitable for smaller areas and detailed work. Use a stiff-bristled brush to apply the coating evenly. Brushing allows you to get into corners and edges effectively.

    • Roller:

      • A roller is ideal for larger surfaces, providing a faster and more uniform application. Use a medium-nap roller for best results. Ensure you overlap each pass to avoid any gaps in the coating.

    • Spray:

      • For large-scale projects, spraying can be the most efficient method. Use an airless sprayer with the appropriate nozzle size. Spraying requires some experience to ensure a consistent coating thickness.

    Application Steps

    1. Apply the First Coat:

      • Apply the first coat of Sika Top 107 Plus to the prepared surface, ensuring complete coverage. Work the coating into the surface to achieve good adhesion. The first coat acts as a primer and helps to seal the surface.

    2. Allow to Cure:

      • Allow the first coat to cure for at least 4-6 hours, or as specified in the product data sheet. The coating should be touch-dry before applying the second coat. Proper curing is essential for the coating to develop its full strength and waterproofing properties.

    3. Apply the Second Coat:

      • Apply the second coat of Sika Top 107 Plus, again ensuring complete coverage. Apply the second coat in a direction perpendicular to the first coat. This helps to ensure uniform coverage and eliminates any potential weak spots.

    4. Curing:

      • Allow the second coat to cure for at least 24 hours before exposing the coated surface to water or other environmental factors. Keep the coated surface damp during the curing process to prevent premature drying and cracking.

    Post-Application Care

    Curing and Protection

    Proper curing is essential for Sika Top 107 Plus to achieve its optimal performance. Here are some tips for post-application care:

    • Keep the Surface Damp:

      • Regularly dampen the coated surface with water for the first 24-48 hours. This helps to prevent the coating from drying out too quickly, which can lead to cracking. You can use a fine mist sprayer or cover the surface with damp burlap to maintain moisture.

    • Protect from Extreme Conditions:

      • Protect the coated surface from direct sunlight, strong winds, and extreme temperatures during the curing process. These conditions can cause the coating to dry unevenly and compromise its performance. Use tarps or other protective coverings to shield the surface from the elements.

    Inspection and Maintenance

    Regular inspection and maintenance can help to prolong the life of your Sika Top 107 Plus coating:

    • Inspect Regularly:

      • Periodically inspect the coated surface for any signs of damage, such as cracks, blisters, or delamination. Address any issues promptly to prevent further deterioration. Early detection and repair can save you time and money in the long run.

    • Clean as Needed:

      • Clean the coated surface as needed to remove any dirt, debris, or stains. Use a mild detergent and water, and avoid using harsh chemicals or abrasive cleaners. Regular cleaning helps to maintain the appearance and performance of the coating.

    Troubleshooting

    Common Issues and Solutions

    Even with careful application, you might encounter some issues. Here are a few common problems and how to address them:

    • Cracking:

      • If the coating cracks, it could be due to excessive shrinkage or movement in the concrete. Repair the cracks with a suitable repair mortar and apply an additional coat of Sika Top 107 Plus. Ensure the underlying cause of the cracking is addressed to prevent recurrence.

    • Blistering:

      • Blistering can occur if the concrete surface is not properly prepared or if there is moisture trapped beneath the coating. Remove the blisters, clean the surface, and reapply Sika Top 107 Plus. Proper surface preparation and ensuring a dry substrate are key to preventing blistering.

    • Poor Adhesion:

      • Poor adhesion can result from a contaminated surface or improper mixing. Clean the surface thoroughly, ensure the components are mixed correctly, and reapply the coating. Always follow the manufacturer's instructions for mixing and application to ensure good adhesion.

    Safety Precautions

    Important Safety Measures

    When working with Sika Top 107 Plus, it’s important to take the necessary safety precautions:

    • Wear Protective Gear:

      • Wear gloves, safety glasses, and a dust mask to protect your skin, eyes, and respiratory system from the chemicals in the product. Protective gear minimizes the risk of irritation or injury.

    • Work in a Well-Ventilated Area:

      • Ensure adequate ventilation when mixing and applying Sika Top 107 Plus. Avoid inhaling the dust or vapors. Good ventilation helps to prevent respiratory irritation.

    • Follow Manufacturer's Instructions:

      • Always read and follow the manufacturer's instructions and safety guidelines provided in the product data sheet. This ensures you are using the product safely and effectively.
