CONSTRUCTION INSTRUCTIONS

Surface Preparation:

Before you begin the installation of Sika® Glass Mesh, thorough surface preparation is essential. Follow these steps:

• Ensure that the surface is clean, free from dust, debris, and any contaminants. Use a broom, vacuum, or compressed air to remove loose particles.
• Repair any existing cracks, holes, or defects in the substrate using an appropriate patching or filling compound. Allow these repairs to cure completely according to the manufacturer’s instructions.
• Check the surface for moisture or dampness. It should be completely dry before proceeding with the installation.

Priming (if required):

• Depending on the specific conditions and the type of substrate you are working with, you may need to apply a primer. Sika provides a range of suitable primers for various substrates. Follow the manufacturer’s guidelines for the chosen primer.

Application of Waterproofing Membrane:

Apply the Sika® Roofseal or Sika® Acrylic Elastic waterproof membrane according to the manufacturer’s instructions. Pay close attention to the following:

• Use the appropriate tools, such as a brush or roller, for applying the membrane evenly and consistently.
• Follow the recommended coverage rates and thickness to ensure proper waterproofing performance.
• Overlap the membrane at seams and edges as required for a continuous and leak-proof barrier.

Positioning Sika® Glass Mesh:

Now, it’s time to install Sika® Glass Mesh over the freshly applied waterproof membrane. Here’s how to do it correctly:

• Unroll the Sika® Glass Mesh over the waterproof membrane, ensuring it covers the areas where additional reinforcement is needed, such as construction joints, cracks, and corner fillets.
• Position the mesh with care, making sure it aligns properly with the intended coverage area.
• Allow for an overlap of at least 50mm (2 inches) at the seams or edges for secure adhesion and improved performance.

Secure the Mesh:

To ensure the Sika® Glass Mesh adheres effectively to the waterproofing membrane:

• Gently press the mesh into place with a suitable tool or your hands.
• Work from the center towards the edges to remove any air bubbles and wrinkles.
• Ensure that the mesh lays flat and smoothly on the membrane surface.

Edge Sealing:

To guarantee the waterproofing system’s integrity, seal the edges of the Sika® Glass Mesh:

• Use a compatible sealant recommended by Sika to secure the edges of the mesh, preventing any water ingress.
• Apply the sealant in a consistent and continuous bead, fully covering the edges of the mesh.

Final Inspection:

Once you’ve installed the Sika® Glass Mesh, conduct a thorough final inspection to ensure a successful application:

• Carefully check the entire mesh installation to ensure it’s securely adhered to the waterproof membrane without any loose areas.
• Confirm that all edges are sealed with the recommended sealant.
• Look for any air bubbles, wrinkles, or imperfections and address them as needed.

Following these detailed construction instructions will help you achieve a flawless installation of Sika® Glass Mesh, enhancing the waterproofing performance of your roofing project and ensuring long-lasting protection against water intrusion.
