How to Waterproof Fibre Cement Sheeting

Waterproofing is an essential step when using fibre cement sheeting in areas exposed to moisture, such as bathrooms, kitchens, and external cladding. Proper waterproofing not only enhances the durability of your fibre cement but also ensures a longer lifespan for your construction project. Here's a comprehensive guide on how to effectively waterproof your fibre cement sheeting.

Tools and Materials Needed

  • Waterproofing membrane
  • Reinforcing tape or mesh
  • Paint roller or brush
  • Silicone sealant
  • Gloves
  • Safety goggles

Step-by-Step Guide

Step 1: Surface Preparation

  1. Clean the Surface: Make sure the fibre cement sheeting is clean and dry. Remove any debris, dust, or grease.
  2. Inspect for Damage: Check for any cracks or holes and fill them with silicone sealant.

Step 2: Apply Reinforcing Tape or Mesh

  1. Measure and Cut: Measure the joints and intersections where sheets meet. Cut reinforcing tape or mesh to fit these areas.
  2. Place the Tape: Apply the tape or mesh over the joints, pressing it firmly into place.

Step 3: Apply the First Coat of Waterproofing Membrane

  1. Stir the Membrane: Stir the waterproofing membrane in its container to ensure a uniform consistency.
  2. Apply: Using a paint roller or brush, apply a generous coat of the waterproofing membrane over the entire surface, including over the reinforcing tape or mesh.
  3. Let It Dry: Allow the first coat to dry according to the manufacturer's instructions.

Step 4: Apply the Second Coat

  1. Apply: Once the first coat has dried, apply a second coat of the waterproofing membrane.
  2. Direction: Make sure to roll or brush in a direction perpendicular to the first coat to ensure maximum coverage.
  3. Let It Dry: Allow the second coat to dry according to the manufacturer's instructions.

Step 5: Seal the Edges

  1. Apply Sealant: Use silicone sealant to seal all edges and corners for added protection.
  2. Smooth It Out: Use a spatula or your finger (while wearing gloves) to smooth out the sealant.
