How to Apply Torch-On Waterproofing

Torch-on waterproofing is a highly durable and effective solution, especially for flat roofs. It provides long-lasting protection against water damage when done correctly. Below is a step-by-step guide to help you understand the process.

How to Apply Torch-On Waterproofing

1. Surface Preparation

Proper preparation is essential for ensuring the success of your torch-on waterproofing project.

  • Clean the Surface Thoroughly: Start by removing debris, dirt, or remnants of old waterproofing materials. Contaminants can compromise the adhesion of the new membrane, so this step is critical.
  • Ensure the Surface Is Dry and Even: Before proceeding, make sure the surface is completely dry and free of uneven areas. Repair any cracks or imperfections to create a smooth base for the membrane.

By preparing the surface meticulously, you set the foundation for a successful application.

 

2. Primer Application

A primer plays a vital role in ensuring strong adhesion between the surface and the torch on the membrane.

  • Use a high-quality bitumen primer and apply it evenly across the surface using a brush or roller.
  • Allow the primer to dry completely before moving on to the next step. Drying times may vary depending on weather, so always refer to the manufacturer’s instructions for guidance.
 

This step ensures that the membrane bonds securely, enhancing its durability and effectiveness.

 

3. Applying Torch-On Membrane

The application of the torch-on membrane is the core part of the process.

Step 1: Roll Out the Membrane

Begin by unrolling the torch-on membrane onto the prepared surface. Ensure there is an overlap which is specified by the manufacturer between adjacent sheets to create a continuous, watertight layer.

Step 2: Heat and Bond

Using an LPG torch, carefully heat the underside of the membrane as you unroll it. The heat melts the bitumen backing, allowing it to bond securely with the surface. Move the torch evenly and maintain a consistent distance to avoid overheating or damaging the material.

Step 3: Secure Overlaps

Pay special attention to the overlaps between membrane sheets. Heat them thoroughly and press down firmly to ensure a strong, watertight seal. For best results, use a roller or trowel to smooth out the membrane and eliminate air bubbles.

 

4. Final Inspection

Once the membrane is applied, inspect the entire surface for potential issues.

  • Check for air pockets or areas where the membrane may not have bonded properly.
  • Address any defects immediately by reheating and pressing the membrane into place.

Taking the time to inspect and correct any flaws ensures a flawless finish.
