7 Common Mistakes When Applying Torch on Membrane: A Guide by Chemind Industries
When it comes to waterproofing, applying torch-on membrane is a widely used method due to it’s durability and effectiveness. However, even a small mistake during application can lead to significant issues down the line. At Chemind Industries, a leading manufacturer and supplier of waterproofing products, we have seen it all. To help you avoid common pitfalls, here are the most frequent mistakes made when applying torch-on membrane and how to steer clear of them.
1. Inadequate Surface Preparation
One of the most crucial steps before applying a torch-on membrane is ensuring the surface is clean, dry, and smooth. Any debris, dust, or moisture can hinder adhesion, leading to potential leaks. Always take the time to thoroughly clean the surface and allow it to dry completely. Additionally, repair any cracks or uneven areas to ensure a smooth application.

Always take the time to thoroughly clean the surface and allow it to dry completely. Additionally, repair any cracks or uneven areas to ensure a smooth application.
2. Incorrect Primer Application
Primers are essential for improving the bond between the membrane and the substrate. However, applying the primer incorrectly can negate its benefits. Make sure to choose the right primer for your specific surface and follow the manufacturer’s instructions meticulously. Apply the primer evenly and allow it to dry fully before proceeding with the membrane application.
3. Overheating the Membrane
Torch-on membranes require careful heating to ensure proper adhesion. Overheating can cause the membrane to become too soft or even burn, compromising its integrity. Use the torch with caution, moving it steadily and maintaining an even distance from the membrane. Look for the tell-tale signs of correct heating: a glossy sheen and a slight bubbling of the bitumen.
4. Insufficient Overlapping
Proper overlapping of membrane sheets is vital to create a watertight seal. Insufficient overlap can result in weak spots and potential leaks. Ensure that each sheet overlaps the previous one by at least 75-100 mm. Pay special attention to the edges and corners, where leaks are most likely to occur.
5. Ignoring Safety Precautions
Torching involves working with an open flame, which inherently carries risks. Failing to follow safety protocols can lead to accidents, injuries, or even fires. Always wear appropriate protective gear, work in well-ventilated areas, and keep a fire extinguisher nearby. Make sure to follow all safety guidelines and regulations to protect yourself and those around you.
6. Rushing the Job
Applying a torch-on membrane requires precision and patience. Rushing the job can lead to mistakes that are costly to fix later. Allocate ample time for each step of the process, from surface preparation to final inspection. Quality work takes time, and cutting corners can compromise the effectiveness of your waterproofing.
7. Neglecting Regular Maintenance
Once the membrane is applied, regular maintenance is key to ensuring its longevity. Periodically inspect the membrane for any signs of wear, damage, or leaks. Address any issues promptly to prevent minor problems from becoming major ones. Proper maintenance can significantly extend the life of your waterproofing system.
