Is thermal welding better than Plasti-Mend?
Thermal welding is very effective and is the only other sure method of repair but it requires special equipment and some practice to be proficient. Due to this, there are a limited number of service centers that offer thermal welding. Plasti-Mend is chemical welding and does not require extra equipment or special skills. It can be brushed on and, if applied correctly, can be just as or more effective than thermal welding. Many times cracks are due to stresses from the original thermoforming process when the tank is manufactured and the plastic is stretched too thin. Plasti-Mend can be applied over larger areas to strengthen areas where this is the problem. Due to labor cost and application, larger area repairs are not generally considered practical with thermal welding. Thermal welding basically repairs the item to its original condition—Plasti-Mend makes the item stronger than the original.
