Roof Protection That Stands the Test of Time

Silicone resurfacing and full elastomer refacing are two options used in the coatings and surfacing industry. Each method has its own advantages, and it's important to consider your specific needs before choosing the best option for your situation. Here are just a few of the advantages of silicone resurfacing over full elastomer refacing:

  • Cost: Silicone resurfacing is often less expensive than full elastomer resurfacing. It can be used to repair or renew an existing surface, saving on the labour and material costs required for a complete resurfacing.


  • Installation Time: Silicone resurfacing generally requires less installation time than full elastomer resurfacing. It can be applied directly to an existing surface without the need to remove or completely replace the existing coating.


  • Durability: Silicone is known for its durability and resistance to weathering, UV rays and other environmental factors. A properly applied silicone coating can provide prolonged, effective surface protection, which can reduce the need for future repairs and maintenance.


  • Flexibility: Silicone is a flexible material that can adapt to different shapes and surfaces. It can be used to cover complex structures, such as expansion joints or irregular shapes, more effectively than elastomer, which can require more complex techniques to apply correctly.


  • Chemical Resistance: Silicone has superior chemical resistance to many other materials. It can withstand a wide range of chemicals, acids and solvents, making it an appropriate choice in industrial or chemical environments where chemical protection is required.


It's important to note that every situation is unique, and it's advisable to consult experts in the field of coatings and surface finishes for advice specific to your project.
