RECOAT AND RENEW

Roof refurbishment is increasingly more important in today’s construction world as a sustainable way of extending an existing roof’s lifespan. Buildings are typically built with a design that is intended to have a 50-year life. The roofs on the buildings will most likely need maintenance or refurbishment at certain stages throughout this lifetime to ensure continuous protection against water ingress and other climate-related exposures. One of the biggest advantages of liquid applied membranes is that the existing roof does not need to be torn off to be revived. 

Sika liquid applied membranes are applied directly over the existing roof surface or to the structural deck. An inspection to ensure the substrate’s integrity, a proper cleaning and appropriate primer and the roof can be given a new life with a warranty. The choice is yours to use any of the Sikalastic single-component or two-component systems.

SYSTEM BENEFITS

  • Easy to adjust to complex details
  • Ideal for refurbishment
  • No penetration of the existing roof deck
  • Extend life cycle of old or leaking roofs without interruption
  • Monolithic from substrate, to walls, and around penetration
  • Difficult to access spaces easy to apply

VERSATILITY AND VARIETY

Suitable for a variety of roof structures and substrates, the versatility of a direct to substrate application makes refurbishment easy. Extend and renew your roof’s life by coating existing asphaltic, modified bitumen, single-ply membranes and many others. No tear off, limited or no disruption to occupied buildings, lower costs and a minimal added weight of less then 1 lb. per square foot.

RESIN MEMBRANE OPTIONS FOR DIRECT TO SUBSTRATE APPLICATIONS

One-Component Resin – Polyurethane. Cold applied by roller or spray. Versatile resins, available in standard and custom colors. Lo-VOC options with the ability to be an exposed roofing or protected membrane system.

Two-Component (cold-applied) Resin – Polyurea Hybrids with a Polyaspartic topcoat option. Cold applied by roller or spray. These systems are extremely Lo-VOC resins and can be installed with or without membrane reinforcement. The hybrids are a stand-alone waterproofing option for unexposed systems. Applying the Polyaspartic topcoat creates a UV stable, highly flexible, high gloss finished exposed roof system. 

Two-Component (hot-applied) Resin – Pure Polyurea. This system is installed using specialized heated spray equipment. Trained professionals can use this product in a multitude of unexposed waterproofing projects. The system can be top coated with an overburden or the Sikalastic Polyaspartic topcoat resin.
