Spray Polyurethane Coating Systems

Spray Polyurethane Foam, commonly referred to as SPF, is an insulating plastic that is sprayed on as a liquid that quickly expands to several times its original thickness creating a water tight roofing material.  It has been used as a roofing and insulation material for over 45 years.  Once applied, the SPF must be coated to further protect the foam from the harmful UV rays.  Once the coating starts to deteriorate and the foam is exposed, water can infiltrate into the roofing system.

Armour Proof Coatings offer an acrylic and urethane/silicone liquid membrane system to coat new and old SPF roofs.

 

Armour Ply 10 – Coating Only System

These systems provide a fully adhered, reflective, liquid coating to protect the roof membrane from further UV degradation. Depending on the slope of the roof, it must be determined whether a water-based or solvent-based coating system should be applied.

Due to the coated surface we recommend an adhesion test to determine which coating to use.

Our systems start by pressure washing the surface to provide a clean, dry and sound substrate.  We offer Primers to enhance and encapsulate the surface. The AP-1200 EPDM Primer/Cleaner is used to assist in the cleaning of black EPDM roof.  The AP-1300 Primer/Sealer is used on asphaltic and previously painted/chalking surfaces.

Once cleaned and primed, the roof is ready for the appropriate roof coating.  The AP-3100 Acrylic Base Coat, AP-3200 Acrylic Finish Coat, AP-6100 Modified Liquid Rubber, AP-5100 Moisture Cure Urethane or AP-5200 Silicone Coating.

 

Armour Ply 20 – Partially Reinforced System

These systems are fully adhered, seamless membranes with superior weatherability. The polyester reinforcement fabric is used at critical areas, such as pipes, curbs, perimeter, and seams. These monolithic, sustainable roofing systems will yield a final minimum membrane thickness of 20 mils throughout the field of the roof and 45 mils at the reinforced area.

The next step is to reinforce the penetrations of the roof.  Us the appropriate coating (determined by the adhesion test) and AP-8100 Polyester Fabric are used around penetrations, seams, laps and other critical areas where movement or splits occur.   AP-3100 Acrylic Base Coat, AP-6100 Modified Liquid Rubber or AP-5100 Moisture Cure Urethane

Once cleaned, primed, and reinforcement have been applied, the roof is ready for the appropriate roof coating.  The AP-3100 Acrylic Base Coat, AP-3200 Acrylic Finish Coat, AP-6100 Modified Liquid Rubber, AP-5100 Moisture Cure Urethane and AP-5200 Silicone Coating.

 

Armour Ply 30 – Fully Reinforced System

These systems are fluid-applied, fully reinforced membrane designed for application to a variety roof substrates. The polyester fabric is used at the critical areas and the entire roof. These systems will provide a fully adhered, seamless and reinforced membrane system throughout the roof with superior weatherability. This monolithic, sustainable roofing system will yield a final minimum membrane thickness of 45 mils.

Once cleaned, primed, and the reinforcement have been applied, the roof is ready for the appropriate roof coating.  The AP-3100 Acrylic Base Coat, AP-6100 Modified Liquid Rubber, or AP-5100 Moisture Cure Urethane are applied to the roof.  While wet, the AP-8100 Polyester Fabric is embedded into the coating.  It is then saturated with more coating.  Once dry, the appropriate Finish Coat is applied.  Two coats of the AP-3200 Acrylic Finish Coat are used over the AP-3100 Acrylic Base Coat.  For low-sloped applications, two coats of either the AP-6100 Modified Liquid Rubber, AP-5100 Moisture Cure Urethane or AP-5200 Silicone Coating are applied.
