Some Background
The two broad categories of asphalt roofing systems for commercial, industrial and institutional buildings are Built-Up Roofing (BUR) and Modified Bitumen Systems (MBS).
Asphaltic roofing products have long been used as protective waterproof coatings on many different types of roofs. Built-Up Roof (BUR) and Modified Bitumen (Mod Bit) Membranes, available in smooth surface and granulated mineral surfaces, are typical asphalt roof membranes. As these roofs age, weathering can shorten the life expectancy of the roof system. Loss of flexibility, shrinkage, cracking, splitting of seams/laps, blisters and drying out of the roof membrane could result in water infiltration. Premature aging from excessive heat, and expansion and contraction add to further problems.
United Asphalt‘s Armour Proof Coating Systems offer solutions for these asphaltic roof problems. We can design a system to meet both your needs and budget and these processes can be done several times avoiding the need for a costly tear-off.
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.
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-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.AP-3100 Acrylic Base Coat and AP-3200 Acrylic Finish Coat are used over most roof systems. For low-sloped applications, we offer AP-6100 Modified Liquid Rubber, AP-5100 Moisture Cure Urethane and AP-5200 Silicone Coating. |
Armour Ply 20 – Partially Reinforced System
These systems are fully adhered, seamless membranes with superior weatherability. 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.

Reinforce the seams and penetrations of the roof.AP-3100 Acrylic Base Coat and AP-8100 Polyester Fabric are used around penetrations, seams, laps and other critical areas where movement or splits occur. |

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.

Add Structure to the First CoatingWhile wet, embed AP-8100 Polyester Fabric into the coating and then saturate with more coating. |
|
Finish Things OffOnce dry, the appropriate Finish Coat is applied. Two coats of AP-3200 Acrylic Finish Coat are used over the AP-3100 Acrylic Base Coat. For low-sloped applications, two coats of either AP-6100 Modified Liquid Rubber, AP-5100 Moisture Cure Urethane or AP-5200 Silicone Coating are applied. |
