Project Description

This packaging facility in Forest Hills, MD has a total roof area of about 114 square which was near the end of its life. Rather than perform a costly, time and labor intensive complete tearoff and re-roof, the owner was able to have this metal roof fully restored with an Armour Proof Coating System. The chosen system to address and restore this roof was a two coat system of Modified Liquid Rubber.

In conclusion, this white, highly reflective, liquid membrane system brought this business a fully restored roof to protect their assets and personnel for years to come!

Surface Preparation

The contractor pressure washed the metal roof surface to remove any loose rust, dirt and debris. Once dry, the contractor applied AP-1100 Rust Inhbiting Primer to prevent any rust from spreading and to prepare the roof for the liquid membrane system.

Seam & Penetration Repair

Fasteners were tightened and or replaced and coating embedded with stitch-bonded polyester fabric was used to reinforce all seals, seams and problematic areas.

System Coating Process

A base coat followed by a finish coat of AP-6100 Modified Liquid Rubber were applied to the entire roof to provides a waterproof, durable, seamless, flexible, weather resistant membrane with excellent elongation, tensile strength and UV protection.
