SKIS Painting worked with Concrete Restoration Inc. to repair and paint three concrete tilt-up buildings that were built in the mid-1990s. Each building was severely affected by chronic water intrusion, causing cracking on numerous walls at all elevations.

In order to ensure success, SKIS evaluated the performance of a mock-up elastomeric coating over one year. With amended specs based on the mock-up, SKIS commenced work.

The team first pressure washed each building to remove mold and mildew. Concrete Restoration then injected epoxy into 1,250 linear feet of cracks, and SKIS ground and scraped the injection areas, patching all hairline cracks with a knife grade elastomeric patching compound.

A key part of the project was removing and replacing the joint sealants. In order to access the tilt seam joints, the team carefully removed the gutter scuppers and downspouts, some more than 30 feet long, and installed through penetrations in the steel canopies. Once it had access to the seam joints, SKIS cut out the old sealants and primed the raw tilt seams before filling them with backer rod.

The new sealants have a uniform, cross-sectional shape and depth, completely filling the recesses in the joint configuration.

With prep work complete, the team applied two coats of elastomeric paint with a continuous uninterrupted wet-edge spray and back-rolled in. WJE Engineers and Sherwin Williams conducted extensive field quality control testing to certify the consistent thickness and coating adhesion.

Downspouts and gutters were reinstalled and sealed at potential water intrusion points during the final phase of the project.

SKIS' work not only protects the buildings from further damage, but the accent stripes painted around the exterior and high-quality finishes complete a clean and professional appearance.

The project was completed 24 days ahead of schedule and more than $109,000 under budget. There were no medical or time-loss incidents in the 2,692 hours worked.
