"Painting is just another way of keeping
a diary." — Pablo Picasso
Project: 550 Wellington Ave West - Public Art Trellis Pavilion
Client: Soheil Mosun Limited
Type of work: Stripping and refinishing aluminum trellis
PROBLEM
Failing coating on a public art/dining area structure.
ANALYSIS
The structure — designed both as a public art piece and an outdoor dining area for the restaurant Scarpetta — was originally factory powder-coated but the coating began delaminating shortly after installation. It was in a high-profile, high-traffic public area, adjacent to a street and parking lot on one side and a restaurant and reflecting pond on the other.
RECOMMENDATION
The following specification was developed:
Protection - Provide a 16' high shrouded enclosure to protect parked cars, adjacent buildings and pedestrians. Preparation - Remove all of the existing coating back to the original substrate using Devstrip 501 — an environmentally friendly stripper that does not contain methylene chloride, caustics or NMP and is water soluble and biodegradable. The trellis would then be cleaned and neutralized by a high-pressure power wash. Primer Coat - Spray application of Sherwin Williams' DTM Wash Primer — a low VOC, water based wash primer, free of heavy metals and mineral acids. This primer is designed to be applied over aluminum and galvanizing, or used as a tie-coat over zinc-rich primers. The important feature of this primer is that it accepts high-performance "hot" solvent topcoats directly, such as epoxies and urethanes. Finish Coats - A two-coat electrostatic application of Tnemec Series 175 Endura-Shield Acrylic Aliphatic Polyurethane — a coating highly resistant to abrasion, wet conditions, corrosive fumes, chemical contact and exterior weathering. This coating is manufactured with an eggshell sheen to match the original architectural design.
RESULTS
Aesthetics - A low-luster black finish is achieved with this high-performance polyurethane coating. Durability - The polyurethane coating provides superior resistance to weathering. Low environmental impact - The Devstrip 501 was the right tool for this project given the location and presence of both a reflecting pool and young saplings.
