Commercial Exterior Painting

Commercial exterior painting in Burnaby requires a fundamentally different approach than interior work. BC's Lower Mainland climate — persistent moisture, freeze-thaw cycling in cooler months, significant UV in summer — means the coating system has to be specified for long-term performance, not just appearance. Burnaby Commercial Painting Co has been painting commercial exteriors across Metro Vancouver through every season, and we know what holds up and what doesn't.

Common Commercial Exterior Substrates in Burnaby

The majority of commercial buildings we paint in Burnaby and the surrounding Metro Vancouver municipalities have one of these exterior substrates: EIFS (Exterior Insulation and Finish System, commonly called "synthetic stucco"), traditional 3-coat stucco, tilt-up concrete panels, concrete masonry units (CMU), fibre cement board (HardiePlank and similar), wood siding, metal panels and cladding, or a combination of these. Each requires different prep, different primer chemistry, and often a different finish coat formulation. A crew that applies one product to all of them is cutting corners.

On EIFS, the critical prep step is replacing all failed acrylic caulk at reveals, windows, doors, penetrations, and control joints. EIFS absorbs water at every joint, and painting over failed caulk simply delays the inevitable — moisture gets behind the coating and the paint starts lifting within one or two seasons. We replace all joint caulk with a commercial-grade polyurethane or EIFS-compatible sealant rated for the exposure, then prime with an EIFS-compatible primer (usually elastomeric) before applying the finish coats.

Why Elastomeric Coatings on BC Exteriors

Elastomeric wall coatings are the correct product for stucco and EIFS on BC commercial buildings. They have an elongation rate of 150–400% — meaning they can stretch and recover without cracking as the substrate moves through temperature changes — and they apply at a significantly higher wet-film thickness than standard latex paint, typically 10–20 mils wet versus 3–4 mils for standard exterior latex. This film thickness provides a waterproof membrane that bridges hairline cracks and resists driving rain penetration. We specify Benjamin Moore MoorElastic, Sherwin-Williams Loxon Elastomeric, or equivalent professional-grade products, applied at the manufacturer's specified coverage rate.

One mistake we see frequently on commercial buildings is standard exterior latex applied over stucco or EIFS without elastomeric properties. It looks fine in year one, develops cracks in year two, and starts peeling in year three — especially on south and west elevations with high UV and thermal load. Using the right product on the front end adds marginally to material cost and saves a full repaint cycle in the medium term.

Access Equipment for Commercial Exteriors

Most commercial exterior work in Burnaby requires some form of elevated access. Single-storey buildings can usually be done from extension ladders and pump jacks. Two- to four-storey buildings typically use scaffolding, swing stage, or articulating boom lift depending on the façade profile, building access, and project duration. Five storeys and above requires swing stage or rope access, both of which require certified operators. Our crew holds Working at Heights certification and swing stage operator tickets. For rope access work on high-rise and complex façades, we either deploy our own rope access team or work in partnership with certified rope access subcontractors.

Weather Windows and Scheduling

Exterior commercial painting in Metro Vancouver is a year-round activity, but it requires careful weather monitoring. Most exterior coatings require a surface temperature between 10°C and 35°C, substrate moisture content below 12–15%, and no rain forecast in the application window. We monitor Environment Canada weather data and adjust scheduling to hit correct application conditions. In winter and early spring, we often schedule exterior painting in the 10 AM–3 PM window when temperatures are highest and surfaces are driest. This is a routine part of commercial exterior scheduling in BC — it's not a reason to push a project to May.
