Peeling paint needs a sound surface. We strip, prepare and recoat exterior concrete walls for commercial properties.
Plan Your Restoration
Concrete coating restoration removes failing paint and incompatible underlying coatings, prepares the concrete, and rebuilds the finish with a suitable primer and paint system. Sigma Painting provides this service for exterior commercial concrete walls across Toronto and the Greater Toronto Area.
When paint keeps peeling, adding another coat may leave the cause in place. We assess what is beneath the finish and scope the preparation before recommending a new coating system.
Featured commercial case study
Peeling concrete coatings restored from the surface up. See how Sigma removed failing paint and the underlying bituminous layer before priming and repainting.
Read the Walmart Case StudyA photograph can start the conversation, but it cannot establish every cause of coating failure. Surface condition and the existing system need to be assessed on site.
This work suits exterior concrete facades at retail stores, shopping plazas, commercial buildings and managed properties. For portfolios with more than one location, each site needs its own assessment.
Access around windows, signs, entrances and customer areas is part of planning the work. Let us know about trading hours, deliveries, tenant needs and any restrictions when requesting an estimate.
Coating restoration is not structural concrete repair or building-envelope waterproofing. Significant concrete deterioration or an unresolved source of water entry needs separate assessment before painting.
The method follows the condition of the wall. Our Walmart projects demonstrate one sequence for an old bituminous layer; another property may need a different approach.
Review the failing coatings, the concrete condition, access and the affected area. Establish what needs removing and whether another underlying issue needs attention first.
Choose a removal method suited to the existing system. On the Walmart work, repeated stripping applications and scraping exposed the bituminous layer for pressure washing.
Clean the concrete and allow for the surface and product requirements before priming. Select the primer for the prepared substrate and intended finish.
Apply the specified finish system with the necessary drying and recoating periods. Confirm the extent of the work and colour requirements before the project begins.
Our documented Walmart restoration work had a reported project cost range of approximately $7,500-$12,000 CAD and took approximately 5-7 days. These figures provide context for that scope, not a standard rate or promised turnaround.
A written estimate should define the removal, preparation and coating scope. Read the Walmart case study for the products and preparation sequence behind those figures.
Sigma works with commercial property owners and managers across the GTA, including Toronto, Durham Region, York Region, Mississauga and surrounding communities. From a single facade to several locations, start with an assessment of the coating and the work each property needs.
It is the removal of failing paint or incompatible coatings from concrete, followed by surface preparation, primer and a new finish system. Sigma provides this service for exterior commercial concrete walls across the Greater Toronto Area.
The cause of the peeling needs to be assessed first. Painting over loose coatings or an incompatible underlying layer leaves that weak base in place. Where removal is needed, the surface must be prepared before a new primer and finish are applied.
Yes. Sigma has completed work at Walmart locations across the GTA involving an old bituminous layer beneath failing paint. On those projects, existing paint and primer were stripped before commercial-grade pressure washing removed the exposed tar-like layer. The appropriate method for another property depends on a site assessment.
The documented Walmart restoration work had an approximate project cost range of $7,500-$12,000 CAD. This is a project example, not a standard package or a per-square-foot rate. The affected area, coating layers, access, preparation and finish specification determine a new quote.
The documented Walmart restoration process took approximately 5-7 days. Other projects vary with the extent of removal, stripping dwell time, weather, drying and recoating requirements, access and the size of the work area.
No. This service restores the paint and coating system on concrete walls. Structural defects, significant concrete deterioration and sources of water entry need separate assessment. A primer does not replace building-envelope repairs.
Yes. Sigma serves commercial properties across the Greater Toronto Area and has carried out this work at multiple Walmart locations. Send the property locations, photographs of the affected walls and any access or scheduling requirements so the sites can be assessed.
Tell us where the coating is failing. Share the property location, a few photos, the approximate affected area and any access requirements. We'll assess the work and prepare a written estimate.
