Concrete Repair

Concrete Repair Products for Commercial & Industrial Projects

A sound, properly prepared substrate is a critical factor in coating and waterproofing system performance. Canopus Supply stocks professional-grade concrete repair mortars, patching compounds, and resurfacing products from manufacturers including MAPEI and Sika — formulated for commercial and industrial repair applications across British Columbia.

Repair product selection depends on substrate condition, defect type, repair depth, and the coating system to be applied over top. Confirm product suitability against the current TDS, SDS, and project specification before ordering.

Product Characteristics

Fast-Setting Mortars — Rapid-set repair mortars formulated for accelerated strength gain; confirm cure times, recoat windows, and compatibility with the planned coating system against the current TDS before use.
Cementitious & Polymer-Modified Formulas — Designed for adhesion to existing concrete substrates; final bond strength depends on substrate condition, surface preparation, and application method.
Coating Compatibility — Repaired surfaces are intended for use with epoxy, polyurethane, and polyaspartic coating systems when applied as directed; confirm compatibility and required cure time against the TDS and coating system documentation before proceeding.
Application Range — Suitable for crack filling, spall repair, feather-edge patching, and full-depth slab repairs on horizontal and vertical surfaces; confirm product suitability for the specific repair type and depth.

Typical Applications

Spall and crack repair on concrete floors and slabs
Substrate levelling prior to coating application
Parkade deck and ramp repairs
Vertical and overhead concrete patching
Joint and control crack filling

Repair Before You Coat

All cracks, spalls, and surface defects should be repaired and fully cured before applying any coating system. Contact Canopus Supply for product selection guidance based on your substrate condition and planned coating system.

Contractor FAQ — Concrete Repair

Do concrete repairs need to fully cure before a coating is applied?

Yes. Repair mortars and patching compounds must reach the manufacturer’s specified cure time and moisture content before any coating system is applied over top. Applying coatings over uncured or damp repairs is a common cause of adhesion failure. Confirm cure time and recoat window requirements against the current TDS for both the repair product and the coating system before proceeding.

What is the difference between a cementitious and a polymer-modified repair mortar?

Cementitious repair mortars are cement-based and suited for structural and semi-structural repairs. Polymer-modified mortars incorporate polymer additives to improve adhesion, flexibility, and resistance to shrinkage. Product selection depends on repair depth, substrate condition, and the coating system to be applied over top. Confirm product suitability against the current TDS and project specification before ordering.

Can repair mortars be used under epoxy or polyaspartic coatings?

Many cementitious and polymer-modified repair products are compatible with epoxy, polyaspartic, and urethane coating systems when properly cured and prepared. Compatibility depends on the specific repair product, the coating system, and the required surface profile. Confirm compatibility against the current TDS for both the repair product and the coating system before ordering.

What surface preparation is required after a concrete repair?

Repaired areas typically require grinding or abrading to achieve the required surface profile (CSP) and to ensure the repair is flush with the surrounding substrate before coating. Confirm surface preparation requirements against the current TDS and coating system documentation before work begins.
