Overview
Induscoat applies protective coating systems to steel, concrete and piping in industrial plants across Quebec and Ontario: corrosion protection for structures, internal linings for tanks and vessels, and repair of coatings in place. The system is chosen for the actual service, the surface is prepared to the specified grade, and every step is checked and recorded.
Induscoat applies and supplies protective coating systems for demanding industrial environments. Our portfolio includes cold-curing epoxy repair compounds, high-performance polymers, corrosion-resistant linings and Induscoat formulations. Each application is documented against the specified surface-preparation, thickness, adhesion and quality-control requirements. Whether you need flange-face repair, tank lining or high-temperature stack protection, we select the system according to the documented service conditions.
What the service covers
The service covers applying coating systems to operating or new assets, at your plant or in a shop, to protect against corrosion, chemical attack and abrasion. We work as the applicator: we prepare, apply, inspect and document.
- Structural steel, frames, walkways and pipe supports: multi-coat corrosion protection systems for atmospheric exposure (corrosion protection).
- Interiors of tanks, vessels, bins and sumps: linings for immersion or chemical contact (tank lining).
- Concrete: process slabs, containment bunds, sumps and trenches (concrete protection).
- Piping and fittings: exterior, field joints and accessible interiors (pipe coating).
- Coating repair in place: spot repairs and restoration of degraded areas without dismantling the equipment.
What is not included: design and installation of cathodic protection (we coordinate with the specialist), certified third-party inspection (we prepare the records for the inspector), structural weld repair and insulation work. Rebuilding worn parts with filled epoxy belongs to our maintenance and rehabilitation service.
Choosing the system for the service
The choice starts from the service the coating will see, not from a product data sheet. Five questions point to the right system family:
- Atmospheric: which ISO 12944 corrosivity category, from C1 to CX, and what durability target? We select a primer, intermediate and topcoat system to match (ISO 12944 explained).
- Immersion: raw water, process water, brine or slurry in permanent contact? ISO 12944 has separate immersion categories; the answer moves to high-build solvent-free epoxies or dedicated internal linings (industrial tank lining selection).
- Chemical: which product, what concentration, what temperature? Acids and solvents point to novolac epoxies or vinyl esters; compatibility is checked against the manufacturer's chemical resistance chart.
- Abrasion: slurry, aggregate, impact? A ceramic-filled epoxy or an elastomer outlasts a thin film; beyond that, alumina tiles or wear parts take over.
- Temperature: hot service, thermal cycling, steam-out cleaning? Every product has its own service limit, which differs between dry and immersed conditions.
Then come the site constraints: achievable surface preparation (abrasive blasting or power tools), temperature and humidity during application, cure time available before return to service, and confined-space access. A system that performs on paper but cannot be applied properly inside the shutdown window is the wrong system. Options are compared over the full life cycle, not on price per litre.
How a coating job runs
- Site assessment: condition of the substrate and existing coating, degradation mechanism, service conditions confirmed with operations.
- Technical quote: proposed system (coats and thicknesses per the product data sheet), preparation grade, planned inspections and hold points where you sign off before work continues.
- Preparation: degreasing, blasting to the specified grade, profile and soluble salt measurements, protection of adjacent areas.
- Application: monitoring of dew point, relative humidity and substrate temperature, recoat windows respected, stripe coats on edges, welds and bolting.
- Inspection: thickness, continuity and adhesion per the specification.
- Handover: records, application log, product data sheets and batch numbers, recommendations for the next inspection.
Quality control and documentation
Acceptance criteria come from the project specification or the manufacturer's data sheet; we do not make them up. Common reference standards:
- ISO 8501-1 and SSPC-SP 10 / NACE No. 2: blast-cleaning grades for steel (NACE No. 2 surface preparation guide).
- SSPC-SP 13 / NACE No. 6: surface preparation of concrete.
- ISO 8502: surface cleanliness before painting, including soluble salts and dust.
- ISO 8503 and ASTM D4417: surface profile.
- SSPC-PA 2 and ISO 19840: dry film thickness measurement.
- NACE SP0188 (steel) and ASTM D4787 (concrete): holiday (continuity) testing.
- ASTM D4541 and ISO 4624: pull-off adhesion testing, which is destructive, so it is done on test panels or agreed locations.
These records make up the QA/QC dossier handed over with the work. They then become the baseline for inspections and the next maintenance campaign.
Planning around your shutdowns
In Quebec and Ontario, most internal tank and vessel linings are done during planned spring or fall shutdowns, sometimes in winter. The lining is planned with the shutdown, not after it: draining, cleaning, confined-space entry, scaffolding and cure take up as much of the window as the application itself.
Winter adds a constraint: air and substrate must stay within the product's application range, which means heated enclosures and dehumidification. Outside shutdowns, maintenance painting of exterior structures is done in the warm season, zone by zone, without stopping production.
What we ask for up front: drawings or field measurements, coating history, service conditions, window length and access constraints. With that in hand, the quote sets out what is done during the shutdown and what can be prepared beforehand.
When a coating is not the right answer
- Loss of structural thickness: if the remaining metal no longer meets minimum thickness, a fitness-for-service assessment and mechanical repair come first. A coating protects; it does not restore lost strength.
- Local wear on parts (impellers, pump casings, shafts, flange faces): rebuilding with filled epoxy falls under maintenance and rehabilitation.
- Part too worn to rebuild: replacement with a foundry casting or custom parts fabrication.
- Large buried or submerged structures: coating is part of the answer, but cathodic protection is designed with a specialist.
- Unresolved process cause (temperature out of range, changed product): without a fix, a new coating will fail the same way. We will tell you before we quote.

Service FAQ
What's the difference between ceramic coatings, polymer coatings and alumina tile solutions?
Ceramic coatings are thin engineered films applied by spray or trowel to rebuild eroded surfaces and resist moderate abrasion. Epoxy and vinyl ester polymer coatings form thick chemical-resistant barriers. Alumina tile solutions protect severe-wear areas such as chutes, cyclone inlets and elbows. We select the system according to the wear mechanism and service conditions.
Do you supply foundry castings and machined parts alongside coatings?
Yes — for severely worn components where coating alone is not enough, we supply foundry castings and handle the design and fabrication of custom machined parts. This integrated supply chain means we can rebuild complete assemblies — coated, cast or machined — under one QA/QC dossier.
Which coating manufacturers do you work with?
Induscoat selects cold-curing epoxy repair compounds, high-performance polymers, corrosion-resistant linings and Induscoat formulations according to the application. The proposal identifies the selected product documentation, application requirements and applicable warranty conditions.

Wastewater concrete corrosion: how H2S attacks concrete, and how to repair and line wet wells, pits and channels
In industrial effluent systems, the worst concrete damage is rarely below the water: it is above it, where hydrogen sulfide escapes and bacteria turn it into sulfuric acid. This guide explains the mechanism, where it concentrates, how to assess the damage, and how to repair the concrete and select a lining that survives a wet, acidic, hard-to-isolate structure.
10 minPower tool cleaning: SSPC-SP 3, SP 11 and SP 15 when blasting is not an option
When abrasive blasting is ruled out by a running plant, a dust ban or a small repair, the specification has to name a power tool grade instead. This guide compares SSPC-SP 2, SP 3, SP 11 and SP 15, their approximate ISO 8501-1 counterparts, the tools that reach each grade and the coating systems that can live with them.
10 minCoating failure analysis: how to diagnose blistering, delamination, cracking and other coating defects
Every coating defect points to a cause: salts left on the steel, a missed recoat window, too much film, too little at the edges. This guide describes what each failure looks like, its probable causes, the test that confirms it and the repair that keeps it from coming back, then sets out the field method for a coating failure analysis.

Cathodic protection makes buried or immersed steel the cathode of a cell so that it stops corroding. This guide compares sacrificial anodes and impressed current, shows where each is used, and explains why the coating and the CP system have to be selected together. It also covers cathodic disbondment, overprotection, interference, measurements and maintenance.

10 minSalt spray vs cyclic corrosion testing: which test to require to qualify a coating
A coating specification that asks for "salt spray hours" and nothing else qualifies very little. Continuous salt fog and cyclic corrosion tests answer different questions. This guide compares the two families, explains why continuous fog often ranks coatings differently from the field, and shows how to write a test requirement that a laboratory can execute and a reviewer can check.
