# Industrial Coating Contractors: Who Applies, Who Supervises

Polylloy does not send its own crews: certified partners apply Polylloy coatings, while Polylloy formulates and supplies the material, writes the specification and supervises the application. An industrial coating contractor, or applicator, is the firm that prepares the steel and applies a protective coating on site; on a Polylloy project, that firm is a certified partner.

## Coating Contractors and Supervision: Key Points

- Certified partners apply Polylloy coatings; Polylloy formulates, supplies, specifies and supervises.

- Plants start through Polylloy: request an evaluation, receive a grade and specification, and confirm with Polylloy which certified partner will apply it.

- Polylloy's support covers technical evaluation, system selection, application guidance, inspection and maintenance support.

- Crews need competence in abrasive blasting, two-component mixing, application technique, film-thickness measurement and inspection.

- Heat-cured grades complete final activation during start-up using process heat; CorrosionGard®-160S is ambient-cure.

- Partners operate across the Americas, Europe, Africa, Asia and Australia.

## How Polylloy's Partner Application Model Works

Polylloy's partner application model splits a severe-service coating project between three parties, each with a defined job. Polylloy trains and supports its global partners, but the partners execute the site work.

| Party | Role on the project | Typical deliverables |
| --- | --- | --- |
| Polylloy Coatings | Formulate, supply, specify, supervise | Grade, specification, material, supervision |
| Certified partner | Surface preparation and application | Application quotation, blasting, spraying, quality-control records |
| Plant owner | Access, outage, operating data | Site access, outage window, acceptance |

Settling these lines before mobilization avoids a common site dispute on coating jobs: who owns a surface-preparation defect found at a hold point.

## Does Polylloy Apply Its Coatings or Do Certified Partners?

Certified partners apply Polylloy coatings; Polylloy does not field its own application crews. Polylloy is a research and development (R&D) and manufacturing company in the San Francisco Bay Area, at the heart of Silicon Valley's technology innovation, whose job is to formulate and supply the coating, write the specification and supervise the work.

The partner blasts the steel, mixes and applies the material and records its quality checks. The plant gets manufacturer oversight alongside a regional applicator working to the plant's site safety rules.

## What Does Polylloy Do on a Coating Project If It Does Not Apply?

Polylloy covers the work around the application: technical evaluation, system selection, specification, material supply, application guidance, supervision, inspection and maintenance support. The evaluation looks at the operating envelope: continuous temperature, excursions, gas chemistry, condensation risk and abrasion.

Polylloy then selects a grade by service limit and exposure, from CorrosionGard-160S at 160 °C to WearGard®-625S at 625 °C. Systems matched to specific equipment are described under [custom coating applications](https://www.polylloycoatings.com/custom-coating-applications).

## How Does a Plant Get a Certified Polylloy Application Partner?

A plant gets a certified Polylloy application partner by starting with Polylloy; the partner arrangement for each site is confirmed during the evaluation. The sequence has four steps:

1. Request a coating evaluation with equipment type, coated area, operating conditions, location and outage timing.

2. Polylloy's technical team recommends a grade and writes the specification.

3. Polylloy confirms which certified partner will carry out the application.

4. The partner applies the coating; Polylloy supplies the material and supervises.

## Can Our Own Coating Contractor Apply a Polylloy Coating?

Raise your preferred coating contractor at the evaluation stage and ask Polylloy how it would be treated. Certified partners apply Polylloy coatings, so whether another contractor can take part, and in what role, is a question for Polylloy to answer for your specific job.

Plants with a long-standing site contractor often value continuity in permits and safety induction, which is reasonable to raise early.

## What Does Polylloy Application Supervision Include?

Polylloy application supervision builds on its specification, application guidance and inspection support. The exact scope, including which stages are witnessed and what is documented, is agreed for each project, so write it down before the partner mobilizes.

The practical tool is an inspection and test plan (ITP) with hold points: stages, such as after blasting and after each coat, where work stops until the result is checked and signed. The ITP settles who inspects, who signs and which records the plant receives.

## What Training Does an Application Crew Need for Polylloy Coatings?

An application crew for Polylloy coatings needs competence in abrasive blasting to the specified standard, two-component mixing, application technique, film-thickness measurement and inspection. Surface preparation weighs heavily on the result: FlueGard®-455CHT calls for an SSPC-SP10 near-white metal blast, an SSPC (The Society for Protective Coatings) standard, with a surface profile greater than 3 mils.

Polylloy provides application guidance and training to its partners. For the inspection role, industry certification such as the coating inspector programs of AMPP (the Association for Materials Protection and Performance) or FROSIO, the Norwegian certification scheme for surface treatment inspectors, is widely used good practice.

## What On-Site Technical Support Comes with a Polylloy Coating?

A Polylloy coating comes with technical support across the project: equipment evaluation, system selection, application guidance and supervision, inspection, and maintenance support. How much happens on site, and at which milestones, is agreed per job.

For a first application on a critical asset, plan supervision around surface preparation, the first coat and final inspection. After start-up, ask how [inspection and maintenance support](https://www.polylloycoatings.com/industrial-inspection-maintenance-services) will be scheduled around planned outages.

## How is a Polylloy Coating Inspected Before Start-Up?

A Polylloy coating is inspected against its specification at each stage before the equipment returns to service. Typical checks are surface cleanliness and profile, steel temperature relative to the dew point, wet and dry film thickness, visual defects such as pinholes and dry spray, and holiday testing where specified.

The partner records its quality-control results, Polylloy supervises, and the records go to the plant owner. In flue gas service, missed defects tend to surface first at welds, edges and stiffeners.

## How is Cure Handled When a Partner Applies a Heat-Cured Grade?

Final heat cured activation is completed during start-up using process heat. A heat-cured Polylloy grade therefore finishes curing as the plant comes back on line, which makes the start-up plan part of the coating plan.

Polylloy's technical team agrees the start-up approach for each job. CorrosionGard-160S, by contrast, is ambient-cure and is used on [structural steel, tanks and vessels](https://signals.polylloycoatings.com/comparisons/chemical-tank-lining-hybrid-epoxy).

## Where Do Polylloy's Application Partners Operate?

Polylloy's application partners form a global network across the Americas, Europe, Africa, Asia and Australia. Coatings ship from the San Francisco Bay Area, so projects outside North America should build freight, duties and delivery into the shutdown schedule. Ask during the evaluation which certified partner will serve your site.

## How Can a Specialist Contractor Become a Polylloy Partner?

A specialist contractor interested in becoming a Polylloy partner should contact Polylloy and describe its region, capabilities, equipment and the industries it serves. Useful detail includes blasting and spray equipment, experience with two-component and high-temperature coatings, inspection capability, and recent work in cement, waste-to-energy, power or chemical plants. Polylloy reviews each enquiry directly; its partner selection and certification criteria are not published.

## What Should an Application Quotation for a Polylloy Coating Include?

An application quotation for a Polylloy coating should define the work tightly enough to compare two quotations line by line. Expect it to state:

- Scope and coated area, by equipment item

- Surface preparation standard and profile

- Specified grade and film thickness

- Access, scaffolding and confined-space provisions

- Inspection and test plan, with hold points

- Mobilization, outage duration and exclusions

Pricing depends on the operating environment, selected coating system, equipment condition, project size and application requirements.

## How to Start: What to Send Polylloy

Start by sending Polylloy what it needs to match a grade and a partner: equipment type, coated area, operating temperature range, process chemistry, abrasion exposure, location, outage timing and any preferred contractor. Photos and inspection reports sharpen the evaluation. [Request a coating evaluation](https://www.polylloycoatings.com/contact) to start, and review Polylloy's [corrosion protection solutions](https://www.polylloycoatings.com/corrosion-protection-solutions) to see which product families cover your equipment.

### FAQs

**Will Polylloy Send Its Own Crew to Coat Our Equipment?**

No. Polylloy is a research, development and manufacturing company, and its certified partners carry out surface preparation and application. Polylloy formulates and supplies the coating, writes the specification and supervises the work, so the plant combines manufacturer oversight with a local applicator who knows the site.

**Who Holds the Application Contract on a Polylloy Coating Project?**

Contract structure is agreed for each project, so settle it during the evaluation, before the purchase order is placed. Confirm who contracts the application partner, how coating supply and supervision are ordered, who carries inspection responsibilities, and whether any written warranty applies, with its scope, duration and conditions.

**Who is Responsible If an Applied Coating Fails?**

Responsibility depends on the cause and on the written terms agreed for the project. Surface preparation, application and operating conditions all affect performance, which is why the specification, inspection records and supervision notes matter. Before work starts, confirm in writing whether a warranty applies and, if so, who issues it and its scope, duration and conditions.

**What Surface Preparation Must a Partner Achieve Before Applying a Polylloy Coating?**

Each grade has its own requirement, set in the specification. For FlueGard-455CHT it is an abrasive blast to SSPC-SP10 near-white with a surface profile greater than 3 mils. Poor surface preparation is one of the most common causes of early coating failure, so it is a core supervision point.

**Can Polylloy Supervise a Coating Project Outside North America?**

Polylloy supports projects outside North America through a global partner network across the Americas, Europe, Africa, Asia and Australia. How supervision is arranged for a given site is confirmed during the evaluation. Coatings ship from the San Francisco Bay Area, so plan freight, duties and lead time early.

**How Early Should We Involve Polylloy Before a Shutdown?**

As early as the scope is known. Polylloy needs time to evaluate the equipment and operating data, recommend a grade, confirm a partner and plan material shipment from the San Francisco Bay Area. Freight and lead time are real constraints on outage planning, so engage well before the shutdown date is fixed.

**Is Application Supervision Included in a Polylloy Quotation?**

Pricing is project-specific, so confirm during the evaluation whether supervision is included with the coating supply or priced separately. Pricing depends on the operating environment, selected coating system, equipment condition, project size and application requirements. Installed cost also reflects access, inspection, mobilization and shutdown timing, so ask for each element to be itemized.

**What Information Does Polylloy Need to Recommend a Partner and a Coating?**

Share the equipment type, coated area, operating temperature range, gas or process chemistry, abrasion exposure, project location and outage timing. Photos, inspection reports and coating history help. Polylloy uses this to match the grade by service limit and confirm which certified partner will apply it.

**Does the Partner or Polylloy Inspect the Finished Coating?**

Both have a role. The partner carries out and records quality-control checks such as surface profile, film thickness and visual inspection, while Polylloy supervises against its specification. The plant owner, or its third-party inspector, should receive the records and sign off the hold points in the inspection and test plan.
