Corrosiveness Factors

1 C1 – Very Low Dry environment with no attack from corrosive chemicals and / or micro-organisms. Routinecleaning (not more than once a month) using neutral cleaning agents.

2 C2 – Low Environment where condensation may occur, with no attack from corrosive chemicals and / ormicro-organisms although the walls may occasionally be splashed with slightly corrosive liquids.Routine cleaning (not more than once a month) using neutral cleaning agents.

3 C3 – Medium Environment with frequently high humidity and where corrosive chemicals and / or micro-organismsare present. Non-intensive cleaning (not more than once a week) using higher pH cleaning agents.

4 C4 – High Environment with constant high humidity and where high concentrations of corrosive chemicals and/ or micro-organisms are present. Intensive cleaning (not more than once a day) using higher pHcleaning agents (pH 5-9).

5 C5 – Very High Environment with permanent condensation and where high corrosive chemicals and / or micro-organisms are present. Intensive cleaning (not more than once a day) using higher pH cleaningagents (pH 5-9).

Controlled environments take many different forms and the performance andfunctionality (in-use) will depend on the requirements of the specific project.The internal environment will also be subjected to a variety of conditions whichcould affect the performance of materials and systems.

BS EN ISO 12944-2 defines and grades corrosiveenvironments in five classes (C1 – C5) depending on theirexposure to corrosion factors and is an indication of theconditions that the coating is designed to resist forextended periods.

The corrosive factors of an internal environment aredetermined by the presence of corrosive chemicalsand / or micro-organisms in the internal atmosphere,relative humidity and also by the frequency of cleaning,aggressiveness of the cleaners, degreasers and sanitisersand method of cleaning.

Regular inspection and maintenance will ensure that the performance of theinsulated panels are maintained. The frequency of inspection is defined bythe corrosive environment classification and type of activities. The table belowprovides a simple checklist along with the action required.

NoteAesthetic appearance is not included as a durability requirement.

Building owners should record details of the building andkeep a record of inspections and maintenance. This is animportant part of the documentation for any building, butparticularly for the buildings registered under the KingspanTotal Panel and Coatings Guarantee.

Corrosiveness Factors

To be checked Actions

Dirt retention– could cause breakdown of the coating.

Clean, see “Cleaning” section.

Condition of coating– (cracks, flaking, discolouration)

Assess extent, severity and type of damage, see“Repair” section.

Scratches & dents– could cause corrosion of metal substrate.

Assess extent and type of damage, see “Repair” section.

Flashing fixing screws– faulty or inappropriate fasteners can cause rust staining,

or mechanical failure, or both.

Check the grip of the screws. If loose and not possible totighten, replace with larger screws.

Trims & flashing tightness– loose trims or flashings can cause instability, or affect

the vapour performance, or both.

Check that the flashings are tight against the panel.If there is a gap, add flashing fixing screws.

Cold bridging– could cause condensation, or ice formation.

Should be immediately addressed. Consult specialistconsultant or manufacturer

Pressure relief valves– could cause structural failure.

Check condition of pressure relief valve. Repair orreplace.

Door operation, seals & heaters Check condition and repair or replace.

Suspension system– could cause structural failure, collapse of ceiling.

Check condition of suspension system and associateditems. If there are any signs of deterioration, repair orreplace. Check the tension of suspension rods. If loose,tighten to correct tension.

Penetrations Check condition around penetrations particularly, vapourseals, infill insulation, pipe lagging etc., repair or replace.


Cleaning

To maximise performance and maintain high standards of hygiene, it isnecessary that the coatings are cleaned using the recommended proceduresdescribed below. The frequency of cleaning and cleaning agents used isdictated by the types of activities conducted in any given area.

Cleaning and disinfecting should usually be done asseparate processes. A surface needs to be thoroughlycleaned before it is disinfected.

Definitions:Clean means “clean to touch”, which is, free from any dirt,dust or food particles that you can see and does notnecessary smell. Cleaning is the removal of these particlesand / or smells.

Disinfecting means apply heat and / or chemicals to asurface so that the number of bacteria on the surface isreduced to a level that is safe for food contact.

1. Pre-clean: Spray all surfaces with a diluted solution offresh potable water and good quality householddetergent or proprietary cleaner using a pressure washerto entrap dust particles and spores. The maximum watertemperature should be 60°C with a maximum pressureof 1000lbs per square inch.

2. Wash: While surface is still wet, wash using a soft bristlebrush to remove any grease and dirt. Use a bucketcontaining a solution of fresh potable water and goodquality household detergent or proprietary cleaner.

3. Rinse: Rinse thoroughly to remove any loose dirt ordetergent foam using water spray at the lowest effectivepressure.

4. Disinfect: Apply a suitable disinfectant to all surfaces bylow-pressure spray with a water temperature of ≤10°C.Allow disinfectant to penetrate surface for sufficient time(according to manufacturer’s recommendations).

5. Final rinse: Wash off disinfectant using warm waterspray at the lowest effective pressure.

6. Dry: Use a food grade squeegee with flexible bladeto wipe surplus water and then use a vacuum systemto dry. Cloths and sponges should be avoided becauseof the potential contamination risk.

Cleaning Procedures:

When cleaning, the following points shouldbe noted:

1. Stronger concentrations of cleaners than thoserecommended can damage coating surfaces.

2. Always clean coated surfaces from top to bottom.

3. Over-cleaning or scrubbing can do more harmthan good.

4. Steam cleaning can cause damage if the coatingoverheats.

5. Water-spray must not be applied too close orperpendicular to the coating. At panel joints, thewater-spray should be directed at a downwards angleto avoid spraying pressurised water directly into thejoints. Old coatings should be treated with care.

6. For proprietary cleaners, follow manufacturer’srecommendations.


Panel Repair

Before performing any panel repairs, the surface must be cleaned as describedunder the “Cleaning” section and allowed to dry properly. Surface preparationis important and should be carried out by specialist contractors usingrecommended methods and approved maintenance paints.

Minor scuffs: Occasionally sheets are damaged duringhandling or erection or in use. It is not necessary to treat theaffected area unless the paint surface is visibly damaged.

Scratches: Where the coating has been scratched down tothe substrate, the affected area should be treated withsuitable touch-up paint in accordance with the paintcompany’s recommendations. It is important to ensure thatthe applied paint is no wider than the original scratch.To achieve this, the paint should be applied with an artist’sor child’s medium to fine paint brush. Touch-up paints are,of necessity, air drying; over the years they will changecolour differently from the original stoved coating. For thisreason, it is good practice to keep the applied area as smallas possible.

Dents: Where the external steel sheet of the panel hasbeen dented and the coating has not been scratched ordamaged, it is not necessary to treat the affected area.For aesthetic reasons, it may be a requirement to havethe affected areas repaired as described in the“Indentations” section.

Heavy dents or punctures: The affected areas canbe repaired as described in the “Indentations” section.This work should be carried out by specialist repaircompanies who are approved over-paint applicators andprovide guarantees for the repair work.

Over-painting: Surface preparation and over-paintingshould be carried out by specialist repair companiesusing approved maintenance paints. Cellulose based paintsshould not be used.

Indentations:1. Remove paint from damaged area using abrasive disc

and feather out areas. Blow off excess dust and wipedown with professional panel wipes.

2. Mix and apply multipurpose body filler according tomanufacturer’s recommendations to damaged area,avoiding surrounding paintwork. Panel profiles should bematched in the repair.

3. Finish filled area using abrasive disc and feather outedges. Blow off excess dust and wipe down withprofessional panel wipes.

4. Check repairs, and then apply primer according to paintcompany recommendations, keeping spray area to aminimum and avoiding hard edges. Dry in accordancewith paint company’s recommendations.

5. Apply suitable topcoat paint system and bake as perpaint company’s recommendations.
