Typical PC conditions:

- Airless spray- Graco King pump, 45:1 or 60:1- input pressures of ~80psi, so fluid pressures around 3500psi plus- 13’40o or 15’40o tip typical for most work- DFT’s of twice target usually achieved in webs- steelwork sprayed in unheated shop, often moved outside after 1 to 2 hours in any weather- multi-coat systems only done by certain applicators due to lay-out space

• The Corrosion ProcessAt the Anode (-) : Fe Fe++ + 2e

(Solid metal dissolves into solution)

At the Cathode (+) : 4Fe + 302 + 2H2O = 2Fe2O3H2O

(Dissolved metal reacts to form rust)

Why Paint Structural Steel?

• The Corrosion Process• Millscale

Intact, fresh millscale

Millscale beginning to crack

Advanced millscale detachment

Millscale• Chemically active layer

• WILL detach and form corrosion, in the presence of moisture and oxygen

• If painted over, detachment will be slowed but NOT stopped

• Removal by blast cleaning, followed by protective coating, advised

Hand Cleaning

• The use of hand or power tools such as:

– wire brush– scraper– power wire brush– chipping hammer– grinder/abrasive paper or sander

Hand Cleaning• Cannot remove tight millscale• Not recommended for new steelwork

• Swedish Standard SIS SS 05 59 00 (Edition 3 -1988) (EN ISO 8501-1: 1988) :

– St2 - ‘thorough hand and power tool cleaning’– St3 - ‘very thorough hand and power tool

cleaning’• (see also SSPC - SP2 and SP3)

Standard of Cleanliness

Different rust grades of steel:

A – intact millscale (rare, hard to blast)B – millscale partly weathered (usual)C – millscale all weathered off (sometimes)D – rusted and pitted (common in

maintenance)

Standard of Cleanliness• Usually called ‘Quality (or Standard) of

Blast’

– Swedish Standard SIS SS 05 59 00 (Edition 3 -1988) (EN ISO 8501-1: 1988) :

– Sa1 - ‘light blast cleaning’– Sa2 - ‘thorough blast cleaning’– Sa2½ - ‘very thorough blast cleaning’– Sa3 - ‘blast cleaning to visually cleaned steel’


• See also BS 7079 (Part A1:1989) and American SSPC (Steel Structures Painting Council):

– Sa2½ - ‘near white metal’– Sa3 - ‘white metal’– (Sa2 - ‘commercial blast)’


Note:

You will never get a grade D surface to the same Sa2½ as a grade A or B surface.

Surface Profile

• Also called ‘Surface Roughness’

• For any specified standard of blast cleaning, many different profiles are possible

• Depends on the type of abrasive used

Round Shot Angular Grit

Profile required for most paints:

• 50 - 75 microns, slightly angular

• Zinc Silicates: – 75 microns - angular (‘sharp’)

– High thickness, offshore splashzone: – 100 microns - very angular

Water/Hydro Blasting

• Usually for maintenance, not new construction


• Water Blasting (‘Wet blasting’): use of water, mixed with air and abrasive

– Keeps down dust– Reduces spark hazard– Washes steel of salts in corrosion profile– Standards: as dry blasting– Inhibitor may be used to prevent flash rusting– Abrasive gives profile


• Hydro Blasting: use of water alone, at ‘ultra high pressures’

– No abrasive used, no site clean-up required, no dust (also no profile)

– No spark hazard– Washes steel of salts in corrosion profile– Standards: as dry blasting, but informal

‘HB2½’ being used

Basic Components of Paint

• 3 principle components:

• Resin

• Pigment

• Solvent

Common ‘Convertible’ Resins

• Epoxy– epoxy resin+amine/polyamide (base+curing agent)

• Alkyd– alkyd resin+oxygen from air (single pack)

• Polyurethane– isocyanate resin+polyalcohol (base+curing agent)

• Moisture Cured Urethane– isocyanate resin+moisture from air(single pack)

Common ‘Non-convertible’Resins

• Chlorinated Rubber

• Acrylated Rubber

• Vinyl

Resin Properties - Epoxy• “Pro’s”:

– Hard– Chemical/solvent resistant– High film builds/more protection in fewer coats

• “Con’s”:– Two pack– Minimum curing temperature/hardening time– ‘Chalk’ on exterior exposure– Health and Safety - skin sensitisation

Resin Properties - Epoxy• Chalking:

Basic Components of Paint

• 3 principle components:

• Resin

• Pigment

• Solvent

Paint Pigments• Colouring pigments:

– Titanium Dioxide (white)– Iron oxides (brick red and others)

• Fillers and extenders• Anti-corrosive pigments:

– Zinc metal (‘dust’)– Zinc Phosphate– MIO (micaceous iron oxide)

• Coatings often classified by pigment -– “a coat of zinc phosphate ...”

• The Corrosion ProcessAt the Anode (-) : Fe Fe++ + 2e

(Solid metal dissolves into solution)

At the Cathode (+) : 4Fe + 302 + 2H2O = 2Fe2O3H2O

Dry Film Thickness

– Specify DFT required

– No need to specify wet film thickness -this will be determined by required DFT and volume solids

Dry Film Thickness– Correct DFT is crucial– Too thin or too thick can both cause

problems - “minimum” DFT’s can be fatal!

– Success of system:– Surface Preparation - 60%– DFT - 25%– Choice of paint type - 15%

Dry Film Thickness -Measurement


– Gauge can be calibrated in two main ways:• ‘nominal’• ‘over-the-peaks’


Smooth steel plate - ‘nominal’ calibration


Nominal: set gauge on smooth steel reference plate (draft CEN standard)

Zerodft


Over-the-peaks: set gauge on blast-cleaned reference plate

Zerodft


– Over-the-peaks ‘loses’ around 20-30 microns on a typical blast profile

– Over-the-peaks DFT’s cause increase in costs and can be highly damaging to coating performance


– All paint manufacturer’s recommended DFT’s are ‘nominal’

– BS 5493, NBS, CIRIA and ISO 12944 recommend ‘nominal’

– New standard ISO/FDIS 2808 – “Paints and Varnishes – Detemination of film thickness” due out ~Feb 2007 says calibrate on smooth steel.

DFT - Advice to Specifiers

Always specify:

“nominal dft’s, measured in accordance with paint manufacturer’s

recommendations”

– Volume Solids



‘Life to First Maintenance’

• ROUGH estimate of coating lifetime

• Does not mean coating has to be replaced after this period

• Most useful as a relative measure to compare different systems

• ‘Maintenance’ could be simply for decorative reasons

• Corus Group (formerly British Steel)

• CIRIA

• ISO 12944

Guides for Specifiers - BS5493

• BS 5493 : 1977 -

• “Code of Practice for protective coating of iron and steel structures against corrosion”


• Defines environments:– Exterior/interior– Inland/coastal– Polluted/non-polluted– Dry/wet– Water immersion– Seawater splashzone/immersed


Specifies PRODUCTS & SYSTEMS:e.g. System SK3:

Epoxy primer KP1A - 70umEpoxy intermediate KP2B – 100umPU Finish FP1C – 100umTotal 270um

EPA - The Environmental Protection Act

• Environmental Protection Act 1990, Part 1

– Wide ranging legislation, not just paint– Details for different areas of activity given in

‘Process Guidance Notes’ (PG’s)– Changing situation - subject to review


• For PC-type paints: ‘PG6/23’

– “Secretary of State’s Guidance -Coating of Metal and Plastics”

– PG6/23(97) (revision at March 1997) gives VOC figures for paints effective 1st April 1998


• VOC = ‘Volatile Organic Compound’

i.e. SOLVENTS


• Restrictions apply to ‘manufacturing processes’ (fixed shop, regular use)

• They do not apply to exterior use (site coats, maintenance painting)


• Small users exempt (less than approximately 200lts/week of paint, or 30tns of steel/week)

• Users have a choice under EPA:– Reduce VOC emissions by vapour

recovery/filtration technology (£££)– Use ‘compliant’ coatings (no cost)


• ‘Compliant’ Coatings:

– contain prescribed levels of VOC’s


• Compliant Coating limits in force from 1st April 1998 (PG6/23-clause 20[d]) [now dead]:

– Blast/etch/wash primers - 780gm/lt– Primer/undercoats - 250gm/lt– Top coats - 420gm/lt– (Heat resisting and intumescent have separate limits)


• Effect of EPA on paints:

– increase of volume solids to technical limits

– many widely used coatings obsolete

VOC Regulations for ‘building’ coatings2004/42/EC

• Former ‘EPA’ solvent regs (‘compliant coatings’) replaced in Oct 2005 with ‘SED’

• Applied to ‘fixed’ installations using ~>200lts per week of paint

• EPA did NOT apply to site work, building maintenance, bridges, etc.


• New regs for ‘buildings’ and vehicle refinishing (Nov 2005)

• Effective 1st Jan 2007, second phase 1st Jan 2010 (vehicle refinish – 2007 only)

• Brings paints used for maintenance into VOC regs for the first time

• CEPE defines a ‘building’ as something with walls and a roof (a bridge would be a ‘structure’)


• ‘The Volatile Organic Compounds in Paints, Varnishes and Vehicle Refinishing Products Regulations 2005’

• One common name in use is: ‘VOC product directive’

• Other reference seen is 2004/42/EC, the European Directive which this product directive is implementing


• Defines 12 categories for building paints:

– a – interior walls (matt)

– b – interior walls (glossy)

– c – exterior wall coatings (masonry, brick, etc.)


• Cont’d:

– d – interior/exterior trim and cladding paints for wood, metal or plastic

– e – interior/exterior trim varnishes and woodstains –transparent or semi-transparent

– f – minimal build woodstains

– g – primers – with sealing or blocking properties



– h – binding primers – to stabilise loose substrates or protect wood

– i – one pack performance coatings – special applications such as:

• For plastics

• Primers for steel, zinc, aluminium

• Anticorrosion finishes

• FLOOR COATINGS

• Anti-graffiti, flame retardant, hygiene



– j – two pack performance coatings – as (i) but 2 pack

– k – multicoloured coatings – multicoloured finishes

– l – decorative effect coatings – treated with tools during drying period


– From Jan 2007 (then Jan 2010), all paints made for the ‘buildings’ market must have less than the defined VOC content

– Paint MADE before Jan 2007 can be sold until 31st

Dec 2007 irrespective

– Cans (made after Jan 07) must also be LABELLED, with:

• VOC limit value and date

• VOC content of product in ready to use form

• 2004/42/11A(j)(500g/l2010)419g/l

Compliant Systems -Water Based

• Available but rarely used for new construction

• Very temperature, humidity and ventilation sensitive (ideal: 15°C, 65%RH, good air movement)

• Ideally needs purpose-built plant

• Steel surface cleanliness crucial (weld flux, oil)
