Welcome Welcome to the summer edition of our newsletter.

The last quarter has been fantastic for Paint Inspection Ltd and has seen our inspection team grow

yet again with new members joining us. Our newest team member is Keith Wagner an ICorr level

inspector based in the north of England. Keith has lots of experience and for the last 6 years has been

working primarily within the oil and gas industry, this has added a whole new dimension to the al-

ready large list of services we can oer our clients. Keith is currently working on projects, Beaumar-

is Pier (pictured above) and a large scale Gantry installation project on one of the UK’s main arteries.

The other new team member is John Elder. John has over years of experience in the industrial

coatings business and has worked for Paint Inspection Ltd on a freelance basis for over 6 months,

working on smaller projects, he recently accepted our oer to join the team full time and is now

working on high prole public projects that need to be delivered before the Olympics , John is

an ICorr level and will be sitting his level later this year. This shows our commitment to develop-

ment and that extra qualication will mean over % of the world’s ICorr level inspectors will beemployed by Paint Inspection Ltd.

Our ICATS training school also continues to grow from strength to strength with more agreements

signed to provide training to specialist authorities but more about that later in the newsletter.

Ian has had even more input into this edition with a follow on from last edition in the technical sec-

tion , this time he covers Amine Blush/Bloom and Blasting Cleaning Standards.

There is also news on our progress in gaining our ISO .

I will be covering our online client zone and will be providing a username and password so you can

look at examples of the type of reports we provide. This shows how we have embraced technology to

deliver excellent customer service

I hope you enjoy the newsletter and if you have any comments please don’t hesitate to contact us [email protected].

Technical Advice

Amine Blush/Bloom

what does it mean and how is the system

aected?

Our spring newsletter discussed the importance

of ambient conditions and continued monitor-

ing as we move into spring and summer.

One of the defects that can be caused by apply-

ing coatings outside of the specication is

Amine bloom which is happens when an epoxy

coating with curing amines is applied under low

temperature and/or high-humidity conditions,

a side eect of the curing reaction may appear

on the coating.

The cause: The curing agent (Polyamine) as

mentioned needs to cure out under the correct

temperatures and humidity and if this is com-

promised by either applying the coating out of

specication or if the ambient conditions

change during the curing process then the

amine will not continue to cure out which will

lead to side eects.

The side eect in appearance resembles thebloom on a grape that forms on the gloss lm,

this eect can appear as grey cloudiness, will

cause loss of gloss and dulling of colour, a

greasy waxy layer, or as white patches/spots.

More importantly is the poor overcoat ability

and intercoat adhesion which can be compro-

mised.

One of the key factors for the performance of a

coating system is good adhesion between the

substrate and each paint layer. If this is compro-

mised then the performance of the system will

be aected with potential coating failure and inturn the service life will not met.

Amine bloom can be removed, but this addstime and cost to the project.

Amine Bloom & Blast Cleaning

Preparation Preparation Preparation

Blast cleaning

In this edition we cover Blast cleaning and the im-

portance of good surface preparation.

Blast cleaning has been around for over years

and is the best form of surface preparation especial-

ly for high performance coatings.

Most coating manufacturers will provide a service

life of to years on systems which are applied

to a blast cleaned surface, although this service life

is dependent on good surface preparation being

achieved on the project.

A number of factors are key in the inspection pro-

cess of a blast cleaned surface; Surface cleanliness

ensuring the standard has been achieved along with

ensuring surface contaminates are removed i.e fromOil/Grease, blast dust to water soluble contaminates

such as chlorides and sulphates which are corrosion

accelerators. Surface prole has a special mention as

this provides the anchor for the coating system and

promotes good adhesion of the coating system.

Blasting standards in the ISO range refer to the

Swedish standards of SA, SA, SA½ and SA, these

blasting grades dier widely from a light blast to

remove poorly adhering paint, scale, rust etc to a

thorough blast cleaning of SA which is classed as white metal in the SSPC and NACE standards.

The most widely used standard is SA½ which

is mainly a site based blast standard of near

white metal nish with only slight stains in

the form of spots and stripes. This standard

is a subjective standard to assess on site even

when using the ISO visual standards refer-

ence book. Experienced Paint Inspectors will

make an assessment based on the type/age of

the steel, abrasive used and level of pitting

which all will aect the appearance of the

nish blast. Overall the cleanliness and pro-

le measurements detailing in an Inspection

Test plan are referenced against the speci-cation and Paint manufacturer’s recommen-

dations and these are the key indicators of

good surface preparation prior to applying a

coating system.

ICATS Training News

ISO 9001 Paint Inspection Ltd has been busy working towards gaining our Quality

Management Standard ISO 9001 Accreditation.

Our stage 1 assessment was very successful and we look forward with

condence to our Audit in July. We have learned some valuable lessonsin taking this step and, although we have always run a tight ship, it has

helped us make the best use of our resources and to ensure that the pro-

cedures we have in place provide our customers with the assurance that

they will receive a high quality, ecient and good value service from us,

every time.

Melissa Borthwick, Company Secretary

Our ICATS training is proving more popular than ever with courses being booked on a weekly basis.

We are pleased to be working alongside Nacro, within the Prison Service, providing ICATS training for oenders due for release. These candi-

dates will be working within their own grounds completing reparation works that not only improve their environment, but also gain them new

kills, experience within the industry and condence prior to their release. This sits well with our Company ethics regarding social responsibility

nd discrimination.Melissa Borthwick, Company Secretary

Q & A Are there dierences in the methods of preparation for Cast

Iron (CI) or Wrought Iron (WI) as compared to steel (i.e.

Various mechanical methods could cause damage to the CI

and probably need controls)?

Good question, the standards doesn’t show dierences

between CI and WI as they fall under the normal speci-

cation of ISO8501 due to their ferrous nature. Using

heavy impact tools on CI will as rightly noted cause

problems. Blast cleaning is always preferred and will

not cause problems like using needle guns or chisel

hammers etc.

What is the preferred preparation specication/standard for

over painting an existing coating system?

St3 (ISO BS EN 8501-1) is the best standard when patch

repairing a system. St3 is “very thorough hand and pow-

er tool cleaning: the surface shall be free from visible

oil, grease and dirt, and poorly adhering mill scale, rust,

paint coatings and foreign matter”. This is basically the

same St2 but there is a further requirement to give a

metallic sheen from the metallic substrate. It is alsoworth noting the importance of abrading the sound

coating which will provide a key for the new system,

along with preparing damaged paintwork back to a

feathered edge of sound paint.

Website Client Zone

The launch of our new online client area is proving extremely popular with our customers that use our inspection and surveying services.

The ability to look at structures and then view, print and download reports with such ease has essentially been the key to its success; also

the fact that reports can be accessed remotely proves a key benet for project managers that can’t always be onsite. Securely held on a

remote server these reports are always available and will be held for up to 5 years from date of completion. We currently believe we arethe only inspection company in the world that utilises this innovative of technology. Our inspection team particularly like the ease in

which reports can be formatted and that they have direct links into the standards which are utilised by our industry. This improvement

has meant that reports can be turned around quicker to our clients and reects in the lack of downtime for our inspection team increasing

productivity and delivering exceptional service.

We would like to invite all our customers to have a look at what the system looks like and have created a visitors area so a couple of exam-ple reports can be viewed. Access is easy just go to the home page of our website www.paint-inspection.co.uk and in client zone login usethe following:
