New Painting Technology
We typically would sandblast steel down to a shiny surface or close to and paint with a primer and then 3-5 mil of enamel paint.
We just did a floating conveyor which we used a MARINE grade paint (very expensive) but, no peeling.
...................
OUr shops have just recently started using an interesting new technology which is a "SPRAY ON METAL PREP" which is very easy, very quick, very UNLABOUR intensive and lowers costs substansially vs SANDBLASTING.
>>>>>>>>>>
We just did a couple of jobs with this vs sandblasting, moving equipment around, etc, etc.....and on one job saved 100 hrs of labour and on another job saved 150 hours of labour.
THE RESULTS when finished were just as good as with sandblasting.
If you keep your steel undercover INSIDE from elements of course this nicely reduces PREP TIMES.....and mfg costs. ■
Re: Paint Job
Can you tell me what brand of Spray on metal prep it is???
Any specs or product name so that i can buy a trial pack for use ■
Paint Etc.
You should try Rust Oleum It works very well in my opinion. ■
More Paint Information
For regular Painting Procedure
Sandblast is recommend but not necessary
When sandblasing is not done use metal prep to wash down or wipe down equipment
to degrease metal
Then apply Intergard 345 epoxy one coat until all areas are covered usually in the result you
get 4-6 mills of coverage.
For data specs please look at the following data sheets attachment:
The price $48.40CAD/gallon.

Greetings Sandeep,
I am unure as to a proper answer as you have not specified as to
whether it is the interior or exterior of the wet screen.
Many people use the "Rust Oleum" paint brand for metal
protection and it is a matter of personal preference as to what
one wishes to use as minerals will wear away paint jobs
regardless of the quality of paint as in most cases it is a cosmetic
application and is soon gone having been worn away while it- the
screen is operating.
Are you screening drilling mud with your application?, If so how
many desilting cones are you using if any? ■
Paint Job
Dear Sir,
I would like to know the correct paint to be used for protecting dewatering screens. Also would like to know a very durable painting method in the absense of a sand blasting unit.
What should be the primer used and what kind of surface preparation has to be followed.
We have been using PU paints and they tend to peel off as their bonding is not as high.
I need someone to give me a good painting solution right from surface preparation to the final coat. ■
