A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques.
In Scotland last year a group of coatings manufacturers estimated the coatings maintenance market was $2 Billion Dollars.
The estimation for coatings going over water jetting surfaces was 510%.
While all three are necessary for good coatings performance.
It is the last component, the removal of invisible contaminants and removal of detrital material, that demands water and which requires REFORM and CHANGE.
Everybody in this room has been raised with dry abrasive blasting and dry abrasive blast standards.
All of these coating manufacturers have put coatings over, hundreds of thousands, if not millions, of square feet of various substraates which have been cleaned with water jetting and wet abrasive blasting.
There is flash rusting involved in all of that stuff but it really does not affect the moisture cured polyurethane coatings supplied by Wasser.
Wayne Senick- Back to the text book- this is an article on the first job where there was a five year joint warranty between the coating manufacturer and the contractor.
It was pretty pleasing to see that before cleaning we were at 80-90 µg/cm2 of chloride but every case, every case, we got below 4 µg/cm2.
They were water jetting with sea water.
I come in and ask the question, both to the abrasive and water jetting people, about applications with vacuum attachment.
Lydia Frenzel- I have talked a lot to contractors about how much does it cost for WJ on a square foot basis.
