Repainting Rusted steel for a water ride
Repainting Rusted steel for a water ride
(OP)
I am looking at a water ride at a theme park that has severely corroded parts of the steel structure. They want the repair process incospicuous and performed during the days the park is not opened (Mon thru Thu.).The SSPC website has all the info I need but I'm having trouble deciding which surface preperation procedure and which protective coating procedure to use. Is there a guide for selecting the appropriate repair procedure based on these circumstances, or does anyone have any suggestions? Thankyou
P.S. How do you feel about using rust reformers?

Do internet searches and you will come up with more.
Happy surfing.

Otherwise, you're talking about an SSPC SP-6, commercial blast cleaning.
Also, make sure you've got a sufficient factor of safety after the rust is considered. Once it's covered up, it will be forgotten, but your capacity will still be reduced.

As for the type of coating to use on these devices, moist-cured urethanes and epoxies work well. Surface prep should be near-white blast cleaning. Follow the manufacturer's recommendations on the coating.

1. Poly systems
2. Amine 2500
3. High Solids
4. Epoxy primer/urethane top coat
Recommended Proceedure
1.1 CLEANING TO REMOVE FOREIGN MATTER.
Remove foreign materials such as grease or dirt, from all surfaces prior to stripping paint or removing corrosion. Surfaces may be cleaned in accordance with SSPC SP-1.
1.2 PAINT STRIPPING (WHEN REQUIRED).
Residual paint and/or primer must be removed by mechanical or chemical treatment after initial surface cleaning. Mechanically clean using steel wire bushes, glass bead blasting, or honing processes.
1.3 CORROSION REMOVAL.
Abrasive blasting is the required (SSPC SP-10) to remove corrosion products.
Note: Proceed to Step 1.4 within 4 hours of blasting
1.4 PAINT. (Typical depending on system selected)
Top coating cannot be done in one coat.
Wash Prime surfaces per Anti-Corrosive Epoxy Primer MIL-P-23377D Type 1 Class 1 30Y94 US Paint S9001 Epoxy or equivalent specification to a thickness .6 to 1 Mil as specified.
545 Anti-Corrosive Epoxy Primer.D1001, 2-3 mils (50-75 microns) dry film thickness/2 coats.
Final topcoat application of US Paint Urethane Gray G1007 gloss or equivalent gray paint to a thickness 2.5-3mils(63-75microns) total dry film thickness/ 2 coats as specified by manufacture.
For steel applications we have have good luck with rust reformers (Phosphoric acids)
