after abatement

			This is the 905 almost one month to the day after the asbestos abatement was completed. As you can see rust is beginning to bleed through the latex lock-down coat applied by the abatement company. Our situation is that we intend to replace the asbestos that was removed with a filler material. Then we will cover this filler with 16 or 18 gauge sheeting. We don't want to apply that filler and sheeting until the locomotive has made its move. Moving is governed by the rains and has to wait until Kiddyland next door is shut down for the season. It will be September 2008 before the move happens. And we don't want to spend a mint treating a section that will never be seen once the sheeting is applied, but we do want to treat the rust. And, of course, we don't want this to be an eyesore for the next six months. Our primary method of rust treatment for the boiler section previously encapsulated with asbestos is to use phosphoric acid. It is the primary chemical in these rust converter paints. After the acid treatment changes the rust to a paintable surface, we will prime and paint a flat black. This should make it look more like a locomotive and less like a rust pile. The only problem is getting past the latex paint sprayed on as a asbestos lock-down treatment. Yes, we realize it can be done. Paint stripper chemicals would appear to be the easiest. Because of the really rough surface, it is the less effective method. It appears from the tests below that we can simply acid treat over the latex and get a desired result.



			The phosphoric acid appears to soak through the latex paint, but doesn't remove the paint. Wear protective gear, goggles, gloves and I suggest a respirator. Also, this acid does not dry in a couple of hours or even overnight. So plan accordingly. Washing up with water works great.



			Results after the first work session to repaint the boiler section: those sections already acidized are being primed with XIM white primer. This is a very good primer. It will stick to about anything including glass and galvanized steel.....expensive also......... $30 a gallon. Then we are going on with a flat black. This is only a temporary paint job. The boiler section will be covered with an replacement filler for the asbestos then covered with galvanized sheeting. Sometime in 2009, everything will be sandblasted and repainted.
