Author Topic: Floor Resurfacing Bob Brown Expert Film Handler Posts: 146 From: Grand Rapids, MI Registered: Apr 2002 posted 07-01-2003 06:31 PM                        I am posting this for our IMAX Director in hopes of getting some opinions on this subject. The floor in our IMAX auditorium, which is painted, is in need of stripping and repainting. Other theatres in the building have been stripped and repainted, but using the pervious method, a great deal of paint dust resulted. What I am seeking is suggestions that you may have as to the best way to complete this project. We have a silver screen that can not be cleaned so preventing any dust from the floor sanding hitting the screen is of the highest priority! Any ideas?  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 07-01-2003 11:07 PM                    How important is it that the floor be painted. Is it worth the risk of damaging the screen and surrounding soundfold and seat cushions with the dust. For Imax you spend what 45 mins. for standard films and 2 or more hours for other films all this basically in the dark. If painting it is that important then I would scrape up the dead paint and roll the paint down on the floor.  |  IP: Logged Daryl C. W.

Otherwise you could try stipping the floor while wet, if possible.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 07-01-2003 11:39 PM                        Buy a lot of tarp.  |  IP: Logged Adam Martin I'm not even gonna point out the irony.

Might it be possible to remove the screen and store it (rolled up) in a clean air environment or sealed container while the work is being done?  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 07-02-2003 11:26 AM                        As Daryl notes, would it be possible to sand the finish of the floor while it is slightly wet? Would eliminate dust, but could raise other serious issues (e.g., electrical safety, slipping). Solvent strippers are usually not very effective on epoxy finishes, not to mention the fume hazard.  |  IP: Logged Gerard S.

Perhaps their long life would make them cost effective, as against repeated sanding and re-painting.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 07-02-2003 08:05 PM                     I've actually seen this being done in a factory where continuing production had to be in a relatively clean environment. The epoxy floor paint stripping was done in a semi-rigid tent-like thing with inflated ribs - "airshelter" or similar name. An exhaust fan blew the air inside through a flexible duct outside into a filter box that trapped some of the dust. The workers just picked up the "building" and moved it to the next spot when finished with the floor inside. Once the area being refinished was stripped the structure was to be deflated and removed and then the painting would be done in one go.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 07-03-2003 12:41 PM                        Dave, betcha that rig isn't going to come cheap, as neither will the positive pressure environment thing or even tons of tarp. I'd go with Gerard's suggestion; it's an elegant solution and probably the cleanest, not to mention inexpensive, and look at the variety of floor looks you can choose from! And I missed why it can't be just painted over?....cheaper still. Frank  |  IP: Logged
