Stripping Polyurethane Varnish

Posted by stinkytiger (My Page) on

I have wooden doors (front and garage) which are covered in Minwax Clear Shield. I want to refinish these doors by stripping off the Minwax and applying Sikkens Cetol Marine.

Can someone recomend a good way to stripping 200 sq feet of this Minwax Clear shield?

I do not want to remove the doors, and have to contend with glass windows and rubber / plastic weather stripping. The doors are cedar, douglas fir, and some unidentified plywood.

I am willing to battle getting gassed by Methly Chloride, and risk fire (heat gun?), if I have to. But prefer to avoid this. Anyone have any advice as to how to go about this. I also do not really want to sand like crazy for the rest of my life.

If someone has a great heat gun technique, or some great chemical stripper / technique (saran wrap) I would love to hear about it.

warmest regards, Mike.

Someone just told me about Ready Strip which is peroxide based (not smelly or hazardous) but have not yet used it. Apparently there is problems with quality control - if it is an old batch then it doesn't work, has lost its potency. But new batch - said to work really well.
