Padco does work with acid cure. Hard to believe but you can do it. I no longer use the stuff because I want to be around to see any grandkids. I use a 9" sure-line on ALL finishes and use the wall to wall snowplow method on a 4' stick. On a "cut up" floor plan I simply put down a hard line along a joint if I must turn my back on that section for a while. Then when i get back to it and find it beginning to sticky up I cut along the hard line as sharp as possible without any overlap to start the next section where I previosly left off. It took a time or two to get good at it, even used tape the first few times on the joint to make razor sharp, but now noone can find where that "transition" took place.
Hope all that made sense.
I've done this with both water and OMU. Can't stand acid cure ven though I like the way it looks. I find 3 coats of Fabulon or Synteko OMU to be very comparable in appearance and in my opinion even more durable and less brittle.
hope that helps.
PS. I use the sure line based solely on cost. Padco is an inch wider but more expensive and besides, sureline has a cool turned up edge for easier snowplow. And I find the used pads keep well in an ammo can full of mineral spirits and can be squeegeed off for the next coat. I've gotten up to 10 uses with a single pad (but I was pushing it)
