I have taken up some old viinyl tiles which seem to have been put down with some sort of black (asphalt?) mastic that disolves in paint thinner. Under that is nice wooden floors. What is the best way to remove the mastic before refinishing the floor? It's still tacky so scraping or sanding will not do. I was thinking something similar to paint stripper where I put it on and then come back later to wipe it all off.
TIA
