My wife and I are remodeling a foreclosure we just purchased and have run into a problem. The original builder installed 3/8 engineered hardwood floors in the foyer, kitchen and half bath and he glued it to the plywood subfloor. We have been chipping away at it literally an inch at a time but it is still damaging the subfloor by pulling up some of it. I scored the hardwood the depth w/ a circular saw in a checker board pattern into roughly 2inch sections with one cut being down where the tongue and groove meet. I have used a heat gun on the cracks to loosen the glue which works but is very time consuming. I tried spraying mineral spirits in the cracks with less results.
My other options are to take out the subfloor too, or raise the rest of the floor up to the level of the old hardwood and install the new on top.
Does anyone know of a better way to get up the old hardwood? Thanks everyone!
