We have a 60+ yr.old home. We would like to put hardwood floors in our den. It is built on a concrete slab w/ no crawl space(originally 3 season).We took up the original 12×12 vinyl tiles (after tearing up our carpet) and are now left with nasty mastic on very rough old cement.There is a moisture and insulation problem. We would like to seal the cement (once mastic is gone)possibly add radiant heat, followed by hardwood. Any recommendation on removing mastic, leveling cement, sealing cement adding wood?How many inches would we be adding? We are replacing old windows and taking down walls to add insulation as we use this room all year. Our heat source is oil, forced hot h2o from iron radiator. Any help would be welcome.Thanks
its messy & slippery but it will work – not hazardous, either – environmentally friendly – ‘ green ‘ – no odor – just a pita impo,,, but it does WORK ! ! !
I would be suprised if what you have is mastic,since that is what is used to instal ceramic to a wall.If your ”floor glue ” is clear /yellow it’s clearspread,or multi-use floor glue.If it’s black it’s the old ”CUT BACK adhesive. There is a big differance.The cut back is no longer available but you would only see that usually under 9×9 tiles not 12×12’s But it is a hazard .Be aware some of the tiles way back in the day had trace amounts of asbestos in them.
