Here is how I have dealt with a similar situation. The POs were covering up damage on oak hardwoods with area rugs. I am guessing that in addition to their petÂs accidents, they shampooed the area rug in place which further damaged the floors. We found out about the damage two hours before closing on the house during the final walk-through. This is a very temporary solution and is not the correct way to fix the damage; the experts on this board can advise you how to do that. Wash the floor on your hands and knees (or sitting on the floor using a small amount of water, MurphyÂs oil soap, scrub brushes, scrubbies, and old terry towels- whatever it takes to clean the floor. Do a small section at a time, and rinse with clear water using a clean towel and dry each section thoroughly as you go along. Be careful with the waterÂdonÂt pour it onÂyou donÂt want to cause more damage than is already there. This will take a long time as you will be crawling around the floor. With a damp sponge mop using water and vinegar, rinse again. Remember while you need the water to clean the floor, water also damages the floor. DonÂt let pooling water sit on the floor. Dry it with a towel. On the stains you can try several things to at least lighten the color of the damaged spots. I used a combo of lightly sanding and household bleach. The stains have not disappeared, but they are lighter and cleaner. Wait till the next day or several hours to be sure the floor is completely dry and temporarily fill in the spots where the poly is gone due to damage of pet stains, water and sanding/bleaching by judiciously using a small amount of wipe-on-poly. Wipe-on-poly is for furniture and is not recommended for floors, but a small amount can fill in and blend the areas where the floor poly is completely gone. After the poly is completely dry, use a shine product. I used Holloway House Quick Shine for about $9.00 (Orange Glow does not work). I have added a few throw rugs and the floor looks about 50% better and will get me buy until I can have the floors refinished.

You could try lifting the strips up using a 5 in 1 tool. Another option is to get a wood chisel, and split the wood carpet strips with the grain removing small slivers, once the strip is removed you should be able to scrape the glue off.

Thanks for the reply. It's concrete, but I doubt it would contain asbestos, but I'll check it out. I'm buying the Robbins Austin Plank at Lowes since it's 3 blocks from my house and the price was very competitive. They carry Bostik's Best, but I'll also check to see what Robbins recommends. About the removal of the Parquet....floor scrapper? Any prep needed before laying new flooring. The remaining sq. footage I'll be installing has carpeting so it's not so hard to remove. Thanks, Dave
