This is a defective product manufactured for years by Congoleum. We purchased our floor in 2008. In 2011 we filed several complaints with our county consumer board with ties to the NJ Attorney General's Office. We also had a visit from the independent inspector,sent by Mohawk.
The independent inspector (paid by Mohawk) was a complete farce!
Eventually Smart Carpet replaced this floor with a new one! ( no charge )
In a few months the same problem was occurring with our new floor! ( scratches or spotting showing base white ) Absolutely very ugly.
You must keep vigilant against Mohawk Congoleum. Our next step will be Small Claims Court
Review about: Congoleum Flooring.
Reason of review: Bad quality.
