谢谢。这个是某个论坛的帖子。似乎在欧洲不新鲜了,可在美国还是个新产品。 My company does installations for the Lumber Liquidators here in NYC. The " adhesive mat" the original poster mentioned is a new product called Elastilon. It is sold directly through the local stores, and costs about $2 a sq. ft. I've done a few installations on above grade concrete without any problems using it. Just make sure you follow these steps before installation. 1. Perform a Calcium Chloride moisture test of the concrete allowing no mre than 3lbs per 1,000 sq. ft. 2. Make sure the substrate is level within 1/8" over an 8' span 3. Use 6 mil poly moisture barrier installed underneath the Elastilon. 4. The home should be heated 2-3 days prior to installation at a temperature between 60-85 degrees, with a relative humidity between 40-65% 5. Allow the solid wood flooring product to acclimate for atleast 7 days in the area of installation. 6. Watch the videos below. Installation can be tricky without any prior knowledge.
