(title error: SINK SANK not SKINK)Hello, I laid a floating floor but when I stand on this specific area (see pictures) the floating floor sink about 2mm under the parquet skirting. The parquet skirtings are not glued yet so maybe I can insert a 2mm large plastic wedge under ? or any better idea ? I dont know how to fix this problem... Thank you in advance.pictures : https://ift.tt/2zXEnM2 via /r/DIY https://ift.tt/2LsLaC2
