Afternoon people. Fitted some Westex silken velvet in a hotel and covered it with correct packexe carpet protector. Tested an offcut for 10 days and all looked good. Removed protector from landing and its left a pink tinge on carpet the exact width of carpet protector. Packexe says it’s nothing to do with them and when they inspected it you couldn’t see it if lights were off (it’s a bloody hotel landing the lights will be on the time) also they are saying if you brush the pile it disappears. Well I’ve tried that and it doesn’t. Anyone had any problems like this before? Any suggestions would be great?
