Yes it is possible but not practical. Technically you can do it and you can put plastic laminate over plastic laminate. But the  layer your covering has to be super clean, abraded and all surfaces must be accessible. Edges and returns can be  more than a challenge. Any drop-ins likes sinks and cooktops have to come out and be reset after the new surface is in place. Results may be less than desirable.

 That being said, the cost of new laminate tops are one of the most inexpensive, so it would be better to just install new ones. You will be happier with the results.

No.  I don't think that is a good idera.  You are not going to be happy with result.  Hold off spending money doing what you are recommending until you have money to do it the right way.

We have an 11 Point Jobsite Cleanup Roster that all of our employees need to sign when they become employed by us. It lets them know of the expectation prior to starting work. It also holds them accountable if they do not cleanup the job site as required. We are very conscience of running a proffessional company, not only administratively but in all areas including production.

We always clean up after the job every day. If you leave things go then they build up over time and make a bigger mess. Carpet runners, plastic covering doors, and setting expectations for your employees/subcontractors is a must.
