I wasn’t sure what topic to put this under. I am covering some old laminate on a office desk top. Do I just need to sand and clean to cover the existing laminate. 220 grit or what? Thanks Michael

Are you doing this in lieu of a repair? There are a number of repairs you can do, some fairly easily. More info on the problem, reason why you want something new down, if it’s just the look, that is fine

If you just want a different look I’d spend some times with 60/80 grit, and really rough it up. The base usually used for Formica is OSB or particle board, both are fairly rough. If you put it on something slick, it won’t adhere well. If it was a larger job, and the prep took long, or cost $$$$ to get done, or do, then it may be quicker, and cheaper to just pull off the existing tops, and start from scratch. If you buy the material, and do the fabrication, Formica is fairly inexpensive.

To remove the old laminate just lift a corner and squirt a bit of lacquer thinner between the laminate and substrate, it will dissolve the glue. It will probably take some time and fussing but should all come off fairly easily. Make sure you do this where there is good ventilation and no open flames around, lacquer thinner is explosively flammable!

If the old laminate is sound mean still well bonded to the substrate you can do as you suggest.

Changing to a new color, and didn’t teally want to buy some new mdf. So would it be better to remove the old laminate or just sand and install new?

That pretty your call depending on how much work you want to do. Just remember the dark color on the edge that shows with be twice as thick as before.
