Lifting snap-on laminate without damage is easy because the boards clip together and can be unclipped. No glue is used in the construction of the floor, unlike older flooring, which was typically glued in place. All you need is a pry bar and a few simple tools.
Take off the baseboards and lift the first row of laminate with the pry bar. Then insert the chisel under the first plank on the second row and hammer it to lift the board. Repeat this process, and you will be done in no time at all.
