- Q.Is laminating over existing
plastic laminate an acceptable practice? If so, what is
the best procedure?
responds: It is possible to add a second layer
of laminate, though it’s always best if
you can remove the existing laminate and get down
to a clean substrate. Unfortunately,
there’s really no good way to get old
laminate off unless it’s loose to begin
with. If so, by using a torch and a putty knife,
you may be able to remove what’s there.
Don’t ever apply a second layer over loose
If the first layer is well adhered, scuff the
surface with a belt sander and an 80- or 100-grit
belt. The key is to break the slick surface, since
most glues will not stick well to slick, nonporous
surfaces. After scuffing the surface, wipe it with
a solvent like mineral spirits or paint thinner.
This helps the glue to "wet out" — meaning
that the glue will spread well instead of beading
up on the surface. After wiping the counter clean
and dry, apply the laminate as you usually
