Can I apply a polyurethane finish on my laminate floors?

As a homeowner you may feel at times an inclination to paint your laminate floor with a polyurethane finish. Don't do it.  Resist this temptation. Resin in the laminate will prevent coatings like polyurethane from adhering properly to the laminate surface.

If you should find it necessary to paint these laminate surfaces with polyurethane paint, there are preparations you will find advisable to make. Be sure the floor is thoroughly cleaned of any dust, dirt, or debris before applying the paint. Also before painting, use a crack sealer and seal all cracks between your laminate floor boards.
