Laminate is a convenient and inexpensive covering that gives wood particle board a realistic grain appearance. The only problem with laminate is that it wears off and scratches over time. Thankfully, you don't have to throw out your old laminate table if it is looking worn. Instead, replace the laminate top with a new one. All that is necessary are a few household tools and a free weekend.
Sand down the top surface of the table with an orbital sander and 60-grit sandpaper. Be sure and wear a mask to avoid breathing in the sawdust. Sand until you have removed the entire laminate covering on the tabletop.
Rub the top of the table down with a tack cloth to remove all the sawdust. You'll want the surface completely clean so that the new laminate will properly adhere.
Measure and test lay the laminate over the tabletop. It's all right if it slightly hangs over the edges, as you can cut away the excess later. The key is to make sure that there are no bare particleboard surface showing.
Remove the covering on the laminate adhesive and place the laminate on the table.
Run a hot iron over the laminate to trigger the glue to adhere.
Run a roller over the entire table to press out any bubbles and ensure the best adherence. If you don't want to spend the money on a hand roller, you can use a clean rolling pin. Let the adhesive cool and dry, then trim away any excess laminate.
