How to Fix Bubbling in Laminate Countertops

There are two kinds of bubbling that can happen with laminate, and only one of them is reparable. If a hot object like a frying pan was placed on the laminate and it created small blisters in the surface, there is no cure besides replacing the laminate or the whole countertop. If the laminate has large, raised bubbles or lifted areas in the center or around the edges, you can likely fix the problem without a trip to the hardware store.

Step 1

Plug in a household iron as close to the countertop as possible, or use a heavy-duty extension cord that is long enough for you to maneuver the iron around the damaged area.

Step 2

Set the iron to a medium-high temperature.

Step 3

Fold a bath towel in half and place it over the raised or bubbled area.

Step 4

Place the iron on the towel, and move it back and forth with firm pressure to heat the glue under the laminate. Don't hold the iron in one place, which can melt the laminate or cause widespread bubbling or lifting.

Step 5

Lift the towel periodically to determine whether the glue has reactivated and the laminate is sticking.

Step 6

Remove the iron and the towel once the laminate has adhered back to the countertop.

Step 7

Set several large, flat, heavy objects, such as books, on the heated area to hold the laminate down until the glue has cooled.
