Repairing Laminate Bathroom Countertops
If you have laminate bathroom countertops, there is a good chance that they will need to be repaired at some point. Water could damage the counter, or something hard could dent it. If the damage is too bad, you may have to replace the counter; however, for smaller problems you should follow these repair suggestions.
Laminate is comprised of multiple layers; therefore, the layers can come apart over time. Sometimes the top layer will come loose and bubble up. If that happens, you may be able to reheat the adhesive with a blow dryer or an iron and reactive the adhesive. Then you may be able to press the top layer back into it. If the old adhesive will not work, you can also apply contact cement. Use a rolling pin to remove air pockets from the top layer.
If the laminate surface is chipped or dented, you may be able to fill the hole. You can buy a laminate filler at many home improvement stores. You must match the color of the laminate and fill the hole before allowing it to dry.
