Apply the contact cement solvent on the edge of the countertop nearest the bubble. Use a craft paintbrush to apply the solvent. Allow it to dissolve the contact cement according to the directions on the label.
Lift the edge of the laminate with a flexible putty knife once the solvent starts to work.
Apply more of the solvent underneath the laminate until you can lift up the laminate over the bubble area.
Allow the solvent to dry completely.
Use the brush that comes with the contact cement to apply it to the substrate underneath the laminate.
Place a small piece of wood or another object between the laminate and substrate to allow the contact cement to become tacky.
Wait until you can press a finger to the contact cement and can bring it away without any residue sticking to your finger.
Press the laminate down smoothly with your fingers to allow the contact cement to form a bond.
Use a rolling pin over the laminate to ensure the bond secures to the substrate.
