When buying a house, be sure to change the locks immediately. There is no telling how many people had access to the previous owner's keys. When renting, be sure to ask about the landlord's key-control policies.
If you are gluing veneer to a wood surface, you can use an old clothes iron to help. First use a sponge to wet the face of the veneer so that it won’t curl. Next, apply a thin film of glue to both the surface and the underside of the veneer. Then, when the veneer is dry to the touch, use the clothes iron at a high setting to secure the veneer in place.
