Paint manufacturers have recognized these problems and have come to the rescue with new solutions. But a word of advice: If your garage floor sees heavy water leakage, if it's badly cracked or if it's damp and slimy all summer, don't apply any coating. In those cases, you're better off simply keeping it as clean as you can and then calling it quits.
Determine needs vs wants: There is always a difference between what you WANT in your garage, and what you NEED. While you may want a high end entertainment complex, do you need it? Before you begin your project sit down and make a list of needs, and wants. By creating a prioritized list you keep yourself from overspending. Once you have your needs addressed, throw in a few wants.
You may have to drill holes through studs or through the top plate of walls to reroute wires. If so, be sure to center the holes on the stud. If the plastic-sheathed cables are too short to reach the next box when you reroute them, you can add a junction box and splice on a length of cable. The new box must be accessible either in the attic space or through a blank cover on the wall or ceiling.
For a garage-to-utility-room conversion, budget at least $6,000 for appliances, a utility sink, and space for sorting, folding and hanging laundry. A new utility room in place of an old garage brings convenience into your life, especially if you've spent years dragging loads of laundry up and down the stairs. This conversion will cost a bit more due to the addition of plumbing, but it'll be worth it.
