Stand- ing water, however, is a sign of trouble, and it must be removed before concrete finishing proceeds. There are several causes for excess water.

Sometimes the concrete is delivered with too much water, or the home- owner requests that water be added to the mix to increase its workability.

Poor-quality materials used in the concrete also can promote excess water rising to the surface. If you finish con- crete with the water present, the sur- face will be weak and prone to damage from wear and weather. To remove the a water, two people can drag a garden hose over it, or one person can use a rubber squeegee. With either method, be careful not to remove cement along with the water. After the excess water is removed, finishing can proceed as nor- mal. Cover the concrete with a plastic sheet to help it dry slowly.

I was careful to reset the clock afterward, too. Youd think Id get a nice thank-you, but the response after a test ride was a catalog of things gone wrong. The radio station presets were gone. The engine ran poorly. The compass in the overhead console pointed to some alternate dimension. Complaints trickled in for days. The rearview mirrors auto matic positions were wrong. The power seat memory was frazzled. At least the engine started to run better after a shop ping trip. For the next battery swap, I got smart. I used a 9-volt transistor radio bat tery to maintain the engine management computers learned defaults. You can plug a battery into the lighter provided the socket stays on even when the key is Off. Otherwise, youll need to use alligator clips to bridge into unswitched 12 volts somewhere. Be sure the doors are shut or the dome light is switched off.
