We are replacing a vinyl floor with ceramic tile over a concrete slab. My concern is that when pulling up the vinyl in the powder room, there is a musty smell that indicates the slab contains moisture. Do we need to seal or treat the concrete before we put down the tile? There was a water leak in this room several years ago that was repaired but the vinyl wasn't pulled up at that time so the concrete never really dried out. The room is on the north side of the house so gets no direct sun. We're doing the same thing in the kitchen, but that concrete is dry.

see if now that the vinal is up whether the floor dries out, if not you probably need a moisture barrier - I think schutler.com make them maybe it is schulter.com

Moisture under tiles on concrete can cause adhesive failure.

"Concrete Floors - Remove all foreign matter by mechanical means. Floors must be free of efflorescence and excess moisture. To check moisture, test with a calcium chloride test kit, or by performing a mat test with a rubber-backed mat or plastic sheet taped to the surface." Retrieved 23 May 2002.

"Moisture Testing
Concrete floors, even with adequate curing time, can present an unacceptable moisture condition by allowing excessive amounts of moisture vapor to pass through to the surface. This can be a problem even on suspended concrete floors. All concrete floors should be tested for moisture emission rate by utilizing an anhydrous calcium chloride moisture test kit available from installation supplies and accessories distributors.
This quantitative method is very precise and must be conducted carefully, with strict attention to the test kit manufacturer's detailed instructions. Moisture emission rate is expressed in lbs/1000 sq ft/24 hours. Because the calcium chloride test for emission rate requires 3 days to conduct, proper installation planning is a must.
As a general guideline, an emission rate of 3 lbs (1.4 kg) or less is acceptable for most carpet. In the range from 3 lbs to 5 lbs (1.4 to 2.3 kg), carpet with porous backings can usually be installed successfully; but the risk of moisture-related problems increases. Since some floor covering products are less tolerant of moisture than others, always consult the individual manufacturer to determine the emission rate for specific products."
