If you're interested in buying or selling dolls, or finding the value of a doll, use the MEMBER DIRECTORY to find a NADDA dealer in your area and to link to member web sites. Your local library or bookstore is also a good place to find a price guide on antique dolls.
The intent of the standard is to define reasonable lippage from one tile to another. When a tile is warped but within standards, all of the corners cannot be set in the plane of the adjoining tiles. Accordingly, the tolerance for variation from tile to tile includes the actual warpage of the tile.
The temperature of the tile and grout you are sealing must be between 50Â°F and 80Â°F (10Â°C to 26.6Â°C) at the time of application. Use grout sealer in a well-ventilated area. (If you are using an epoxy based sealer, then this will not be necessary.) Always wear gloves and use eye protection.
