If you've replaced a warped or damaged board, the new wood will not be the same shade as the rest of your deck. If you wish to stain immediately, use an opaque or semi-transparent stain to create a blended surface. An alternative to stains or sealers is applying a resurfacer or restoration product. These finishes are like a very thick paint. Applied with a brush or roller, they cover deck boards and do not show wood grain.
