Once the joint is completely dry to the touch, you are ready to proceed with the second half of the re-caulking expedition. The first thing you want to do is fill your bathtub with water. This will serve to force your bathtub away from the wall, making the eventual caulking assignment that much easier to do. Once the bathtub has been filled with water, you need to get into the bathtub for the best position possible. It is recommended that you wear high boots during this period of time so that you can stand in the water without being very uncomfortable as a result. Some people also caulk naked to avoid that uncomfortable feeling, so the choice is completely up to you as to which particular pathway you would like to follow.

Make sure that the caulk you use is not only resistant to mold, but was actually meant for use in the bathroom shower area. The reason this is important is that the chemical composition is different and the caulk will last longer and be more effective if you use a brand that was specifically made for use in the bathtub. Going smoothly and steadily, apply a layer of the caulk across the joint, smoothing it into the joint with one of your fingers once the layer has been applied. Once you have applied and smoothed out the layer, wait at least a day (and maybe longer) before you use the bathtub to let the caulk set completely. Only after the caulk is completely dry and devoid of movement to the touch should you start showering in that bathtub.

before you actually go ahead and do the caulking. Many experts believe that this is the single largest mistake made by the average do-it-yourself individual and it is a mistake that could force you to re-re-caulk again a lot sooner than you otherwise would have had to if you had caulked the expanded joint with the help of the bathtub full of water.

If you want to make your caulk job look impressive and professional, invest in a caulk-right tool at the same time that you buy your caulk-away tool from the hardware store. This is a tool that is really nothing more than a glorified spatula, but it will allow you to smooth the caulk over just as you would icing on a cake. The end result will look a lot better and the tool itself does not cost that much to buy.
