Caulk is generally used to seal a variety of surfaces to make them water tight. It is important to note that not all caulks are suitable for all conditions. Choosing the correct caulk for the appropriate surface will determine how long it lasts and whether it works or not. If you intend to recaulk, it is important to know how to recaulk and the tell-tale signs you need to check out for.
Signs that you need to recaulk
In the case of your bathroom tub or shower, if you see that the caulk around it is getting a bit hard and brittle. You may also see that the caulking around your bathroom sink is discolored or stained from grime and soap scum. Any cracks in the caulking, especially on the window should not be ignored.
The presence of mildew on the surface of the sink which cannot be washed away or returns after being washed or some form of mold infestation under the sink is a sure sign that the surface in question needs a recaulk. The presence of moisture under the sink and yet there are no leaks in the fixtures or plumbing is also a warning sign. The sight of caulking pulling away from the sink or countertop should also inform you that you should plan on caulking again.

To recaulk your bathtub or shower, you will need Silicon caulk remover, utility knife and a new tube of caulk that is formulated for bathtubs. Remove all the existing caulk using a utility knife then pull it off. Spread the caulk remover and leave it for some time, then use a knife to dig out any remnants. Use alcohol to clean the bathtub edges, ensuring no mold or mildew remains. Apply some painters tape along the bathtub edge then cut the caulk tube and insert it into the caulk gun. Fill the tub with water, then starting from one corner, run a continuous bead along the edges of the bathtub, use a damp finger to smooth and spread the caulk. After 15 minutes, remove the painters tape and allow the caulk to set for 24 hours before using the bathtub.

Using a putty knife, scrap away all existing caulk and then wipe the sink using a wet rag and some chlorine bleach and let it dry completely. Cut the tip of the caulk tube and insert it into the caulking gun and carefully squeeze the handle to lay an even thin layer of caulk on the outer lip of the sink, use a wet finger to ensure thin but even coverage. Return the sink in its previous position; let it dry as per instructions before opening the valves again.
