What's the difference between caulking and silicone?

Caulk makes your surface airtight and watertight. Silicone sealants, on the other hand, remain flexible for years which make them ideal for areas that are prone to expansion and contraction. Silicone has strong binding properties that can be applied to almost any surface both indoors and outdoors.

Is clear silicone caulk better than white?

Clear caulk is good for sealing fixtures on tile or stone (such as in showers or around a kitchen sink). Use clear caulk where you do not plan to paint over caulk. White caulk is best used for sealing baseboards, trim, and siding. Use white caulk where you will be painting over the caulk.

People often ask, “Can you caulk over old caulk?” but it may be more important to ask, “Can you caulk over cracked caulk?” Generally, caulking over old caulk isn't recommended. Removing the old caulk and replacing it with a new bead of caulk instead usually creates a better seal.

What is the difference between latex and silicone caulk?

Latex or acrylic caulk with silicone added offers somewhat more moisture resistance than standard latex caulk. Thanks to the silicone, it's also a bit more flexible and durable. You can use this in the same places as standard latex caulk and for exposed (unpainted) applications that need only moderate waterproofing.

What is the most flexible caulk?

Synthetic rubber is a relatively new caulk category. It is perhaps the most flexible product on the market. Synthetic rubber cures clear and is ideal for exterior joints that typically expand and contract. It can be applied in adverse weather conditions (wet and cold) and stretches and recovers easily without breaking.

How do you fill gap between bathtub and wall?

If you have tile on the wall adjoining the tub, select a caulk that matches the color of the grout. If your gap is smaller than 1/8 inch in width, use regular caulk; fill gaps larger than 1/8 inch with a sanded caulk. Make sure the gap is clean and dry, then squeeze a thin, even bead of caulk into the space.
