Caulk is a must for home projects; it seals and fills joints, for example, around bathtubs or counters. Caulk is most commonly made of silicone, latex, or acrylic. Caulk can also come with or without sand. Sand is sometimes added to caulk to make it thicker, and sanded caulk is recommended to fill a larger than 1/8 inch thick joint.
