Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to caulk [title] Use silicone caulk if you need a neutral-colored waterproof sealant. [step] There are two main types of caulk-silicone and acrylic latex. Silicone caulk is a completely waterproof and flexible sealant.

Ending1: Both types of caulk will not adhere to a latex painted surface and will stick to surfaces permanently made by the artist. Acrylic latex caulk is also designed to protect the surface from paint, oil, and water. Ending2: Its porous coating gives it a good finish and stays in place better than silicone caulk. Acrylic latex is best for use with surfaces where caulk can break and potentially cause an explosion, such as plasterboard or paint. Ending3: It will bond with a lot of different kinds of surfaces. Silicone is a good choice if you're caulking outdoors, or wet indoor spots like around shower stalls and bathtubs. Ending4: Canvas is also on the lower than canvas texture, so choose a caulk that covers the entire surface but not covers it entirely. Acrylic latex is usually mostly water-based and has a smooth finish.
