Caulk and Caulk Sealant

• Caulk – Caulk or caulking is a moldable material that seals joints or seams to prevent leakage in piping and other such structures. It fills in gaps throughout the structure. The oldest form of caulk was based on a fibrous material. Caulk is ideal for areas with minimal expansion and contraction, as it becomes quite rigid when dry.
• Caulk Sealant – Caulk sealants are made of flexible material, most commonly Silicone. The main difference between caulk and sealant is elasticity. Sealants are ideal for areas that may expand or contract. Sealants can be hard or soft, visible, or invisible when dried.
• Benefit of Caulk – Buildings age with time. Along with aging, some gaps may appear in areas from time to time. That is where caulk comes in. It can seal those gaps, sometimes without even being noticed. Caulk may also be used in areas where you want to seal off against moisture. Caulk keeps moisture and air outside, where it belongs.
• Mold Resistance – First and foremost, caulk is waterproof and moisture resistant. For this reason, it prevents the growth of mold.
• Mildew Resistance – As for Mildew, caulk contains an EPA approved Biocide called ‘Mildewcide’ that prohibits the growth of mildew for a certain amount of time.

Types of Mildew-Resistant Caulk

• Acrylic Caulk – Acrylic caulk is the best option for caulking of residential buildings. It is particularly excellent in cases of repeated mold infestation, such as bathrooms or other heavy moisture areas. It is ideal for caulking sinks, tubs, and kitchen countertops. It is easy to use and adheres well to surfaces, as well as offers a smooth painting surface.
• Types of Acrylic Caulk – Acrylic caulk comes in two varieties, acrylic latex caulk and blended acrylic caulk. Acrylic latex caulk is water-based, easy to use, and even easier to clean. Whereas, blended acrylic caulk is partially siliconized, very durable against moisture seepage and excellent for areas where moisture penetration is a recurring problem.
• Silicone Caulk – Silicone caulk offers the highest resistance to mold as they are made of fully synthetic material. It is the choice of professionals for sealing wet and tricky surfaces such as ceramic tiles, glass edges, and porcelain. It adheres to surfaces much better than acrylic caulk. It does not crack and is easy to remove from any mold spores and repatch.
• Silicone Caulk Cure – There are two ways to cure silicone caulk. The first way is Neutral caulk, which is ideal for wood and metal surfaces. The other way is Acid cure, which is used for non-porous surfaces such as glass and glazed tiles. But keep in mind that acid cure silicone can corrode metal and may also cause damage to plastic materials.
