Sealants

Re-mov/DSR5 works on a lot of products and materials! See list here.

Sealants are usually made of synthetic elastomeric materials. These are materials, such as natural or synthetic rubber, that are able to resume their original shape after having been somehow deformed. They are used in joints between stone or metal, at expansion joints in masonry, around window and door openings, and for horizontal surface joints, among many other applications.

Sealants may be single-component or multicomponent. They generally display good adhesion, cohesion, elasticity and good weathering characteristics. Common types include silicone, polyurethane, polysulfide, acrylic, latex and butyl-based sealants.

Sealants from Amazon:

Polysulfide sealants were the first widely used elastomeric sealant. These are generally used for joints submerged in liquids such as in swimming pools, fountains, cooling towers, fuel and chemical storage tanks, wastewater treatment and petrochemical plants.

Developed in the 1950s by Dow Corning, silicone based sealants became very popular. From seals around bathtubs and showers to attaching heat-resistant tiles to the Space Shuttle, silicone has many diverse applications.

Butyl sealant or caulking is made from synthetic rubber. It's impermeable to air and water and used anywhere an airtight rubber seal is needed. It can be applied to concrete, cinder block, brick, and stone. It's good for use on gutters, flashing, chimneys, and aluminum siding, for example. Due to it's bonding ability in wet conditions it is a good choice for use underground and on roofs. Isobutyl-based sealants are typically used for glazing joints.

Acrylic sealants are used in small-scale construction where there is limited movement between the parts. The term "acrylic" is used for products that contain a substance derived from acrylic acid. Acrylic sealants can be used on plastics, wood, concrete and metal - both indoors and outdoors. They are often used on driveways and to seal airport runways making them resistant to chemicals and weathering.

Sealant removal with Re-mov:

Polyurethane sealants are generally used in applications requiring resistance to abrasion and cracking due to joint movement. Polyurethane sealants can be pressed, layered, sprayed, or brushed onto joints but is usually applied with a caulking gun. It is also often used as a heavy-duty adhesive, as well as a protective coating.

Latex sealants are used in light building and residential construction. Acrylic latex caulk is water-soluble when wet, and can be painted over. It is inexpensive and a serves as a good general-purpose caulking. It is much easier than silicone caulk to apply and remove when needed. Acrylic latex includes acrylic polymers, water, latex, and fillers. This combination of ingredients is particularly good at bonding with rough or porous surfaces such as masonry, wood, drywall, and plaster. It is better used for filling small gaps in wood finishing as opposed to large cracks in walls.
