The term adhesives describe a variety of products that are used to attach one surface to another.
Construction adhesives are used to attach paneling and drywall to framing, install subflooring, and attach ceiling tiles. Special types of adhesives are used to install ceramic tiles, floor coverings, and carpeting.
There are also many types of glues used in a household or workshop environment.
Different glues have different characteristics. Some are quick drying, others are slow. Some are waterproof; some are not. Some must be dried under pressure, etc. Therefore, it is important for the carpenter to know what adhesive to use in a particular situation.
Care to be Taken While Working With Adhesives
At some point in your career, knowing what adhesive to use in a given situation will become second nature. In the meantime, ask a professional such as a building supply specialist.
• Always read the instructions on the label before using any adhesive.
• New products are being introduced all the time; so it is important to keep up with what is going on in the industry.
• Most adhesives are made from chemicals, some of which are toxic and/or flammable. Read and follow the safety instructions on the label and check the material safety data sheet (MSDS). The MSDS for any toxic or flammable substance must be available at the job site.
• Work with adhesives in a well-ventilated area away from open flames.
• Wear a face mask and eye protection.
Glues, Construction Adhesives, and Mastics
Glues are used in laminated construction such as arches, curved members, and building beams, and in the construction of cabinets and millwork. Carpenters may carry a plastic bottle of liquid glue in their toolboxes for making some interior trim joints or cabinet work on the job. Glues come in two forms: liquid or dry. The dry forms are mixed into a liquid on the job. Some glues come in two or more liquid forms.
Some of the most common types of glue a carpenter might use are:
• Animal or hide glue
• Polyvinyl or white glue
• Casein glue
• Urea formaldehyde or plastic resin glue
• Resorcinol resin or waterproof glue
• Contact cement
B. Construction Adhesives:
Construction adhesives are available for many types of heavy-duty construction uses. They are made for specific applications such as installing paneling, structural decking, and drywall.
In addition to providing strong bonding between materials, construction adhesives offer such advantages as sound deadening and the bonding of dissimilar materials such as wood, gypsum, glass, metal, and concrete.
There are several types of adhesives for fastening sheet materials to framing members. They include the following:
• Construction adhesive
• Neoprene adhesive
• Contact cement
• Drywall adhesive
• Instant-bond glue
Mastics are generally used to apply floor coverings, roofing materials, ceramic tiles, or wall paneling. Most mastics have a synthetic rubber or latex base. Some are thick pastes and can be used where moisture is not present. Others are waterproof and can be used in bathrooms, kitchens, and laundries, or in direct contact with concrete.
