Deck 25: Bonding Agents, Sealers, and Sealants

Question 1

____ are moisture-resistant, but not used where they will be exposed to moist conditions.

A) Thermoplastic adhesives
B) Thermosetting adhesives
C) Melamine adhesives
D) Resorcinol resin adhesives

Answer 1

A

Question 2

Describe the uses of clear silicone dampproof liquids and how they are applied.

Answer 2

Clear silicone dampproof liquids are widely used on exterior concrete, masonry, and wood surfaces. They are not a surface coating but penetrate a material, carrying solids into its pores. They do not color a wall but do reduce efflorescence. They can be applied with a brush, roller, or spray.

Question 3

How are epoxies used?

Answer 3

Epoxies are used to provide a waterproof coating. They are often employed to seal floors in areas where moisture or chemicals exist, such as in food processing and industrial applications. Other uses include floors around swimming pools, decks, showers, restrooms, loading docks, and on stair treads. When mixed with an aggregate, such as emery, epoxies provide a textured, slip-resistant surface available in a variety of formulations.

Question 4

____ waterproofing sheets are frequently used for projects in which waterproofing must be of uncompromised security.

A) Lead
B) Cement-based
C) Bentonite clay
D) Chlorinated polyethylene

Question 5

What are the forces that waterproofing must be able to resist?

Question 6

____ membranes are sheet products made by laminating two or more waterproofing materials.

A) Sheet
B) Adjoining
C) Cement
D) Composite

Question 7

____ sealers come in liquid form for use on brick, concrete block, stucco, cement plaster, and concrete.

A) Asphalt driveway
B) Epoxy
C) Acrylic
D) Silicone

Question 8

Question 17

A form of liquid waterproofing uses a(n) ____ that reacts with soluble calcium in concrete to form a glass gel in the microscopic pores.

A) acrylic copolymer
B) polyurethane rubber
C) silicone dampproof liquid
D) silicate liquid gel
