Once the joint design has been completed, a material with required properties must be
chosen. Typical properties of each class of sealant are summarized in Table 5.3. Preformed
seals are considered in Chap. 6 on expansion joints.

Acrylic-based sealants are factory-mixed, one-component materials polymerized from
acrylic acid. These are not used on joints subject to high movement because of their rela-

acrylic-based waterproof coatings. Acrylic materials are available in brushable or trowel
