impical Sealant Installation Procedure <br />When installing sealant, it is optimal to <br />place the sealant where the concrete <br />touches the tightest. In the case of a <br />ship -lap or offset style joint, is it also <br />beneficial to fill the annular space. This <br />can be accomplished with one or two <br />rows of sealant, depending on the size of <br />the structure. This example shows the <br />optimal placement when using two rows. <br />As force is applied, the sealant "flows" to <br />fill the annular space. The sealant also <br />flows laterally along the inside and <br />outside mating surfaces. The sealant will <br />resist additional "flow" once it has <br />reached an equillbrium point of 10 to 15 <br />psi. Time and ambient temperature wiil <br />influence this. The result will be a gasket <br />that fills the joint as shown in this photo. <br />KNEAD SEALANT <br />INTO ONE PIECE <br />12FAIN. 12' MIN. <br />BAD BETTER BEST <br />Installation procedure around a corner <br />
