Install joint - sealant backings of kind indicated to support joint sealants during application and at <br />position required to produce cross - sectional shapes and depths of installed sealants relative to <br />joint widths that allow optimum sealant movement capability. <br />1. Do not leave gaps between ends of joint - sealant backings. <br />2. Do not stretch, twist, puncture, or tear joint- sealant backings. <br />3. Remove absorbent joint - sealant backings that have become wet before sealant application <br />and replace them with dry materials. <br />D.

Place joint sealants so they directly contact and fully wet joint substrates. <br />2. Completely fill recesses in each joint configuration. <br />3. Produce uniform, cross - sectional shapes and depths relative to joint widths that allow <br />optimum sealant movement capability. <br />E. Tooling of Nonsag Joint Sealants: Immediately after joint - sealant application and before <br />skinning or curing begins, tool sealants according to the following requirements to form <br />smooth, uniform beads of configuration indicated; to eliminate air pockets; and to ensure <br />contact and adhesion of sealant with sides of joint: <br />1. Remove excess joint sealant from surfaces adjacent to joints. <br />2. Use tooling agents that are approved in writing by joint - sealant manufacturer and that do <br />not discolor sealants or adjacent surfaces. <br />F. Provide joint configuration to comply with joint - sealant manufacturer's written instructions <br />unless otherwise indicated. <br />3.4 CLEANING <br />A. Clean off excess joint sealant or sealant smears adjacent to joints as the Work progresses, by <br />methods and with cleaning materials approved in writing by manufacturers of joint sealants and <br />of products in which joints occur. <br />3.5 PROTECTION <br />A. Protect joint sealants, during and after curing period, from contact with contaminating <br />substances and from damage resulting from construction operations or other causes so sealants <br />are without deterioration or damage at time of Substantial Completion.
