Masking Tape: Use masking tape where required to prevent contact of sealant with adjoining surfaces that otherwise would be permanently stained or damaged by such contact or by cleaning methods required to remove sealant smears. Remove tape immediately after tooling without disturbing joint seal. 3.3 INSTALLATION OF JOINT SEALANTS A. General: Comply with joint-sealant manufacturer's written installation instructions for products and applications indicated, unless more stringent requirements apply. JOINT SEALANTS 1346 079200-5

Install sealants using proven techniques that comply with the following and at the same time backings are installed: 1. Place sealants so they directly contact and fully wet joint substrates. 2. Completely fill recesses in each joint configuration. 3. Produce uniform, cross-sectional shapes and depths relative to joint widths that allow optimum sealant movement capability. F. Tooling of Nonsag Sealants: Immediately after sealant application and before skinning or curing begins, tool sealants according to requirements specified below to form smooth, uniform beads of configuration indicated; to eliminate air pockets; and to ensure contact and adhesion of sealant with sides of joint. 1.

Protect joint sealants during and after curing period from contact with contaminating substances and from damage resulting from construction operations or other causes so sealants are without deterioration or damage at time of Substantial Completion. If, despite such protection, damage or deterioration occurs, cut out and remove damaged or deteriorated joint sealants immediately so installations with repaired areas are indistinguishable from original work.
