| C. | Remove frost and moisture in concrete joint substrates before commencing sealing. |
| D. | Install bond breaker tape where needed or required by manufacturer's recommendations to ensure that elastomeric sealants will perform properly. |
| 3.2 | JOINT SEALING |
| A. | General: |
| 1. | Install sealants in uniform, continuous ribbons without gaps or air pockets, with complete bonding of joint surfaces on opposite sides. |
| 2. | Except as otherwise indicated, fill sealant rabbet flush with surface. |
| 3. | Where horizontal joints are between a horizontal surface and vertical surface, fill joint to form a slight cove so that joint will not trap moisture and dirt. |
| B. | Depths: Saw cut joints if necessary to provide the required sealant thickness and depth. Install sealant to depths indicated or, if not indicated, as recommended by sealant manufacturer, but within the following general limitations measured at center (thin) section of bead: |
| 1. | For sidewalks, pavements, and similar joints sealed with elastomeric sealants and subject to traffic and other abrasion and indentation exposures, fill joints to a depth equal to 75 percent of joint width, but not more than 5/8 inch deep nor less than 3/8 inch deep. |
| 2. | For airfield pavements, the compression joint seal shall be placed to a depth of 3/16 inch, plus or minus 1/8 inch, below the pavement surface except when the joint is beveled or has a radius at the surface. For beveled joints or joints with a radius at the surface, the compression joint seal shall be installed at a depth of 1/8 inch, plus 1/8 inch or minus 1/16 inch, below the bottom of the edge of the bevel or radius. No part of the seal shall be allowed to project above the surface of the pavement or above the edge of the bevel or radius. |
| 3. | For normal moving joints sealed with elastomeric sealants but not subject to traffic, fill joints to a depth equal to 50 percent of joint width, but not more than 1/2 inch deep nor less than 1/4 inch deep. |
| 4. | For joints sealed with non-elastomeric sealants and caulking compounds, fill joints full depth. |
| C. | Spillage: Do not allow poured sealant compound to overflow or spill onto adjoining surfaces or to migrate into voids of adjoining surfaces. Clean adjoining surfaces to eliminate evidence of spillage. |
| D. | Heating: Do not use overheated hot-applied sealants. |
| E. | Edges: Unless indicated otherwise, recess exposed edges of gasket and exposed joint fillers slightly behind adjoining surfaces so compressed units will not protrude from joints. |
| 3.3 | CURING AND CLEANING |
| A. | Cure sealants and caulking compounds per manufacturer's instructions and recommendations to obtain high early bond strength, internal cohesive strength and surface durability. |
| B. | Clean off excess sealants or sealant smears adjacent to joints as work progresses. Use methods and cleaning materials approved by manufacturers of joint sealant and of products in which joints occur. |
| C. | Remove protective coating and oil from metals with solvent recommended by the sealant manufacturer. |
| 3.4 | PROTECTION |
| A. | Protect joint sealant during and after curing period from contact with contaminating substances or from damage resulting from deterioration or damage at time of Substantial Completion. |
| B. | If damage or deterioration occurs, cut out and remove damaged or deteriorated joint sealant immediately and reseal joints with new materials to produce joint sealer installations with repaired areas indistinguishable from original work at no additional cost to Government. |
