Description

MasterSeal SL2 Slope Grade is a multi-component, self-leveling, elastomeric polyurethane sealant. It is mixed and poured in place. When cured, it forms a tough, resilient joint seal that resists penetration, abrasion, and remains flexible when exposed to weather and aging.Wide temperature-application range makes MasterSeal SL 2 Slope Grade suitable for all climates. UL listed; Passes 4-hour, 4-inch, fire and hose stream test when used with Ultra Block or mineral wool. Suitable for water immersion with documented performance in wet areas. Bulk packaging results in less waste. Formulated to withstand pedestrian and vehicular traffic. Questions about SL2 Slope Grade? Contact Us.

Joint Preparation:
1.The product may be used in sealant joints designed in accordance with SWR Institute’s Sealants – The Professional’s Guide.
2. In optimal conditions, the depth of the sealant should be ½ the width of the joint. The sealant joint depth (measured at the center) should always fall between the maximum depth of ½” and the minimum depth of ¼”. Refer to Table 1.
3. In deep joints, the sealant depth must be controlled by closed cell backer rod or soft backer rod. Where the joint depth does not permit the use of backer rod, a bond breaker (polyethylene strip) must be used to prevent three-point bonding.
4. To maintain the recommended sealant depth, install backer rod by compressing and rolling it into the joint channel without stretching it lengthwise. Closed cell backer rod should be about 1⁄8″ (3 mm) larger in diameter than the width of the joint to allow for compression. Soft backer rod should be approximately 25% larger in diameter than the joint width. The sealant does not adhere to it, and no separate bond breaker is required. Do not prime or puncture the backer rod.

Application:
1. All caulking and sealing should be performed when temperatures are above 40° F (4° C); any moisture or frost on surfaces will adversely affect adhesion.
2.Fill joints from the bottom; avoid bridging of the joint, which may form air voids.
3.For large joints, the self-leveling grade may be poured directly from the can.
4.For smaller joints and for all slope-grade applications, fill the joint by flowing the sealant from a bulk-loading gun.
5. Light tooling of the slope-grade sealant is recommended to smooth out ripples. On sloped surfaces, tool from the lowest point to the highest. Do not use soap or solvent.
