SL1 - Self Leveling Pool Caulk

SL1 Sonolastic Self Leveling Polyurethane Sealant is a one-component self-leveling non-priming polyurethane sealant designed for expansion joints in concrete floors and decks. Use Sonneborn SL1 Sonolastic Self Leveling Polyurethane Sealant where flexibility as well as abrasion and puncture resistance are required.

Features Benefits:

• Movement capability of ñ25% expands and contracts with joint movement
• Abrasion resistant provides longer wearing and durability
• Easy to gun installs quickly
• Variety of types and sizes of packaging reduces job site waste
• Nonpriming on most surfaces offers excellent adhesion
• Self levels requires no tooling
• Wide application-temperature range suitable for all climates
• Excellent weatherability offers long-lasting performance

How to Apply:

1. The number of joints and the joint width should be designed not to exceed ñ25% movement.
2. The depth of the sealant should be 1/2 the width of the joint. The maximum depth is 3/8" (10 mm) and the minimum is 1/4" (6 mm). Maximum recommended joint width is 1-1/2" (38 mm).
3. In deep joints, sealant depth must be controlled with Backer-Rod (closed cell only) or Expansion-Joint Filler (see Form Nos. 1017927 and 1017916). Other caulks should not be used as fillers. Do not prime Backer-Rod or Expansion Joint Filler. Do not puncture backer-rod; it may cause bubbling.
4. Caulking and sealing should be performed when temperatures are above 40ð F (4ð C). Application to moist surfaces will adversely affect adhesion. Application may proceed as low as 20ð F (-7ð C) only if substrates are clean and completely free of moisture or frost.
