10.1 US fl oz cartridges. (30 Tubes per box)

Color: Limestone

Applicable Standards:
Conforms to U.S. Federal Specification TT-S-00230C, Type II, Class A and ASTM C920, Type S, Grade NS, Class 25, Use NT, M, T, A, I, O, and CAN/CGSD-19.13, MCG-2-25-B-N. Conforms to USDA approval standards.


Joint Design: May be used in any vertical or horizontal joint designed in accordance with accepted architectural/engineering practice. Joint width should be 4 times anticipated movement, but not less than ¼ inch (6.4mm) wide. Movement should not exceed 25% of the minimum joint width.

Joint Dimensions:
For joints ¼ inch (6.4mm) to ½ inch (12.7mm) wide, the width to depth ratio should be equal. Joints ½ inch (12.7mm) wide or greater should have a sealant depth of ½ inch (12.7mm). Minimum joint size is ¼ inch by ¼ inch (6.4mm by 6.4mm).

Surface Preparation:
For good adhesion, the joint interface must be sound, clean and dry. Depending on the substrates, or presence of form release agents, masonry waterproofing, dust, loose mortar or laitance, architectural paints or finishes, the joint surface may require a thorough wire bushing, grinding, sandblasting, solvent washing and/or primer.

Tooling & Cleaning:
Use dish soap to tool with fingers. Tooling is recommended immediately after application to insure firm, intimate contact with the joint interface. Dry tooling is preferred. Excess sealant and smears adjacent to the joint can be carefully removed with Xylol or Toluol before sealant cures
