Joint Design

May be used in any joint designed in accordance with accepted architectural/engineering practices. Joint width should be 4 times anticipated movement, but not less than 1/4 inch (6mm) wide. Movement should not exceed 25% of the minimum joint width.

Joint Dimensions

For joints 1/4 inch (6mm) to 1/2 inch (13mm) wide, the width to depth ratio should be equal. Joints 1/2 inch (13mm) wide or greater should have a depth of 1/2 inch (13mm). Minimum joint size 1/4 inch by 1/4 inch (6mm by 6mm).

Surface Preparation

For good adhesion, the joint interface must be sound, clean and dry. Depending on the substrates, the joint surface may require a thorough wire brushing, grinding, sandblasting, solvent washing and/or primer.

Tooling & Cleaning

Tooling is recommended immediately after application to ensure firm, intimate contact with the joint interface. Dry tooling is preferred. Cleaning can be accomplished with solvents such as IPA or MEK while sealant is in an uncured state.
