Armorflex 962/963 Flexible Joint Compound is a 100% solids, polysulfide epoxy compound. It has excellent elongation properties and will bond to almost any surface. AF 962/963 is especially useful for expansion joints, tiltwall joints, along caulk lines, and in other locations where both waterproofing and control of movement are required.

Various aggregates and fillers can be added to Armorflex 962/963 to improve appearance, increase abrasion resistance, or meet engineering and architectural specifications. Some custom colors are available by request.

Miscellaneous

• Flexes more than 50%, while maintaining 100% bond – holds its bond in expansion and contraction.
• Cures in the presence of moisture – can be applied in dry or damp conditions.
• Easy to mix and apply – adaptable to many applications and service conditions.
• Produces impervious barrier – prevents contamination from water, solvents, and a variety of chemicals.

A prime coat of Armor Plate 901 Tack or Prime may be applied to the surfaces to be filled if excessive movement, uncertain surface preparation, or doubtful bonding ability is anticipated.

Armorflex 962 and 963 are two-component systems which are mixed just prior to application. The mixing ratio is 1 part Resin (part A) to 2 parts Cure (part B). The two parts are mixed in a clean container until the mixture is thoroughly blended and of a proper consistency. AF 962 will have a paste consistency and AF 963 will be a pourable liquid.

Armorflex 962 is applied to properly prepared surfaces by trowel or caulking gun. Armorflex 963 is poured into properly prepared joints.
Tools and equipment used may be cleaned with Armor Plate Equipment Cleaner. DO NOT use Armor Plate Equipment Cleaner for personal cleanup.
The proper depth of the sealant is approximately one-half the width of the joint. The sealant depth should not be greater than the width of the joint. The joint width should be designed so that the maximum elongation of the joint sealant will not exceed 50% of the original width. The distance between expansion joints and the expected variance in service temperatures should be considered in designing the proper joint width. The Joint Width Design table below will aid in designing joint widths.
