POLAJOINT is a 100% solids, two component, pourable, modified epoxy which forms a semi-hard durable joint compound. It is ideal for filling joints or cracks in concrete or steel infrastructure that have little or modest movement. POLAJOINT remains firm and hardwearing while accommodating a mild degree of movement in the structure. It is highly resistant to acids, alkalis, solvents and oils, and will maintain adhesion to the surfaces of the joint or crack.
OUTSTANDING FEATURES:
§
Will repair damaged, broken concrete to restore slab integrity
§ Maintains performance under high temperature conditions
and thermal cycling
§
Self-levels into interstices during application to eliminate voids
§ Highly resistant to mechanical damage
§
Seals effectively between concrete and steel
§ Provides protection for wide cracks and joints; has fast cure time
§
Forms an effective chloride-ion barrier
§ Exhibits good chemical resistance; prevents chemical seepage into most joints
§
Does not produce any offending odor during application
§ Has no shrinkage;
maintains excellent dimensional stability

APPLICATION:
Caution! READ THIS ENTIRE DATA SHEET BEFORE CONTINUING.
All surfaces to be coated must be dry and free of loose debris, oils, paints, grease and other substances that would interfere with proper bond. For proper repair of irregular cracks, it may be necessary to router out the crack into a symmetrical "U" shape. It is advisable to prime highly porous surfaces or very dense concrete surfaces with Polaprime 21. Very deep joints or cracks need to be filled with a proper diameter backer-rod material such as Dow Ethafoam.
In a clean dry container, mix the complete 2 part unit for at least 5 minutes with low speed mixing. Try not to entrap excessive quantities of air when mixing. After thorough mixing, Polajoint may be poured into the crack or joint through a pouring spout or with a refillable caulking gun. Completely fill the crack or joint. It may be necessary to top off the filled crack or joint after a few minutes of settling and
air release takes place. Equipment can be cleaned with xyline or toluene BEFORE the product cures.
LIMITATIONS:
In exterior situations, Polajoint will darken in color with time. This will not, however, adversely affect performance. Shelf life is 12 months when stored in tightly sealed containers.
MAINTENANCE:
If a section of repaired joint or a repaired crack becomes damaged, prepare the area thoroughly in accordance with instructions under the Application section of this data sheet. Pour Polajoint into the prepared area until it flows to a level contact with the adjoining Polajoint areas.
PRECAUTIONS:
Gloves, goggles, and barrier cream must be worn during application. Remove skin contamination as soon as possible with a resin remover. In case of eye contact, flush with clear water for 15 minutes and seek immediate medical attention. If ingested, induce vomiting and seek immediate medical attention. Do not eat or smoke while handling this material or in the immediate vicinity before it is fully cured.
