To achieve the best results, Armor Plate 999 should be kept at about 70 °F prior to application.
Armor Plate 999 is poured to a depth of between 1.5 and 4 inches. The maximum depth of a pour in large areas should not exceed 4 in., unless reinforcing is used. Pours deeper than 4 in. may be made in small areas only. Use rebar steel or clean rocks as a heat sink in deep areas.
Consecutive pours (maximum 4 in.) may be made without reinforcing after each previous layer has cured and its heat has dissipated. Previous pours should be sanded or chipped before the next pour is made.
Provide expansion joints every for (4) to five (5) feet.
Armor Plate 999 may be pumped when grouting wide, shallow areas. For pumping information Contact Wil-Cor, Inc. for equipment rental rates and supervision.
Armor Clean, MEK, Methylene Chloride or gun cleaner may be used to clean equipment.
The table below gives an estimate of the working and cure times of AP 999 at various temperatures. The times are approximations and will vary with humidity and desired service conditions.
