Installation:
Apply by spraying, brushing or rolling the paint-like A77 coating to all areas of cables and cable runs. When spraying use equipment like the Graco (U.S.) airless sprayer, Type ELTG 433GT with the special pump President (15:1) and a nozzle size of 0.74 mm (0.029 in.). (The pressure has to be adjusted until a workable condition is obtained).
Two coats of A77 are required. To achieve proper coverage for both coats, we recommend the following:
Since A77 comes in two colors, white and gray, order both colors, use one color for the first coat and use the second color for the second coat. Depending on the depths of the coats, the quantities needed of the two colors may differ.
First coat of A77 will end up being about 0.5 mm on vertical surface and 1 mm on horizontal surface. Let dry for 24 hours.
Spray or brush a second coat so that the total thickness of the A77 coat, including the first coat is 2.5 mm (wet), which will dry to about 1.59 mm thick layer, as requirement of Factory Mutual.
Initial curing takes 4 to 8 hours, with final curing in 24 to 48 hours.
After the second coat is dry in 48 hours, check if any spots are not covered. (A77 is white so look for dark spots and add A77 to those places).
Clean-Up:
Clean up tools and spills by using wet cloth or soap and water.
