Liquiguard

Surfaces to be coated must be free of dirt, grease, flux residue and other contaminants. Use Isopropyl Alcohol for light cleaning and Lacquer Thinner for entrenched grime.
Used circuit boards may have pre-existing corrosion and cleaning may further weaken or damage corroded areas. Thus, it is essential to test each board and device, for proper operation, before applying Liquiguard.
LCD's, copper contact surfaces, connectors, battery terminals, switches, etc., must be masked before spraying. Vaseline or petroleum jelly are inexpensive and effective masking materials. Use a short bristle brush to apply it to surfaces to be protected.
Need for proper ventilation cannot be emphasized enough for health and safety reasons. Accumulated spray vapors can present a severe fire hazard. Use of face mask and safety glasses is highly recommended.
When stored in cold weather, allow Liquiguard to warm up prior to use.
Spray from a distance of 8 to 12 inches while holding the can at a 15 degree angle. Each spray cycle consists of spraying the circuit board from all four edges using steady smooth strokes. More than one spray cycle may be necessary to achieve the optimal coating thickness.
Allow a few minutes between spray cycles. Shake can vigorously between spraying. Spray both sides of the board.
Use a spray straw when coating areas that are not readily accessible. To clean spray nozzle, hold can upside down and spray for 2 to 3 seconds.
