Merlex Fog Coat is designed to be applied to portland cement surfaces which have not been painted or sealed. All receiving surfaces must be structurally sound, clean, free of dust, dirt, silicones, paint products, efflorescence or any other containment which could impair the natural bond. For hand applications the substrate should be dampened with clean potable water to control suction. Major cracks, holes, or voids should be repaired prior to application. Note: For application over smooth surfaces contact a Merlex representative for special recommendations.

Add enough clean water to form a heavy paste (about 1 qt. (.95 ltr.) water per each 5 lbs. (2.3 kg.) of Fogcoat) and mix in paste consistency until no lumps remain. Allow to stand for approximately 10 minutes. Add additional water to bring to the approximate consistency of milk and stir thoroughly. (Approximately 1/2 gal. (1.9 ltr. of water per 1 lb. (.454 kg.) of Fogcoat or 13-16 gals. (12.3 - 15.2 ltr.) per 25 lb. (11.35 kg.) bag.) Strain through a fine mesh screen i.e., painters' screen, nylon stocking, etc. Caution: DO NOT OVER DILUTE.

Merlex Fog Coat may be applied using a portable hand pump sprayer, an airless sprayer or a pressure tank-type sprayer. Note: Hoses should be sufficiently long enough to allow efficient application. For maximum results use a nozzle which forms a fan spray pattern. Stir or shake container frequently during application to prevent settling. PRIOR TO APPLICATION, IT IS ADVISABLE TO TEST A SMALL AREA TO CHECK COLOR.

Holding the nozzle approximately 2 ft. (.6 m) away from the wall, apply Fog Coat in a crosscoat fashion to insure even coverage. Normal procedure is to apply from one architectural stoppage to another, such as a corner to corner or control joint to control joint. Normally it is not advisable to spot fog a wall. However, in certain cases it can be done successfully.

Apply two thin coats, allowing ample time (approximately 15 min.) between coats for the first to dry. Do not apply the second coat until the first coat has dried. Always avoid heavy buildups. For two story buildings, extension wands may be employed to accomplish spraying from the ground.

Overspray that gets onto glass, painted wood and metal surfaces should be allowed to dry before wiping off. However, it is always best to protect all other surfaces with proper masking prior to application. For production work, apply Fog Coat to the plaster before window cleaners begin their operation.
