Treat drywall joints and nailheads with a U.S. Gypsum Company joint treatment system.
Mixing Stir gently. Do not thin for brush or roller application. For spray application, if necessary, add water in half-pint
increments up to a maximum 1 qt. of water per gallon.
Note: Overthinning may cause poor adhesion, lack of hide and unequal suction when dry. May be tinted.

Application Apply a full coverage coat. Material dries to touch in under 30 min. in 75 °F/50% R.H. conditions. Maintain
minimum air, product mix and surface temperature of 55 °F (13 °C) during application and until surface is dry.
Brush Use a high quality, professional paint brush.
Roller For best results, use a high quality roller with 1/8 to 1/4 nap on smooth and semi-smooth surfaces. For any
