In cold weather and during gypsum panel joint finishing, temperatures within the building shall be maintained at a minimum of 55°F (13°C). Adequate ventilation shall be provided to carry off excess moisture.
Before applying store at 55-95°F (13-35°C) for 24 hours. Remix contents before use. When taping and finishing joint, thinning with water may improve application. Add clean water in half-pint increments, remix and trial apply until preferred consistency is reached. Over-dilution causes abnormal shrinkage, poor bond and other negative effects. Do not mix with any other material.
Cover joint with a thin layer of compound and embed paper tape, leaving about 1/32 in. of compound under feathered edge. Let dry and sand lightly. Apply second coat, feathering approximately 2 in. beyond first coat. Let dry, then dry trowel/scrape or sand lightly to remove tool marks as required, and then apply third coat, feathering 2 in. beyond second coat. Sand lightly as required when dry. Finish fastener heads, corner bead and inside corners as required with at least three coats of joint compound, feathered out onto panel faces and finished to a smooth surface.
