General Purpose Setting Type Basecoat application
Place 5 liters of water in a container. Start the mixer; slowly add USG General Purpose Basecoat and mix until to obtain a homogeneous mixture. Add more water if is necessary. Approximate water-cement ratios for Basecoat (hand or machine application) are 6 liters per bag. Mix plaster with a cage-type paddle driven by a heavy-duty drill capable of producing 300 to 450 rpm.
When the mixture is smooth and free of lumps, let stand 15 minutes, and then re-mix to a smooth paste. The surface where you will apply the cement must be completely clean, dry and free of dust, ice, grease, oil or other substances that may prevent adhesion.
Fill joints with General Purpose Basecoat with a HammerEnd Joint Knife and then place the reinforcing exterior tape, retroweling removing excess of Basecoat in order to embed the tape. Cover corners and vinyl beads. The thickness of the General Purpose Basecoat must be thin, no more than 1 mm. Remove excess with a flat metal wool or polystyrene wet. Allow dry at least 4 hours.
Once the joints are dry, apply a uniform layer of 2 mm thick over the entire surface of Basecoat with a flat trowel. Allow dry at least 24 hours before applying any seal or finish
