• Site Conditions: A temperature of 55°F(13°C) shall be maintained at least 48 hours prior to application and up until joint compound is thoroughly dry.
• Continuous ventilation must be provided to take away excess moisture during the drying period.
• Application: Mix contents thoroughly in the box without adding water or, if using mechanical taping tools, thin as necessary. Water should be added in 125ml(1/2 cup) increments to avoid over thinning. For best results remix before application. Apply Platinum Lite to all joints then embed tape, remove excess compound leaving a uniform thickness of .8mm(1/32 in.) under the tape. Allow joint com-pound to dry before applying second or subsequent coats, width of second joint treatment should be about 8” (203mm) wide. Cover joints a third time toa width of 10-12” (254mm-305mm) ,feathering material to a diminishing edge. Cover cornerbeads and fasteners with joint compound until completely covered keeping in mind to allow the applied material to completely dry before next application.
• Sanding: Sand with a wet sponge or using a 150 grit paper or finer. Once the last coat has dried, excess material and imperfections can be removed leaving a feathered finish ready to be primed. It is important the during the sanding process that the papered surface of the gypsum board is not roughed up from sanding. This will scuffing will show up after the finish paint has been applied. When sanding eye protection and a NIOSH approved dust mask should be worn.
• Decoration: The dried, finished product should dust free, and sealed with a quality primer or with a high solid latex paint. All surfaces can then be finished with paint or wall paper. Paint manufacturers instructions should be adhered to during the process.

Handling and Use

1. Surface Preparation

• Ensure drywall seams are properly taped with joint tape to reinforce the compound.
• Remove dust and debris from the surface to promote proper adhesion.
• If patching holes or imperfections, clean the area and apply a suitable backing if needed.

2. Application Process

• First Coat: Use a putty knife or drywall trowel to apply a thin, even layer of compound over joints and screw holes. Feather the edges to blend with the surrounding wall.
• Second & Third Coats: Allow the first layer to dry completely before applying additional coats. Each coat should be slightly wider to create a seamless transition.
• Texturing (if needed): For decorative finishes, use specific tools or techniques to create desired textures before the compound dries.

3. Sanding & Finishing

• Once fully dried, sand the surface with fine-grit sandpaper to eliminate rough areas and create a smooth finish.
• Remove dust before priming and painting to ensure optimal adhesion.

4. Final Touches

• Apply primer to seal the drywall compound and prepare it for paint or wallpaper.
