Duration Moulding & Millwork 1-3/8 in. x 1-3/8 in. Sub-Sill Moulding, Poly-Ash, 8 ft.

Surface Preparation:

1. Clean and Dry Surface: Ensure that the wall and ceiling areas where the molding will be installed are clean and free from dust, grease, or debris. Use a cloth or vacuum to remove any dust from the surface.
2. Measure and Cut: Accurately measure the lengths of molding you will need. Use a miter saw or coping saw to cut the molding at the appropriate angles, typically at 45 degrees for corners. Ensure all cuts are smooth to fit snugly.
3. Dry Fit the Molding: Before applying any adhesive or fasteners, dry fit the pieces to ensure that they align properly and fit the space well.

Installation Instructions:

1. Mark the Placement: Use a pencil to lightly mark the line on the wall or ceiling where the top edge of the molding will be placed. A laser level can be helpful to ensure the molding will be straight across the entire room.
2. Apply Construction Adhesive (Optional): Apply a strong, construction-grade adhesive to the back of the crown molding. This will help hold the molding in place while you fasten it. Ensure an even layer of adhesive.
3. Position and Secure the Molding: Carefully position the molding along the marked line on the wall or ceiling. Press it into place. You can hold it temporarily with painter's tape while securing it with nails.
4. Fasten with Nails or Screws: Use finish nails, a pneumatic nail gun, or screws to secure the crown molding to the wall or ceiling. The nails should be driven at an angle, and any visible nails should be filled with wood filler for a seamless finish.
5. Mitering the Corners: For inside and outside corners, measure and miter the molding pieces at 45-degree angles. For a cleaner joint, consider using pre-mitered corner pieces or corner blocks.
6. Seal Gaps: Apply caulk or paintable silicone to fill any visible gaps between the wall, ceiling, and molding for a smooth, professional finish.
7. Touch-Up: If the molding is unfinished or if nail holes are visible, you can touch up the molding with matching paint, stain, or a wood finish. If it's pre-finished, simply ensure that all joints and seams are properly sealed.

Drying and Curing Times (if applicable):

• Adhesive Dry Time: Allow construction adhesive to dry as per the manufacturer's instructions, typically 24 hours for full bonding.
• Paint or Finish Dry Time: If the molding is unfinished, allow paint or wood finish to dry completely between coats (typically 2–4 hours depending on humidity and temperature).
• Curing Time: Full curing of paint or adhesive can take up to 48 hours for optimal results.

Maintenance and Care:

• Regular Cleaning: To maintain the molding, simply dust it regularly with a soft cloth or a duster. For more stubborn marks, you can use a damp cloth with a mild soap solution.
• Touch-Ups: If you notice any scuffs or scratches over time, you can use a touch-up marker, paint, or stain to restore the finish.
• Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on Poly Ash moldings, as they may damage the finish.
