Installing PVC molding in a bathroom involves careful measurement, cutting, and attachment, along with finishing touches to create a clean, waterproof seal. Here's a step-by-step guide:
1. Preparation is Key
- Gather your materials and tools: You'll need PVC molding, a measuring tape, a miter saw (or hand saw with a miter box), construction adhesive specifically for PVC, a brad nailer (optional, but recommended), a caulk gun and paintable caulk, wood filler (if using nails), sandpaper, paint (if desired), safety glasses, and a pencil.
- Remove existing baseboard: Use a pry bar and a utility knife to carefully remove any existing baseboard, being mindful not to damage the wall. Patch any holes in the wall with spackle and let it dry. Sand smooth.
- Clean the area: Ensure the area where you'll be installing the molding is clean, dry, and free of debris.
2. Measuring and Cutting the PVC Molding
- Measure the walls: Accurately measure the length of each wall where you'll be installing the PVC molding. Account for outside corners, which typically require 45-degree miter cuts.
- Cutting the molding: Use a miter saw to cut the PVC molding according to your measurements. Ensure precise cuts, especially for corners, to create a seamless finish. Remember the saying: "Measure twice, cut once!"
- Inside corners: For inside corners, you have two options:
- Coping: This involves cutting one piece of molding square and then using a coping saw or knife to cut the second piece to match the profile of the first. This method often provides the best fit.
- Miter: Alternatively, you can miter inside corners at 45-degree angles, but this may require more precise cuts and caulking to fill any gaps.
- Test fit: Before permanently attaching the molding, dry-fit each piece to ensure a proper fit. Make any necessary adjustments.
3. Attaching the PVC Molding
- Apply construction adhesive: Apply a bead of PVC-specific construction adhesive to the back of the molding where it will contact the wall.
- Secure with brad nails (optional): If using a brad nailer, drive nails through the molding and into the wall studs or drywall anchors. This will help hold the molding in place while the adhesive cures. If not using a nailer, use painter's tape to secure the molding until the adhesive is dry.
- Proper placement: Ensure the molding is level and flush against the wall.
4. Finishing Touches
- Fill nail holes (if applicable): If you used a brad nailer, fill the nail holes with wood filler and let it dry. Sand smooth.
- Caulk the gaps: Apply a bead of paintable caulk along the top edge of the molding where it meets the wall and along the bottom edge where it meets the floor. This will create a watertight seal and hide any imperfections. Smooth the caulk with a wet finger or a caulk smoothing tool.
- Painting (optional): If desired, paint the PVC molding with a high-quality paint suitable for PVC. Apply primer first for better adhesion.
5. Tips for Success
- Use PVC-specific adhesive: Regular construction adhesive may not bond well to PVC.
- Clean up excess adhesive and caulk: Use a damp cloth to wipe away any excess adhesive or caulk before it dries.
- Consider quarter round: If you have significant gaps between the baseboard and the floor, consider installing quarter round molding along the bottom edge to cover them.
- Safety first: Always wear safety glasses when cutting and installing molding.
By following these steps, you can successfully install PVC molding in your bathroom, creating a finished and waterproof look.
