Installing PVC Shiplap: A Comprehensive Guide
PVC shiplap has become a popular choice for homeowners looking to add a touch of rustic charm to their walls. Its durability, low maintenance, and versatility make it an excellent alternative to traditional wood shiplap. This guide will walk you through the process of installing PVC shiplap, ensuring a professional finish that will last for years to come.
Understanding PVC Shiplap
Before you begin, it's essential to understand what PVC shiplap is and its benefits. PVC (polyvinyl chloride) is a synthetic plastic polymer commonly used in construction due to its resistance to moisture, rot, and pests. Shiplap refers to a type of board with a rabbet (groove) on one edge and a tongue on the other, allowing boards to overlap and create a tight seal.
Tools and Materials Needed
- PVC shiplap boards
- Circular saw
- Jigsaw (for cutting around obstacles)
- Tape measure
- Level
- Chalk line
- Construction adhesive
- Finishing nails (16-gauge, 2-inch)
- Hammer or nail gun
- Safety gear (gloves, goggles, ear protection)
Preparation: Measuring and Planning
Before you start cutting and nailing, take the time to measure and plan your layout. PVC shiplap comes in standard widths (usually 6 or 8 inches), but the length can vary. To minimize waste, start with the longest boards and work your way down. Also, consider the direction you want the shiplap to run – horizontally or vertically.

Installing the First Row
The first row is crucial as it sets the tone for the rest of the installation. Start by snapping a chalk line along the wall where you want your bottom edge to be. This will serve as your guide for the first row. Apply a bead of construction adhesive along the chalk line, then attach the first board using finishing nails. Ensure the board is level and flush with the wall.
Installing Subsequent Rows
For each subsequent row, start with the leftmost board. Apply construction adhesive to the tongue of the board below, then fit it into the groove of the board above. This will create a tight, overlapping seal. Use a level to ensure the board is straight, then nail it in place. Continue this process, working your way across the wall.
Dealing with Obstacles
Walls are rarely perfect rectangles, and you'll likely encounter obstacles like outlets, light switches, or windows. When you reach an obstacle, measure and mark the board where it needs to be cut. Use a jigsaw to make the cut, ensuring it's clean and smooth. Once the board is cut, fit it into place and nail it down.

Finishing Touches
Once you've installed all the boards, it's time for the finishing touches. Fill any nail holes with spackling compound, then sand them smooth. You can then paint or stain the shiplap to match your desired aesthetic. Remember to prime the shiplap first to ensure better paint adhesion and protection.
Maintenance and Care
PVC shiplap is incredibly low maintenance. To clean it, simply wipe it down with a damp cloth and mild soap. Avoid using harsh chemicals or abrasive materials, as they can damage the PVC. With proper installation and care, your PVC shiplap will maintain its beauty and functionality for years to come.
