How to Install Vertical Shiplap Over Drywall

Are you looking to add a touch of rustic charm to your home's interior? Vertical shiplap over drywall is a popular choice for creating a farmhouse or industrial-style accent wall. This guide will walk you through the process of installing vertical shiplap over drywall, from gathering materials to the final finishing touches.

Before you start, ensure you have the right tools and materials. You'll need a miter saw, jigsaw, tape measure, level, circular saw, hammer, finish nails, and a nail set. For materials, you'll need shiplap boards, drywall screws, joint compound, sandpaper, and primer.

Preparation and Measurement

Start by measuring the wall where you'll be installing the shiplap. Mark the studs using a stud finder, as you'll need to attach the shiplap to these for support. Also, measure and mark the height of your first row of shiplap, ensuring it's level.

Cut your shiplap boards to size. Remember, shiplap is installed vertically, so you'll be cutting the boards to the height of your wall, not the width. It's a good idea to cut a few extra boards to account for mistakes or waste.

Starting the First Row

Begin at the bottom left corner of your wall. Apply a bead of construction adhesive along the bottom of the first board, then attach it to the wall using drywall screws, driving them into the studs. Ensure the board is level and plumb.

Use a nail set to countersink the screws, then fill the holes with joint compound. Sand the compound smooth once it's dry. This will help ensure a seamless finish when you paint.

Installing the Remaining Boards

Install the remaining boards in the first row, using spacers to ensure consistent gaps between them. Shiplap typically has a 1/8" gap between boards, but you can adjust this to suit your preference. Use a level to ensure each board is straight and plumb.

Once the first row is complete, move on to the second row. Stagger the joints between boards for added strength and stability. Continue this process until you've covered the entire wall.

Finishing Touches

Once your shiplap is installed, it's time to prepare it for painting. Use a putty knife to apply joint compound to the seams between boards. Allow it to dry, then sand it smooth.

Apply a coat of primer to the shiplap. This will help seal the wood and create a smooth surface for painting. Once the primer is dry, you can paint your shiplap any color you like.

Congratulations! You've successfully installed vertical shiplap over drywall. This charming accent wall is sure to be a conversation starter. Don't forget to step back and admire your handiwork. If you're feeling inspired, consider adding shiplap to other rooms in your home for a cohesive look.
