Shiplap Siding Installation

Prior to Installation

Always check with local building codes and an architect prior to constructing. Follow all building codes that apply in your area. Since there are many different variables one can encounter on an installation project, it is your responsibility to test the material for suitability for your project prior to constructing. Follow all manufacturers' installation instructions for the individual products used on the project. If any building codes or manufacturers installation instructions contradict or differ from information provided by AdvantageLumber.com, contact us for written clarification prior to starting your project.

Storage and Handling:

Hardwood siding should be allowed to sit where it will be installed for 7 days prior to installation in order to get acclimated to your local temperature and humidity levels. DO NOT store the siding directly on the ground, or directly on top of a concrete surface. DO NOT store the material for more than 30 days prior to use without first consulting with a sales rep at advantagelumber.com that your storage conditions are optimal. The siding should be elevated at least 12" off the ground during acclimation. To ensure the bottom boards are well ventilated, place the siding on top of blocks of wood. DO NOT cover siding material with plastic or a tarp during this acclimation period. Covering with a tarp/plastic will trap moisture in and cause stability issues. Covering the top of the pile with a sheet of plywood to shed the water is recommended. Keep material dry until installation. Also keep stickers (or wood shims) between layers of boards to allow proper air flow (see image below). DO NOT store the material in a garage or any other enclosed area.

Shiplap Siding Installation Guide

1. Apply a vapor barrier to the wall.
2. Attach 3/4" furring strips over the vapor barrier every 16".
3. Start at the bottom of the wall... To start the installation of a siding board pre-drill holes above each furring strip with a 1/8" drill bit . If Ipe Plugs are going to be used to conceal this initial fastener then a 3/8" drill bit should be used to make a hole for each Ipe Plug to fit into.
4. Drive a 3" stainless steel screw through the 1/8" pre-drilled hole in the last step. This will secure the bottom half of each siding board.
5. Next, with a 1/8" drill bit predrill a hole through the narrow part of the siding board that protrudes against the wall on the top of the board.
6. Drive a 3" stainless steel screw through the 1/8" pre-drilled hole in the last step. There is no need to worry about plugging this hole as the next board that is installed will cover this fastener.
7. Repeat the above steps for the rest of the siding boards up the wall.

Allowable Shrinkage:

When installing Shiplap Siding, install each board as tightly as possible to leave the smallest gaps between them in case shrinkage occurs. Average shrinkage is 1/8” on 4” wide boards and ¼” on 6” wide boards. Shrinkage varies depending on climate, installation site, and method of use.

Cutting & Drilling:

Due to the very hard nature of Shiplap Siding, premium carbide tipped saw blades are recommended for cutting. Brad point drill bits or fostner bits provide cleaner holes than standard HSS twist bits.

End Sealing:

Our Shiplap Siding is shipped with the end grain sealed with a clear wax to prevent any end checking and adverse movement. Fresh cuts should be sealed within 24hrs with end grain sealant. We sell end grain sealant by the quart, which is typically enough for 500 sq.ft. of siding. The end grain sealant is simply applied with a paintbrush and dries clear. DO NOT apply end seal to the surface of the siding. Any sealant that gets on the surface should be wiped off immediately.

Finishing:

Because of Exotic Hardwood's natural density and alkaline characteristics, many oil and water based finishes will not dry properly when applied. We recommend that you test any product on several sample boards to determine compatibility. The finish we sell and recommend is Ipe Oil™. We do not recommend the use of other finishes. Applying a finish approximately every two years (depending upon your local climate) can help keep the beautiful dark brown color. If you decide to let your deck weather, it will turn a silvery gray similar to teak. We recommend that you apply a coat of finish initially after deck installation, regardless of the final color desired. This can help ensure that the Ipe retains its oils and stability. For low ventilation applications, we recommend finishing deck boards on all four sides prior to installation but after acclimation.
