Is this an exterior product?

Absolutely.  This product is specifically designed for exterior use.  It is treated with Tru-Core® treatment technology that treats the board throughout and protects against rot, decay, and insects, and is backed by a 50 year warranty.  It is a excellent choice for those doing fine exterior trim work and paneling, and those looking for a best-in-class pre-primed trim and pattern.  


Where should I use this product?

It's best to use this for exterior siding or living areas where it is exposed to the weather.  It can also be used in an interior application that is susceptible to high levels of moisture, such as a bathroom, or even a covered porch or deck.  


What's the actual nickel gap width?  Can it be a wider or thinner thickness?

The actual gap measures 1/8" wide.  You can use spacers when installing to make it wider if preferred.  


I noticed that this is a primed only product.  Does it come pre-painted?  Do I have to paint it?

This is a primed only product and it must be painted for the warranty.  However, there is no color spectrum limit and our Premium Primed Exterior Shiplap can be painted any color, even dark grays and blacks.  


What colors and type of paint should I use?

You can paint our Premium Primed Exterior Shiplap any color of paint, including black and dark grays.  As for the type of paint, a high-grade exterior paint is recommended.  Because this product is highly resistant to moisture cycling, the paint will adhere and perform well over the longevity of the siding.  


What's the lifespan of the product?  Is there a warranty? 

Premium Primed Exterior Shiplap is a great performing product and will last for decades when properly installed.  It's covered by an incredible 50-year warranty. 


What is it made out of?

This is a finger jointed Radiata Pine that is fully primed and fully treated for both interior and exterior use.  It's made using Tru-Core® treatment technology that treats the board throughout and protects against rot, decay, and insects, and is backed by a 50 year warranty.


What is the lead time on this product once I place my order with the dealer?

Typical lead time is one week for delivery to your door.  If you happen to have a particularly large job, or are located outside of our normal dealer network, you may need to allow for a longer lead time.  However, we will always communicate with you if a situation like this arises.


How do I install Premium Primed Exterior Nickel Gap?

Our Premium Primed Exterior Shiplap is simple to install and very carpenter friendly.  It uses standard woodworking tools and installs like regular wood.  Below are the basic installation requirements.  

  • Ensure a minimum 8” ground clearance after final installation
  • Use annular-ringed, hot-dipped, galvanized steel, stainless steel or aluminum shanked nails
  • Countersink nails 1⁄16” below the siding surface to allow for filling prior to painting
  • Ensure nails penetrate solid wood sheathing, studs or blocking by 1 1/2”
  • Fill all nail holes with exterior grade wood filler, then spot prime
  • Apply two full coats of 100% acrylic premium quality exterior house paint as per paint manufacturer’s label instructions

What fasteners do they recommend using?

Use annular-ringed, hot-dipped, galvanized steel, stainless steel or aluminum shanked nails.  Two fasteners should be used at each framing member (simply fastening through the tongue alone is not sufficient).  


Do I need to face nail, or can I blind nail to hide the fasteners?

Two fasteners are required at every framing member.  At least one fastener should be through the face of the profile, simply fastening the product through the tongue alone is not sufficient.  We recommend using two fasteners through the face every 16" O.C. for best results.  


How do I hide the nail or screw heads when fastening through the face?

Filling nail and screw holes or repairing any minor damage caused by handling may be done using high-grade acrylic caulk or wood fillers.  Then, using a high quality exterior grade paint will sufficiently cover and hide fastener marks.
