Frequently Asked Questions: 

Q: What is TruExterior made out of?

A: TruExterior trim and siding is the first and only Poly-ash trim product, consisting of a blend of proprietary polymers and coal combustion products (ash).

Q: How do I install TruExterior?

A: TruExterior is incredibly simple to install, and very carpenter friendly.  It uses standard woodworking tools and handles very similarly to regular wood.  Installation is three simple steps - just cut, fasten, and paint.  There are no special installation techniques or restrictions in regards to gapping, butt joints, or priming edges or field cuts.  

Q: What fasteners do they recommend using?

A: It is recommended to use an 8d x 2 1/2" Stainless Steel Ring Shank Nail.  Fasteners should be installed at 16" - 24" O.C. or less.  Two fasteners should be used at each framing member (simply fastening through the tongue alone is not sufficient).  

Q: What colors and type of paint should I use?

A: You can paint TruExterior any color of paint, including black and dark grays.  As for the type of paint, a high-grade exterior paint is recommended.  Because TruExterior is highly resistant to moisture cycling, the paint will adhere and perform well over the longevity of the siding.  

Q: Can I take TruExterior straight to grade or concrete?

A: Yes!  One of the best features of TruExterior is its ability to go straight to grade or but tight to concrete or masonry.
