Radiata White Pine ACX Plywood – Exterior Grade with Premium Paintable Face

ACX plywood is widely used for various outdoor and indoor applications that demand strength and weather resistance. It is commonly employed in exterior construction such as sheathing, roofing, siding, and subflooring for outdoor structures. Its smooth surface and durable, waterproof adhesive also make it suitable for furniture construction and cabinetry, especially when a high-quality finish is desired. Additionally, ACX plywood is utilized in commercial and industrial projects like packaging and pallets due to its strength and waterproof properties. It is also favored in boat building because of its waterproof qualities and durability, as well as in workshop projects such as workbenches, shelving, and outdoor furniture. Its waterproof adhesive and robust construction make it versatile for any application exposed to moisture or harsh weather conditions.

Additional Information

  • A-Grade Face & C-Grade Back: The front face is A-grade, ensuring a clean, knot-free surface that’s perfect for painting or finishing. The back face is C-grade, allowing for knots and blemishes where appearance is less important, making it ideal for structural and utility purposes.
  • Multiple Thicknesses and Ply Counts:
    • 1/2” (15/32) thickness – 4 plys
    • 3/4” (23/32) thickness – 5 plys

 

To ensure ACX plywood can withstand the rigors of exterior weather, it is important to properly finish the surface.

  1. Surface Preparation: Sand the plywood surface smoothly to remove any rough spots and dust, ensuring the finish adheres properly.
  2. Sealing the Edges: Apply a weatherproof sealant or epoxy to the edges, which are more vulnerable to moisture penetration.
  3. Priming: Use a high-quality exterior primer suitable for plywood to create a good base for paint or stain.
  4. Waterproof Coating: Apply a durable exterior-grade paint, stain, or weatherproof sealant designed for outdoor use. Use multiple coats as recommended for maximum protection.
  5. UV Protection: Opt for finishes that contain UV blockers to prevent sun damage and color fading.
  6. Regular Maintenance: Periodically inspect, reseal, or repaint the surface to maintain weather resistance over time.

Following these steps helps protect ACX plywood from moisture, UV rays, and temperature fluctuations, extending its lifespan outdoors.

 

For a more durable and long-lasting exterior finish on ACX plywood, consider these additional treatment options:

  1. Coat with a wood preservative:
    • Treating the ACX plywood with a wood preservative on the unfinished plywood prior to coating with a primer or another coating will enhance resistance to moisture, fungi, and pests, increasing longevity. We recommend using Q8 log oil or a Woodlife product.
  2. Marine-Grade Epoxy Coatings:
    • Use marine-grade epoxy on all exposed surfaces and edges to provide superior waterproofing, UV resistance, and structural integrity.
  3. High-Quality Exterior Paints or Stains:
    • Apply UV-resistant acrylic or oil-based exterior paints or stains with added sealants to ensure durability and weather resistance.
  4. Elastomeric Sealants and Coatings:
    • Use elastomeric coatings on the surface to bridge small cracks, accommodate expansion, and provide continuous waterproofing.
  5. Polyurethane or Urethane Topcoats:
    • Applying a durable polyurethane or urethane topcoat adds UV protection, waterproofing, and abrasion resistance.
  6. Edge Sealing with Epoxy:
    • Seal all edges and cut surfaces with epoxy to prevent water ingress through the core or edges.
  7. Additional Protective Barriers:
    • Install overhangs, flashing, or waterproof membranes to shield the plywood from direct exposure to rain, sun, and moisture.
  8. Regular Maintenance:
    • Periodically inspect the finish and reapply protective coatings as needed to address wear, UV damage, or cracks.
