Lumber & Plywood Preservative Treatment Products

Hoover Treated Wood Products is a leader in the preservative-treated wood industry, offering Dura-Guard, CCA and COP-8 products for above ground, in ground, fresh water and EPA applications.

CCA PRESERVATIVE

Hoover CCA preservative helps protect lumber and plywood from decay and termite attack. Treated in accordance ASTM D1625 and ASTM D1760, Hoover CCA preservative-treated lumber is southern pine, mixed southern pine, Hem-Fir, Spruce Pine Fir or other recognized species, kiln dried after treatment (KDAT) to a moisture content of 19% or less. Hoover CCA preservative-treated plywood is composed of softwood species, glued with waterproof adhesives and kiln dried to a moisture content of 18% or less. The resulting treated wood is lightweight, pre-shrunk, clean and strong.

Features of Hoover CCA treated products include:

• Wrapped in waterproof covers to remain clean and dry
• Reduced moisture content adds strength and stability
• Light and easy to handle
• Pre-shrunk for reduced shrinkage
• KDAT process permits quick finishing after installation

COP-8

Cop-8 is a proven fungicidal water-repellent preservative for above-ground lumber and plywood applications. Its active ingredient is copper-8-quinolinolate, carried in a light petroleum solvent and applied to wood under pressure. Cop-8 is approved by the U.S. Food and Drug Administration for contact with agricultural food products and can be used in truck beds and refrigerated storage structures. It is also suited for above-ground exterior applications, such as playground equipment, picnic tables and decking.

Features of Hoover COP-8 include:

• Resists warping and splitting
• Withstands exposure to rain and sun
• Does not change the color of the wood, other than darkening from the moistening effect of the oil-borne treatment
• Effective for southern pine, Douglas fir, western red cedar, red oak, keruing (apitong), kapur, white oak, hemlock, redwood, white fir and other wood species

DURA-GUARD®
