APPENDIX A

WOOD PRESERVATION TREATMENT

American Wood Protection Association Book of Standards (AWPA) 2009

P25-8 (Replaces former P5 and C31-95) – Pressure Treatment with inorganic boron

The Contractor shall strictly adhere the following preservation treatment proceedures on all wooden components, (Laminated masts shall have a separate and different preservation procedure). All wood surfaces that have been cut, sanded, penetrated or perforated by the

Contractor shall have the interior surfaces of any hole, perforation or the area sanded or area cut swabbed twice (2x) with a fifteen percent, (15%), solution of Tim-bor wood preservative or COR approved chemical equivalent and allowed to dry prior to other coatings and installation.

TIMBERS, BEAMS AND SOLID (Grown) SPARS:

As soon as possible after the tree is cut the log should be treated at both ends and at all bark scars with a 5-10% solution of Tim-bor .

Prior to shaping:

After the bark is removed, apply a 15% aqueous solution of Tim-bor to all wood surfaces by brush or spray until wood surface is thoroughly wet, at a rate of approximately 5 gallons per

1000 square feet of surface area. If shaping will not begin within one week, the entire log should be wrapped and sealed until milling begins.

Following shaping:

Immediately following all shaping procedures apply 15% aqueous solution of Tim-bor to all wood surfaces by brush or spray until surface is thoroughly wet, at a rate of approximately 5 gallons per 1000 square feet of wood surface area. Before surfaces are allowed to dry, wood is to be thoroughly sealed inside a waterproof barrier material such as plastic wrap, and delivered to

Hi-Bor clear borate pressure treatment facility as soon as possible. Spars to be treated per

Hawaii construction standards with clear borate treatment, then sealed inside a waterproof barrier material for shipment.

LAMINATED SPARS:

Following shaping:

Immediately following all shaping procedures twice (2x) apply 15% aqueous solution of Tim-bor to all wood surfaces by brush or spray until surface is thoroughly wet, at a rate of approximately

5 gallons per 1000 square feet of wood surface area. Following second application and before surfaces are allowed to dry, wood is to be thoroughly sealed inside a waterproof barrier material for shipment.

Inorganic Boron (Borax–Boric Acid)

Borate preservatives are readily soluble in water and highly leachable and should be used only above ground where the wood is protected from wetting. When used above ground and protected from wetting, this preservative is very effective against decay, termites, beetles, and carpenter ants. Inorganic boron (SBX) is listed in AWPA standards for protected applications such as framing lumber. The solid or treating solution for borate preservatives

(borates) should be greater than 98% pure, on an anhydrous basis (AWPA P5). Acceptable borate compounds are sodium octaborate, sodium tetraborate, sodium pentaborate, and boric acid. These compounds are derived from the mineral sodium borate, which is the same material used in laundry additives.

Preservative source:

Tim-bor source and application information can be obtained from U.S. Borax Inc, or online.

Precautions:

Disodium octaborate tetrahydrate (Tim-bor) presents little or no hazard to humans and has low acute oral and dermal toxicities. However, read and follow instructions and precautionary statements on label and MSDS.

Preservation solution preparation:

To prepare solution, hot water should be added to the mixing tank to about 80% of the final volume of solution required. While agitating, add 1.5 pounds of Tim-bor for each gallon of treating solution. Use of warm or hot water (120-150 degrees F) will aid in dissolving the product.

All requirements and recommendations of the utilized Paint Manufacturers Representative or

Product Literature. Paint to be applied to meet the mils dry film thickness (MDFT) identified by the paint manufacturer or the paint manufacturer’s representative.

Wooden Components

Surface Preparation:

• Previously painted surfaces shall have all loose coatings removed to either bare wood or to a point where the paint is thoroughly bonded to the wood.

• Edges where old paint meets exposed wood or lower coatings of paint shall be sanded and faired presenting a smooth transition from bare wood/previously coated surfaces to topmoast prepared coating.

• Bare wood shall receive one (1) coat clear wood sealer (Z-Spar S-120 Wood Sealer or

COR approved equal)

• All wooden surfaces shall receive one (1) marine alklyd primer coat at (Z-Spar 105

Undercoat or COR approved equal). Prime coat may be tinted with topcoat paint.

Metal Components

All metal components that are to be used (new or old) shall be sand blasted to an SP6 specification and then inspected for cracks, signs of fatigue or level of deterioration. The inspection will inform the next steps, whether they are galvanizing and paint or repair or replacement.

Surface Preparation

• SSPC-SP6 Blast Cleaning

• Hot dipped galvanized as specified above.

• All surfaces shall be coated with one (1) coat anti-corrosive paint at 5mils dry per coat.

(Intershield 300V or COR approved equal)

Topcoats – Wood and Metal

• All surfaces shall be sanded to receive two (2) semi-gloss marine alklyd coatings at

MDFT recommended by the Paint Manufacturer’s Representative or product literature.

• First topcoat shall dry sufficiently to reach minimum hardness specified by the manufacturer before sanding or overcoating.

• Mil Film Dry Thickness (MDFT) shall be measured after each coating.

• First topcoat shall be sanded, cleaned and wiped with denatured alcohol (or COR approved equal) to accept second topcoat.

• Areas found to contain runs, overspray, inadequate film thickness, roughness, impregnated dust or grit, or any other film or surface preparation irregularities are to be repaired or re-coated as directed by the COR at no additional cost to the government.
