Using Wespine Blue

Posted in Uncategorised

When treated, handled and disposed of in line with simple recommendations, Wespine Blue poses little risk to distributors, builders or homeowners. And its approval by the federal regulator, APVMA, gives you peace of mind that Wespine Blue is effective and safe.

Plasterboard Adhesion

Being a water based product, Wespine Blue has no effect on plasterboard adhesion. There are no additional requirements for fixing

Endcuts and Resealing

Endcuts, splay cuts, holes drilled for services and trenches for studs in top and bottom plates do not need to be resealed to maintain the Wespine Blue 25 year warranty. Rip sawing timber, planing faces of the timber and the like does require resealing to maintain the warranty.

Nails and Fasteners

The active ingredient in Wespine Blue, bifenthrin, is a synthetic pyrethroid, a non-metallic carbon-based compound. The corrosion potential of the product is therefore no greater than that of untreated timber. As a result, normal bright steel nails and fasteners may be used with the product for an interior non-exposed environment such as internal house framing. Good building practice should minimise the risk of moisture affecting framing timber.

Construction time and taking care of Wespine Blue

A quality plantation product like Wespine Blue needs to be treated in the same way as untreated timber. The product should be kept dry and off the ground on suitable bearers to ensure that it remains true. When Wespine Blue is built into frames it should be covered in the shortest possible time in line with normal good building practice. A maximum of three months exposure to the elements is a good guide to prevent nail and nailplate movement and reduced treatment effectiveness.

Handling

Use normal good handling procedures for timber. In particular, use gloves, dust masks and eye protection when cutting, drilling and working Wespine Blue.

Disposal

Wespine Blue may be disposed of in normal landfills or in industrial incinerators in accordance with regulations. It should not be burnt in domestic applications or allowed to come into contact with drinking water, fishponds and the like. Wespine Blue treated timber wastes and offcuts do not require special handling and can be disposed of with normal untreated timber and building wastes.

Design and Detailing

Good design and detailing practice should ensure that the building is protected from moisture and not exposed to unnecessary decay hazard. Guidelines for good building practice are given in TRADAC Technical Data Sheet 10 "Recommendations for the use of seasoned softwood framing".

Fasteners

Standard steel nails will be adequate for all fixings in terms of durability.

Ventilation and Ground Clearance

Roof, sub-floor and external wall cavities should be ventilated. Minimum ventilation and clearance requirements for sub-floors should be provided in accordance with the Building Code of Australia (BCA).

Onsite Handling and Weather Exposure

Wespine Blue treatment will not be significantly impaired by normal exposure and handling prior to and during construction. Do not store Wespine Blue treated timber in contact with the ground.

Workmanship

Good quality workmanship in all building construction is required to ensure satisfactory performance of the construction over the long term.

Maintenance

Regular building inspections for termite or borer activity and maintenance of the inspection barrier are required under AS3660.1. Maintenance and inspection will ensure that water leaks or failure of weather tightness do not expose Wespine Blue treated timber, untreated timber, and other construction materials to degradation from excess moisture or decay hazard.
