Directions For Use

General:
HOP can be applied by brush roller or spray. For exterior applications two coats are generally recommended with particular attention to endgrain joints and interfaces (also see IN-GROUND PASTE). Clean up with mineral turpentine.

Surface Preparation:
New timber should be reasonably well weathered before application. This is particularly important with naturally oily timbers such as Tallow Wood and Jarrah. Dressed timbers, when new, should be allowed to weather for a few weeks prior to application. Thinning the product with mineral spirits or kerosene may also improve absorption and drying speed in these cases. For old timbers and remedial treatments it is essential that any decayed and weathered wood or old paint be removed prior to application.

Application:
Apply moderately as excess product will not absorb readily in most timbers.
Coverage will be generally 6-8 square metres per litre.

After Treatment:
Timber coated with HP will Initially be a strong dark green colour. With hardwoods this colour will change to rich variable brown tones, particularly when exposed to strong sunlight. This is due to a reaction of the preservative with hemicellulose which is usually abundant in hardwoods.
Softwoods, with their lower hemicellulose content, tend to remain an olive green colour which may weather eventually to light brown. Colour development is dependent on the type of timber and will be much less pronounced on heavily weathered surfaces. Drying time may vary considerably with the moisture content of the timber and local drying conditions. With dry timber and fine warm weather drying will take 2-3 days. This may be considerably longer for the second coat or with unseasoned timber or in cool weather. If possible wait at least one week before applying additional coats. Absorption and performance of the product will generally be better on rough sawn rather than dressed timbers.

Recommendations and Re-Application:
Generally, the product should be reapplied after 2-3 years. This may be shorter or longer depending on the severity of local conditions. The preservative value of the product will persist long after much of the original colour has apparently weathered away. As the treatment is a penetrating oil type, re-application is easy as the new coat can go directly over the old without additional preparation.
