Finish Options

Single Coat

Our primer is a machine coated alkyd oil based primer designed as an adhesion coat for the next coat of paint. This primer does not waterproof the timber but does slow water uptake.

Radiata Pine contains tannin which can cause paint to turn brown. Our primer blocks the migration of the tannin into the paint coating minimising the discolouration of the painted surface.

Dual Coat

Applying a second coat of oil based primer gives additional durability particularly during the construction stage and reduces water uptake.

Not only does this improve the long term performance of the top coat, it reduces painters time on site, many have estimated the saving at approximately 25% cheaper than on site painting.

Treatment Types

LOSP H3.1

LOSP H3.1 is an effective preservative designed to provide lasting protection for wood products used in external situations above ground protecting against decay and insects. The timber is treated in finished form which improves its dimensional stability.

This LOSP product comes with a 25 year guarantee against fungal decay and insect attack and is water repellent to reduce general uptake of moisture.

For more detailed information about this process refer to http://www.kopperspc.co.nz/products/protim-optiumum-losp.html

CCA H3.2

CCA H3.2 is a waterborne, Chromated Copper Arsenate preservative system developed to provide long-term protection to wood exposed in exterior applications and is applied to wood by pressure treatment.

The CCA preservative is an effective fungicide and termiticide providing protection from a broad spectrum of decay fungi and wood boring insects.

MCA H3.2

Protim ® Micro is an exciting new development for LOSP treatment. Protim ® Micro is a solvent based formulation using the highly effective and widely used actives copper and tebuconazole.

Protim® Micro is ideal for use in weatherboard applications where long-term peace of mind counts.

Protim® Micro provides the long term protection traditionally associated with waterborne preservatives in a solvent system that provides the benefits of LOSP treatment with no need for kiln drying after treatment and leaves the timber with minimal dimensional change and moisture increases.

Protim® Micro is backed by a 50 year warranty and is approved for H3.1 and H3.2 in NZS3640 and H3, H4 and H5 in AS/NZS1604.1.

Grades Available

Finger Jointed

Finger jointing results in much higher quality and stronger pieces and components, while dramatically reducing waste. The two most important advantages of finger jointed lumber are straightness and dimensional stability.

Clear

Our highest quality grade which is ideally suited for uses where a long length clear finish is required.

Due to its light colour and clean appearance, Clears grade requires a minimum of processing to achieve an excellent finish. Knot free on one face and two edges.

Dressing Grade

An excellent grade for use where clear boards do not provide enough natural character.

Dressing grade still has fine appearance but features tight knots and small bark or resin pockets along the better face. Excellent recoveries are achievable as this grade can be used in its entirety.

Knots will be live on the best face and less than 1/2 of the width. Cone holes may be present in the occasional piece.
