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.

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.
