Why Choose Dindas LOSP Timber Treatment?

No Drying Process Required

Unlike water-based pressure treatments, our LOSP treatment does not increase the timber’s moisture content. This means no additional drying is required post-treatment, allowing the timber to maintain its original size, shape, and strength grading.

Fast Turnaround and Cost-Effective

Our LOSP process enables rapid order fulfilment, eliminating the need for large storage and drying facilities. This translates to a reliable, cost-effective solution for our customers.

Dimensional Stability

The consistent moisture levels maintained during and after LOSP treatment ensure dimensional stability, making it ideal for the precise tolerances required in engineered timber products.

Versatile Applications

Our treatment varies in colour, with the H3 option being the only clear, durable choice on the market. This exclusive clear coat preserves the natural tones of timber, making it perfect for visible applications.

Partnership for Excellence

Treatments used by Dindas are supplied by our chemical partners, Koppers Performance Chemicals. We benefit from their regular specialist audits, ensuring the quality and consistency of the treatments applied to our wide range of products.

By choosing Dindas Australia for your LOSP timber treatment needs, you invest in a solution that combines tradition, innovation, and unparalleled expertise.

From architects and building designers to landscapers and homeowners, you can rest assured that when specifying timber from the treated range for all structural, outdoor, and above-ground building needs.

Appearance

Dindas Australia’s standard LOSP timber treatments feature a coloured dye coating for treatment range identification and tracing purposes. For optimal results, it is recommended to use acrylic coating options, as the dyes can bleed through many paints and decorative finishes.

Water Repellent

All LOSP Timber treatments offered by Dindas Australia feature a specially formulated water-repellent resin and wax system. This solution reduces water absorption during construction, enhancing the timber’s dimensional stability.

Coatings and Sealants

Always refer to the label of your finishing product and follow the manufacturer’s instructions for optimal results.

Dindas LOSP treated timber is compatible with most industrial alkyd-based joinery primers once the timber has fully dried after treatment.
For a long-lasting finish with alkyd-based primers, ensure subsequent on-site preparation and top coating are performed as recommended by the manufacturer.
Note that some acrylic primers may not be suitable for timber treated with LOSP preservatives. Consulting the paint manufacturer or a qualified agent is advisable.
LOSP timber treatments work well with most sealants and mastics, provided manufacturer instructions are followed.
For interior applications, if the timber becomes wet during construction, it should be allowed to dry before being covered or enclosed.

Our commitment to customer satisfaction and product excellence ensures that you always get the best results.

Nails, Fasteners and Fittings

You can confidently use fasteners and hardware that comply with building codes for their intended use. LOSP H2 treatments do not increase the corrosion risk of fixings and fittings, ensuring safety and durability.
