Frequently Asked Questions

What is Woodhouse Weatherproof®?

Woodhouse Weatherproof® is the name given to the range of Pink Primed LOSP Treated Radiata Architectural Pine designed for external construction. H3 LOSP (Light Organic Solvent Preservative) chemically treated with an organo-biocide, all Weatherproof products are recommended for building projects outside of the home such as pergolas, decks and handrails to name a few. Pink Primed with a premium industrial coating, the Weatherproof range is ready for installation and final finishing.


Where does the Weatherproof® range come from and what species of timbers is used in the manufacture?

All Woodhouse Weatherproof® is made from 100% New Zealand, premium plantation Radiata pine that has been specifically selected for the intended end-use application.  Sourced from legally managed and sustainable forests in New Zealand, all wood fibre used in the manufacturing process is environmentally considerate.

How does Kiln Drying and Finger Jointing affect the performance of the Weatherproof® range?

Kiln Drying ensures that all Weatherproof retains its dimensional integrity and does not distort when used onsite.  In simple terms the timber maintains its original size, shape and strength grading.  All radiata is dried to an average moisture content of 12-15%, ensuring the versatility of Weatherproof when used in all construction.  Finger Jointing is the process of removing defects from the wood fibre and mechanically joining the pieces of radiata into longer, straighter lengths.

Why is Weatherproof® the product of choice when designing and building external constructions?

Woodhouse Weatherproof® is a product for now and the future with a range to cater for all applications.  With products such as the F7 Structural and GL8 Laminated Beams as part of the range, the end user has options to build pergolas, decks and other designs with a durable and Pre-primed product. 

What is LOSP treatment and how does it protect the Weatherproof® range?

LOSP is the abbreviation for Light Organic Solvent Preservative, the name given to chemicals used in the treatment of all Weatherproof products.  H3 is the hazard level which relates to the amount of treatment and the recommended worse case application.  The H3 treatment level recommends above ground, exposed to the weather applications but similarly you can use Weatherproof internally also. 

What guidelines do I need to follow when handling, cutting and installing Weatherproof® products?

Ensure that all Weatherproof products are kept dry and away from moisture prior to installation to minimise the potential of degrade on-site.  It is advisable to wear the appropriate protective equipment when handling, cutting and working with all Weatherproof.  Gloves, dust mask and goggles are recommended to protect against dust and airborne particles.  Fill any nail holes and defects with a wood filler, sand and spot prime to restore the coating.   Coat any exposed timber with an in-can preservative resealer (such as Protim XJ or Tanalised Enseal) and then re-coat with a quality primer (acrylic or oil based) prior to final finishing.  The important points to remember are to reseal the protective barrier created by the LOSP and then re-apply a primer to repair the coating.

What is the long term performance of all Weatherproof® products and how do you maintain them once installed?

The Weatherproof range is a long term building product that has a limited manufacturers warranty on product durability and coating.  All Weatherproof needs to be applied with 2 coats of quality finish paint and installed with recommended fixings.  To ensure performance over time, re-coat the installed product in accordance with the paint manufacturer’s advice.  Providing all Weatherproof is maintained it will give the end user years of service in the desired application.  Details on the product warranties can be found in the Product Literature Section.

Can I really finish with 2 topcoats of finishing paint and is the coating a real primer?

Yes.  Once all Woodhouse Weatherproof® is installed, make sure that the Pink Primer is intact and has not suffered any degrade or damage while on site or during installation.  If there some areas that need attention, use a quality timber wood filler if necessary, lightly sand and apply a quality primer (acrylic or oil based) to touch up.  Follow this up with 2 topcoats of a quality paint to complete the job.  Maintain your project according to the manufacturer’s instructions.

What fixings should be used when installing the Weatherproof® range?

Use Hot dipped galvanised fixings to install all Weatherproof products.  Check the manufacturer’s recommendations and ensure that any fixing selected is non-corrosive.

How do I dispose of all Weatherproof® offcuts?

Dispose of all offcuts and waste as you would normal building waste. Do not burn/incinerate any shavings, sawdust or offcuts in open fires or barbeques. Do not use shavings on gardens or for landscaping.

How competitive is the Weatherproof® range compared to other product options?

Weatherproof is a highly competitive option for all structures where a termite resistant, Pre-primed product is deemed necessary.  With the F7 and GL8 Structural range the end user has a credible option for building decks, pergolas, walkway portals and gazebos.

Do I have to sand the Pink Primer off before painting?

NO.  Definitely not. The Woodhouse Weatherproof Pink Primer has been developed by PPG Architectural Coatings Australia Pty. Ltd., one of the leading Australian architectural and decorative paint manufacturers who market the Taubmans, Bristol and White Knight brands of decorative coatings. The pink primer is a premium grade, industrial oil based coating that has been factory applied to ensure its fit for purpose, and readiness for installation and final top coating.  Being a genuine primer, all products can be finished with 2 applications of premium acrylic, or enamel topcoat paints.
