PRIMED PINE
TKB H3 Primed
The TKB H3 Primed range of versatile exterior timber products is widely used by builders throughout Australia. The products combine strength and durability, with the enduring character and beauty of timber.
TKB H3 Primed is used for structural timber, and timber cladding. It is also widely used in exterior structures such as pergolas, decks, verandas, porches and balconies. The range includes laminated beams and posts, fascia boards, timber mouldings, and weatherboards. A complementary range of hand railings, stair railings and balustrades is available.
TKB H3 Primed is manufactured from radiata pine finger-jointed for defect-free strength and straightness, pressure-treated to withstand termites, borer and rot, and delivered pre-primed.
TKB H3 Primed guidelines
Storage and Handling
- Timber is hygroscopic and will absorb moisture in a damp environment and release it in a dry environment. If timber absorbs moisture, some dimensional swelling will occur.
- To avoid moisture damage, store your TKB H3 Primed product in a dry environment away from damp ground until use.
Installation
- TKB H3 Primed is a premium exterior treated timber for above ground use only. Ensure a timber clearance of 100mm above paved surfaces or 175mm above finished ground level is maintained.
Painting and Finishing
- During the installation process all exposed unprimed surfaces resulting from cut ends, mitres, notching, boring, punched nail holes or similar should be sealed with a suitable acrylic or oil-based premium exterior timber primer.
- Once the product is in place, it should be spot primed and putty applied to all nail holes.
- Ensure primed surfaces are clean and free from contaminants such as dust, grease or mildew.
- Apply a minimum of two full coats of premium acrylic exterior house paint to recommended film thickness. For a better finish and extended paint durability we recommend the application of one full coat of premium quality OIL BASED primer undercoat. Use colours that have a Light Reflective Value (LRV) of 45 to 100 (100 being pure white). Colours with a LRV of 44 to 0 (0 being pure black) progressively generate extreme surface heat when exposed to direct sunlight and can cause resin bleed, shrinkage, distortion and cracking. It will also reduce the service life of the paint coatings.
Maintenance
- Paint system longevity depends largely on the environment and quality of the original paint system. A quality paint system should last in excess of 10 years.
- We recommend a gentle annual washing of TKB H3 Primed. Washing, especially under eaves and overhangs, helps remove marine salts and other contaminants that have a detrimental effect on the long term life of the coating and substrate.
- When maintenance is required use premium primer and undercoats followed by the original topcoat.
Made to Standard
- Please refer to the Building Code of Australia guidelines or your local building authority/council to ensure correct construction practices are followed.
