Refer to the PDF flowchart for a visual of the steps below:

1. Preparation:

• If new:

  • Wash thoroughly using Resene Timber and Deck Wash (D813) or Resene Bio-Cleaner (D817)

• If weathered:

  • Treat Moss and Mould using Resene Moss & Mould Killer (D80).

  • Wash using Resene Timber and Deck Wash if unpainted or previously stained and Resene Paint Prep and Housewash (D812) if previously painted.

  • Resene TimberLock (D48) if unpainted or Resene Quick Dry (D45) primer if spot priming.

2. Topcoat:

• Apply 2 coats of Resene Lumbersider Low Sheen (D34) or Resene Lumbersider Matt (D327) standard or CoolColour

• Or 2 coats of Resene Sonyx 101 (D30) semi-gloss or Resene Sonyx 101 CoolColour semi-gloss

Notes:

• It is rare to find rough sawn timber used on new homes, however it was used extensively on older homes including many historic styles. Today you are most likely to see it used for fencing, sheds and pergolas.

• Unpainted rough sawn timber will use 30-40% more paint than flat sawn or smooth board.

• Rollers may be used to apply paint, particularly for rough sawn fence palings. Use the PAL Fence staining and painting kit. Depending on the timber profile, rolling with a Long Reach Roller is also effective.

• Resene Wood Primer (D40) is solventborne. Use on very weathered and compromised timbers. For sealing of knotty/resinous areas use Resene Aluminium Wood Primer (D46).



• Nails are usually left flush with the surface (as opposed to being punched and filled) and are simply painted over.

• Old, grey and weathered rough sawn timber is difficult to sand. Use Resene TimberLock in lieu of sanding if desired before applying two coats of Resene Lumbersider Low Sheen or Resene Lumbersider Matt.

• For most applications 2 coats of Resene Lumbersider Low Sheen or Resene Lumbersider Matt is sufficient, in particular for fencing. A third coat will provide extra long-term durability and performance over compromised timbers.

• Due to the rough profile apply Resene Lumbersider Low Sheen or Resene Lumbersider Matt, which have the added benefit of being self-priming. Or apply Resene Sonyx 101 semi-gloss if a more cleanable surface is required, especially over old painted band sawn timber weatherboards.

• As an alternative to painting (new or weathered), stain with a Resene Woodsman stain after killing mould and washing clean.

• Consider using a Resene CoolColour to minimise heat retention if selecting a dark colour. CoolColours have also demonstrated improved durability over standard formulations. Look for the cc next to the colour name on colour charts for CoolColour options.
