Staining a New Deck

All timber needs to be weathered before you stain it. Darker coloured timbers or gum timbers in particular need to be left for about 4-6 weeks, so the excess tannin and gum can leach out. We have a variety of products to expedite this process, such as Wax & Oil Remover or Chlorite. We recommend diluting them 3:1 with water and washing down the timber. Lots of tannin and resin should wash out. It's worth scrubbing the deck to help drag out the deeper tannin and resin. Once you're happy with what's been removed, rinse the deck off with fresh water and allow to dry. Depending on your preference, apply 2  coats of Exterior Oil Acrylic or Rich Wood Oil to the decking. Allow 8 hours between coats for the Exterior Oil Acrylic, and if possible, 1 week or more between coats for the Rich Wood Oil. A colour will always out perform a clear as pigment is a UV filter.

Recoating A Deck or Garden Furniture

If the deck or furniture is irregular in colour, with black and grey patches, it's best to use Grey Away or Grimes & Sons Timber Bleach. It should disinfect the timber and balance the colours. Soak for 5 minutes, scrub with a stiff bristled brush, then rinse with water. Soiled material should wash straight off, and try to avoid getting it on plants. Reapply with existing coating system. Precoat the raw or most weathered areas first. Apply heavier coats there, and thinner coats on the sheltered, protected areas.
