At a Glance

  • Sizes: 1 litre / 2.5 litre / 15 litre.
  • Protects new exterior wood, against damaging effects of sun and moisture in the first 6-12 months when it is at its most vulnerable.
  • Seasonite penetrates into the wood, bonding with the wood fibres to regulate the movement of moisture.
  • One-coat application, easy clean up with soap and water.
  • 1 litre covers 5-7 m².

The effects of sun and moisture on new wood can create splitting, swelling, cupping and warping. An immediate application of Seasonite will protect the wood against fading and control the movement of any moisture in and out of the timber; thus minimising the potential for the wood to split, warp, cup and crack - keeping new wood looking new longer.

Unlike some new wood treatments that just sit on the surface and are easily scuffed off, Seasonite penetrates into the wood, bonding with the wood fibres to regulate the movement of moisture.

Seasonite protects pressure-treated wood, cedar, redwood and other exterior timbers including hardwoods.

Ready to use Seasonite offers a convenient one-coat application and easy clean up with soap and water.

Where to Use Seasonite

  • To stabilise new exterior wood, including soft or hardwoods; pressure-treated wood; kiln-dried timbers such as Cedar and redwood during the first year of weathering.
  • Ideal for new garden decks, cladding, fences, shingles, shakes and unfinished outdoor furniture.

Coverage / Maintenance

Number of coats recommended: 1.
Drying time (to touch): 12 hours.
Usage: exterior wood, e.g. cladding, decking and fencing. Can be used on pressure-treated wood, not suitable for Oak.
Recommended application: for best results surfaces must be clean, dry and free of dirt, grease, grime and mildew.

Approximate Coverage

5-7 square metres per litre with one coat on smooth wood.

Coverage will vary depending on the type of wood, age and surface texture.

Maintenance Cycle
