Intergrain UltraPrep mould killer is an 800g timber preparation product that kills and lifts mould from exterior timber before it is oiled, stained or repainted.

  • Size: 800g
  • Range: Intergrain UltraPrep (timber preparation)
  • Use: Mould removal on exterior timber

Coating over live mould is wasted work — it keeps growing under the new finish and breaks it down from beneath. Treat decks, cladding, screens and outdoor furniture first: apply per the pack directions, allow it to work, then scrub and rinse the surface clean. Once the timber has dried, it is ready for the Intergrain coating system to go on and stay on.

More about this product

Intergrain 800g Ultraprep Mould Killer is a specially formulated solution designed to effectively kill and remove mould from timber surfaces.

This product is intended for use on both coated and uncoated exterior timber, providing an active mould killing life of 6 hours once diluted. To use, mix 800g of the powder with 8L of water, ensuring it is fully dissolved. Apply the solution with a stiff bristle brush, allowing it to sit for 15 minutes without drying. Rinse thoroughly with high pressure water for optimal results. Any remaining mould can be treated by repeating the application process. It is important to use the diluted solution within 6 hours and dispose of any leftovers safely down a drain.

Brilliant Aussie deal

Been buying Intergrain gear for years and this is one of their better ones. The Intergrain 800g quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
