Can I paint after applying Bone Dry?

You cannot paint the surface after using Bone Dry because the water repellent in the product won’t allow the paint to adhere.

What is the dilution rate? 

Dilute Bone Dry 1 part to 2 parts water for the 5L container. Ensure that the surface is clean. This will treat up to 100m2

Can Bone Dry be used on cane?

Non treated cane that is porous is fine to treat with Bone Dry. Do a test underneath first to check the finish. Keep in mind that it cannot be painted after the Bone Dry treatment.

Can Bone Dry be used on sandstone?

Bone Dry can be used on all varieties of sandstone very successfully esp Hinuera and Oamaru stone. It makes the stone impervious to water, but not obvious to the eye.

Will Bone Dry seal a surface that was done some time ago?

It is best to do a water test to see if it is still porous. If it is - you can. If it’s not porous, you can’t.

Does Bone Dry leave a 'wet look'?

No. It’s designed to penetrate into the porous surface & you won’t know it’s there. All surfaces retain their light, refreshing, dry appearance even when wet.

How do I clean up after application?

Wash your sprayer or brushes out with water. If it dries in the nozzle, soak the nozzle in methylated spirits. It is a water soluable product.

How do I remove overspray from windows?

Use cotton wool soaked in methylated spirits.

How do I use Bone Dry on canvas/ awnings?

Dilute Bone Dry 2 parts water to 1 part Bone Dry and apply to the clean dry canvas awning, umbrella, dodger or sail cover.

Is Bone Dry toxic to plants & animals?

Bone dry is non toxic and therefore more environmentally friendly. It won't harm plants or animals and it cleans up in water. Odourless - no solvents or volatile components.

Is Bone Dry OK for timber?

  • You must firstly ensure that your deck has totally been cleaned up (using Wet & Forget or Rapid Application) before you apply Bone Dry. Bone Dry is good for timber because the water just jumps off the surface.
  • On timber retaining walls, it stops them going black from biological growth.
  • Timber decks also benefit as it slows biological growth and helps prevent staining from spills such as BBQ fat etc.
  • External cedar weatherboards can be sealed with Bone Dry and it certainly won't peel like a traditional “film forming” coating e.g. varnish. Only apply one coat of Bone Dry for this application.
  • NEW DECKING Just make sure it “weathers” before application as the natural resins in the timber when newly laid will prevent the Bone Dry soaking in. Minimum wait is 3-4 months.

Is Bone Dry OK for paving stones?

Absolutely!! It stabilizes sand joints between paving stones to prevent paving movement and erosion. It's not slippery when applied to paving stones.

Does Bone Dry help with sand stabilization?

On paving, use 1 part Bone Dry to 1 part water. Flood surface and squeegee excess off the surface and into joints.

Is Bone Dry water based or oil based?

It is water based for easy clean up.

What are the active ingredients in Bone Dry?

It contains a combination of an acrylic emulsion and a silicone resin. The acrylic seals the pores and the silicone repels the water.

What garden spray can I use for applying Bone Dry?

Apply Bone Dry from the same garden spray unit as you use for your Wet & Forget

How long does Bone Dry last?

Between 3-5 years. You can always check by pouring some water over the surface. If it gets absorbed in, then you need to reapply. If it repels the water - you are OK.

How does Bone Dry work?

It slows the biological growth of moss, mould and algae by keeping the porous surface a lot drier. Bone Dry is a unique, water based, polymer dispersion which is designed to help seal concrete paths and paving blocks. When used in conjunction with Wet and Forget for the pre-treatment cleaning process, Bone Dry will seal the pores and stops dirt and water from penetrating the surface thus slowing green algae and black mould from growing back again too quickly.

  • Only apply one coat!
  • Ensure dilution rate and application are followed exactly.

    Exceptionally porous surfaces may need a second coat. Test a small area to ascertain if the surface still absorbs water after allowing Bone Dry to dry for 1 hour. For best results the second coat should be applied between 2 - 4 hours.

    Apply to large areas with a garden sprayer or use a brush for clay pots or small items.

I am writing to let you know about your product, “Bone Dry”. I live on a farm with a pine deck that faces south.It is probably 8 years old now. At the beginning of last summer I desperately needed to clean it as it had gone very black and slippery. I used Wet & Forget to clean it and was amazed at how it came up! Just like new almost.

But, I was also aware that facing south and being cold and wet, the mould was likely to come back again. I went online and bought your product “Bone Dry”. It said it was a moisture-proofer that kept about 80 to 90% of the moisture out of the pine but that it wasn’t slippery. In fact, was hard to see once applied. We have now been through a very wet Autumn, Winter and Spring and the deck still looks as good as the day we applied the “Bone Dry”. A big thanks for a fantastic product.


Just a note about a fantastic product I used two years ago on my Kwila outdoor furniture and timber deck. The product is called Bone Dry! I had cleaned up my very , green, grotty deck and furniture and with such a lot of work wanted to try and keep it this way. A friend told me about Bone Dry as he had used it. I didn’t want a varnish or stain type finish and was assured you don’t really even see this product on the timber.

He said it would keep the timber sealed and slow down the mould and algae! He was dead right! Two grotty wet winters and the deck and furniture still look like new! A fantastic product and so easy to use, as per your instructions. Thanks from a very happy customer.
