Can Wood Preservatives be used indoors?

Wood Preservatives are not intended for indoor use. These products are intended for outdoor use only on decks, fences, picnic tables, or on any uncoated or pressure treated wood.

Can I use Wood Preservatives on wood that has already been treated with a varnish, clear coat sealer, or any other type of coating system?

Wood Preservatives should be applied before treating with stains and water sealers and cannot be applied over new varnish or paint. The preservatives would not penetrate into the wood enough to be beneficial. The only exception is if the stain or water sealer is very old (more than 5 years), then Wood Preservatives can be applied without risk of damaging the old finish.

What is the difference between Copper II and Clear Wood Preservative?

Copper II is a bright green preservative based on copper naphthenate as the active ingredient so it is best used where the greenish tinge on the wood is not a problem or a dark paint will be used over it. It cannot be painted over with pale colours and will show through transparent stains. Copper II provides slightly better protection than clear preservative so it is often recommended for wood in contact with soil or to reduce maintenance. Clear preservative is based on Zinc naphthenate and provides invisible protection. It is ideal where the natural colour of wood is desired or where the wood will be painted with light coloured paints or transparent stains.

When will my Green Wood Preservative stop smelling? Can I paint over it?

Most Wood Preservatives dry in 2 weeks or when the temperature reaches roughly 28°C. Once dry, the odour will dissipate. Green Wood Preservative could bleed through paint, so use a dark colour to prevent discoloration or refrain from painting all together.

Can I paint over Clear Wood Preservative once it is dry?

Yes. It is called clear, paintable preservative because it will not bleed through paint. Even light coloured paints can be used successfully.

How often should I reapply Wood Preservatives to previously treated wood?

Reapply Wood Preservatives every 3 to 5 years in normal conditions and more frequently when conditions are more severe, such as shaded damp areas or those exposed to prolonged direct sunlight.

How long does Clear Wood Preservative last?

Under normal conditions, Clear Wood Preservative lasts approximately 2 to 3 years.

What is the water repellency rating of your Copper II or Clear Wood Preservative?

We do not recommend using a wood preservative as a water repellent. Recochem does have a product called Water Repellent item 13-754 that is excellent for providing water repellency.

What is the best method to apply Wood Preservatives? Can I use a spray gun?

Always use a paintbrush or roller to apply Wood Preservatives. Please note that government regulations prohibit the application of Wood Preservatives by a spray gun. Use a brush or roller.

Can I reduce the odour associated with Wood Preservatives?

Treat the wood outdoors, and take a break if you find the odour is strong. You can also make the odour less noticeable by mixing an ounce (ml) of aromatherapy essential oil (cinnamon or bergamot) into the preservative.

Are Wood Preservatives toxic? Can I touch the wood after it is applied?

Wood Preservatives can be touched once dry without any harmful side effects. Wood Preservatives are mainly toxic when wet. Once dry, they are safe for skin contact.

Do any of your wood preservative products contain arsenic?

No. Arsenic is sometimes found in the chemicals used to treat pressure treated lumber. Wood preservative applied by brushing on do not contain arsenic.

Once treated with Wood Preservatives, is the wood the same as pressure treated wood?

The result is similar, but pressure treating provides deeper penetration of preservatives into the wood.
