Ronseal Total Wood Preservative has been formulated to provide long lasting protection against woodworm attack, prevent rot and decay and also provide protection against blue stain fungus. To kill existing woodworm infestations, use Ronseal Woodworm Killer then treat with Total Wood Preservative when dry for additional protection.

Ensure all wooden surfaces to be treated with Ronseal Wood Preserver are dry, clean and free from dirt, debris and other surface contaminates.

  • Areas that have been affected by mould, algae or fungi should be treated with Ronseal Garden Cleaner prior to preserving
  • Any surface coatings such as paint, varnish or stain must be fully removed
  • Wood that has decayed should be removed and replaced prior to application of Ronseal preservative
  • Cut out an area of at least 45cm beyond the area of damage

Always do a test area before starting any project and follow the manufacturer's instructions on the tin at all times. Shake or stir well prior to and during application, more so when using the coloured version of this product to ensure a consistent colour.

Total Wood Preservative can be brush, dipped and spray applied with a suitable solvent spray system. Please Note: If spray-applying, use a coarse spray and avoid misting. This product is not compatible with Ronseal Spray Systems. Avoid contact with bitumen, bitumen felt, mastics and plastics.

  1. Apply Ronseal Preserver to wood surface using your chosen method
  2. We recommend applying at least 2 coats, 3 for best protection
  3. Leave 24 hours between coats
  4. Where possible, end grain should be dipped or given extra coats to ensure the best possible protection

Clear Wood Preserver

The clear exterior wood preserver in this range does not contain wax so therefore only provides limited waterproofing protection, however it can be top coated with oil, water or solvent-based products.

Coloured Wood Preserver

The coloured versions of Ronseal Total Wood Preserver contain a small amount of wax that provides some water repellency and weather protection. For added protection and weatherproofing, apply a solvent-based exterior wood oil once the preservative has fully dried.Due to the wax content in the coloured version of this product, it cannot be over-coated with paints, varnishes and other coating systems.

For wooden surfaces treated with just Ronseal Total Wood Preserver, and not over-coated with anything else, a fresh coat can be applied as part of an annual maintenance program, or as required, by following the above 'Preparation' and 'Application' instructions.

Surfaces treated with Ronseal Preserver, and over-coated with a wood oil, paint or varnish do not require a fresh treatment whilst the top coat is maintained and remains intact.

Good wood penetration by Andrew Butler

good product that 'does what it says on the tin' few things to consider though: comes in a can so you'll need a paint kettle or similar to dispense into prior to use; very liquid so requires careful application (don't over load brush); stain colourant settles so mix thoroughly before application to ensure even colour coverage

The wood preservative dries absolutely clear, is easy to apply and soaks into the wood well by Angie Palmer

Ronseal total wood preservative goes on well. It does not smell too strong, but should be applied in a well ventilated area. It dries clear so can be overpainted with colour without affecting the shade.

Great clear fence treatment by Michael Brown

Always use this to freshen up and protect my featherboard fencing and gates. Does a very good job and revives the appearance of the timber too.

Probably an excellent preservative - time will tell by Chris Rotsey

Went on easily but coverage not as good as stated on the tin. I didn't realise that it was a preservative only, and does not provide any waterproofing despite being sold for treatment of external wood. This is not at all clear on a superficial reading of the product details where there is ambiguity.

A note from us...

Hello Chris,

Thank you for the feedback on this product, it would be fair to say that the clear that you purchased offers little moisture repellent properties as it contains no wax, unlike the coloured version that do. On the product page we do recommend the application of a top coat such as exterior wood oil. For more advice please call in and speak to one of our advisers.

many Thanks Samantha.

Good clear product by Alim Miah

It's very thin water like oil. Good for spraying. It brought the original colour back to my fence panels when I initially bought them. So far I've only done one coat. Three coats recommended. I probably will only do two. It's finding a calm dry day to spray it.
