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 an exterior mould and mildew 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.

Perfect fence preservative easy to apply (brush) by Gavin CRITCHLEY

Have used this name of product for some time. My latest purchase has the same name, but is a new formula. The odour is much reduced. The colour pigment (green in this case) is more intense and because of this requires a good shake of the tin to disperse the pigment. Goes on dark, but mellows as it dries. I used two coats on previously treated (dark brown) fence. The coverage was excellent even after one coat, but two gave a great depth of colour. A good product.

Satisfactory by Barbara Mathie

The fact that one needs to apply three coats with drying time of 24 hrs between (and then coat w a solvent varnish/oil) is a bit of a bother in NE Scotland - as is the challenge of keeping it clean of dust and sand over that period & between coats of solvent varnish/oil in an area of gusty winds blowing sand from the shore. Applying enough coats took the best part of a week, though each coat itself was speedily applied, without the top coat(s) being applied.

Lovely stuff by Mrs Karen Smith

Used this on all fences and its looks great and the colour seems to be lasting well after a year. Bought this to have ready for when it needs doing again though

Very easy to apply by David Riley

The preservative does not mark or stain the timber although a very slight darkening of the timber occurred which was expected, will not be able to comment on the affective properties of the product for a few years, note that this is a preservative and does need to be overcoated to be fully effective.

It applied easy but couldn't comment on its performance until its been down for a while by Zenyk Kohut

Applied with a brush ok but too early to tell how it performs hence 3 stars until I know a bit more. Also difficult to tell how it performs as used with other products such as decking oil.
