Take a look at our blog post on garden shed maintenance, where we go into some of the finer detail behind keeping your shed in good tip top condition.

New Bare Timber

  • Ensure all wooden surfaces to be treated are clean, dry and free from dirt and debris

Previously Coated Timber

  • Any surface coatings such as paint, varnish or stain must be fully removed and sanded back to bare wood

Old Timber

  • Wood that has become decayed should be removed and replaced
  • Cut out and burn all decayed wood at least 45cm beyond the area of damage
  • Brush down the wood with a stiff broom or brush to remove any ingrained surface dirt
  • Traces of mould, algae or fungi must be removed with a stiff brush or scraper
  • Areas that have been affected by mould, algae or fungi should be treated with a suitable exterior wood cleaner prior to applying Ronseal Shed and Fence Preserver

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 to ensure a consistent colour. Avoid contact with bitumen, bitumen felt, mastics and plastics.

  1. Ronseal Shed and Fence Preserver can be brush applied or by dipping the timber into the product, and can be spray applied with a suitable solvent spray system and safety equipment
  2. Where possible, end grain should be dipped or given extra coats to ensure the best possible protection
  3. Apply 2 coats for eradication of woodworm in roof joists, floorboards, joinery and small timbers; 3 coats for eradication of dry and wet rot and insect attack in existing or replacement timbers
  4. Allow 24 hours drying time between coats

Once dry, this preservative can be over-coated with a suitable Ronseal exterior finish. When over-coating and for the best results, always follow the manufacturer's instructions on the tin at all times.

Wood treated with Ronseal preservative can be easily maintained by applying a fresh maintenance coat on a yearly or 2 yearly basis as required.

Please Note: If this product is over-coated with a clear decking oil, it will last for around 5 years. This is only if the decking oil is re-applied and maintained on a yearly basis.

Expensive but does what it says by A J Crawshay-Williams

We have extensive fencing and sheds so bought many tins of this. I covered well but must be shaken vigorously before and during use to keep the colour pigment mixed or you get varying shades

Lovely colour by Dionne Rooney

Needed more than 1 coat with brush when put on silvered aged fencing. However will last a season and will add another coat next year. Used 2 tubs for 13 panels, 1 coat, 1 side! With brush. But does look great.

Top product, just what I needed by Jonathan

Give tin a good shake first. Product soaks into the wood very well - it does not 'sit' above the surface like other finishes. For garden fences & sheds etc. it is the best I have used & the only finish I would use in the future. No hesitation in recommending. Brilliant stuff!

Good by Albert Bennett

The product seems good but only time will tell. I would suggest that you improve the cans pouring abbility and include some sort of spout .
