Ronseal Total Wood Preserver does not provide waterproofing protection.
Before You Start
Make sure the surface you’re protecting is clean, dry and free from any coatings like paint, varnish or stain. You’ll need to strengthen any decayed wood with Ronseal Wet Rot Wood Hardener. Once this has hardened, you’ll be able to repair the wood with Ronseal High Performance Wood Filler.
Using your preserver
Give the tin a good shake. You can either brush, spray it on or dip apply. For the end grains, we’d recommend dipping to make sure that the preserver completely soaks into the wood. You’ll need to add at least two coats, waiting 24 hours between them. If you need to carry out any repairs or gluing, wait until the second coat is completely dry.
Note that Ronseal Total Wood Preserver is not compatible with Ronseal Sprayers.
Remove as much preserver off your brush as you can then clean with a brush cleaner. Don’t empty any left over preserver into drains or watercourses. Your local authority may have special ways to get rid of unused paints.
How to recognise dry rot
Dry rot might appear as white, fluffy, cotton wool like growths or in white or grey sheets. You may also find grey or white branching strands, up to 6mm wide spreading on brickwork or behind plaster. Rusty red, pancake shaped, fruit bodies can also mean that you have a dry rot problem. Wood under attack from dry rot shrinks and splits in large brick shaped pieces across the grain and is dry and brittle.
How to recognise wet rot
Wet rot is a fungal attack and can cause the surface of the wood to darken. Decayed wood splits along the grain and smaller cubes of wood are formed as a result. The wood may also become soft and spongy. Thin, brown branching strands of fungi may form on the surface of the timber under attack.
How to recognise insect attack
Insect attack can be recognised by small, round flight holes on the surface of the wood or by tunnels in the wood. New holes will show clean, fresh timber inside them and fine, gritty powder can be seen on the surface or beneath the site of activity.
