Ronseal Multi-Purpose Wood Treatment
Our Multi-Purpose Wood Treatment protects against rot and insect attacks. It soaks deep into the wood to stop future attacks – now there’s one less thing for you to worry about.
Before You Start
Make sure the surface your treating is clean and dry. You’ll also need to remove any existing coatings like paint, varnish or stains.
Using Multi-Purpose Wood Treatment
You can apply this product by either brush or spraying. If you want to apply this product as quickly as possible, give it a try with our Ronseal Pressure Sprayer. Three coats will be enough to give the ultimate protection, just remember to pay close attention
to the end grain. The second coat should be applied after the first coat has dried. If you have had to replace any timber, you should treat the new wood to make sure that you won’t have to replace it again in the future. Once the treatment is fully dried, you can carry out any repairs or gluing. In just 48 hours, you’ll be able to varnish or paint the newly treated wood.
Remove as much product as possible from your brush or sprayer and then clean it in warm, soapy water. Don’t
empty into drains or watercourses. Your local authority may have special ways to get rid of unused paints.
How to protect against wet rot
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. This will make it look better, and once it’s treated, you won’t ever have to worry about fixing it again.
How to protect against dry rot
Dry out the wood to get rid of all damp patches. You can test the wood for decay by giving it a gentle prod with a screwdriver. Take all plaster off the wall to reveal how bad the problem is, and remove all the fungal strands. 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. You should sterilise any brick or stonework that might have been in contact with the infected wood with a fungicide.
How to protect against insect attack
Three coats of Ronseal Multi Purpose Wood Treatment will prevent any insect problems; just make sure to pay close attention to the end grain.
All joints should be flooded, and treat any dry, dusty cracks. Once you’re done, wipe off any left over liquid on the wood.
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.
