Product information

Product information

This deep mahogany interior varnish from the Ronseal Interior diamond hard range can be applied to interior using a brush. The varnish dries in just 20 minutes and will cover up to 24 m² per litre on average.

  • Guarantee - Statutory
  • Surface Preparation - Ensure the room is warm and ventilated. To prepare the wood for varnishing, give the surface a wipe down with a cloth and white spirit to remove wax, grease, dirt and oil. Use 120 grit sandpaper to give the surface a quick sand and smooth out any rough patches. If the wood has an old coating on it, sand away the peeling, loose and flaking bits so the surface is even. Let the dust settle and wipe it away with a damp cloth. Leave the wood to dry thoroughly before varnishing.
  • Instructions for Use - Give your varnish a stir, and test the colour on a hidden patch to make sure you’re happy with it. It may darken your wood slightly but it should bring out its natural colour. If you’re happy with how it looks, apply an even layer of the varnish painting in the direction of the woodgrain. Wait one hour for the coat to dry. You will need two to three coats for complete coverage and protection. Before you apply your final coat (whether that’s the second or third), sand down the surface and wipe the dust off with a cloth. This will help your final coat stick smoothly and will give you a perfect finish.

Good and easy to yse

Very easy to mix, use and store. Patience is needed as it's not a "one coat" job. But it does turn out the colour it advertises. Eventually. It's quick drying too. And even after 5 coats (3 on top of table, 2 on underside and legs) there's approximately half a tin left.

Does what it says on the tin

I bought this to refresh the windowsills and skirtings in my conservatory. I was sceptical about the colour as it looked pink but it’s dried to a lovely mahogany satin finish. The coverage is excellent as I’ve used two coats on a large area and used about a third of the tin.

Super Product

I used this product this week on a staircase. The product provides great coverage and adhesion. Drying time was excellent (although applied on a very warm day) The satin finish gave a great sheen. Overall I would highly recommend this product.
