Product information

Ronseal Ultimate Protection Decking Paint transforms all types and ages of decking, filling in small cracks and covering grey wood. Providing all weather and UV protection, this decking paint locks down splinters and smooths rough surfaces. To be used on all ridged or smooth hardwood and softwood decking. Apply 2 coats using a suitable brush or decking pad. It covers 10m² on ridged boards, or 12m² on smooth planed boards, is rainproof in 30 minutes, ready for the next coat in 4 hours and ready to walk on after 48 hours.

  • Guarantee - Statutory
  • Heavy duty
  • Instructions for Storage - Protect from frost
  • Surface Preparation - Before you start, choose a warm, dry day (above 10°C) and clear everything off the deck. You’ll need to give your decking a good scrub with a deck brush. This will remove dirt, loose bits of wood and any loose coatings. Then hose it down thoroughly, or better still, give it a blast with a jet wash. You need to get rid of all the dirt, if you don’t the paint won’t stick to your wood. To get the best result use Ronseal Decking Cleaner & Reviver – This will make the paint stick better and last longer. Let your deck dry fully before painting.
  • Instructions for Use - Give the paint a good stir, it’s best to use something wide like an old wooden spoon. Check you’re happy with the colour. Find a hidden part of the deck and try it. Get lots of paint on your brush. Start in the furthest corner, brushing along the length of the boards. Work on 3-4 boards at a time so you don’t get any overlap marks. If your deck has got small cracks, brush in extra paint until they’re filled. You’ll need to put on 2 coats. Leave 4 hours between each coat. After 48 hours you’ll be able to get your furniture out and use the deck. If you get any paint on yourself, wash it off with warm soapy water.

Superb

not the cheapest product on the market but after a really really good stir the product flowed on the brush covered the target area really really well and the drying time was as stated on the tin 90 minutes I've got a second coat on four hours later it poured a day later and it is perfect.

Decking paint

I have tried a few products for my decking all need 2 coats, this was not different. I will say applying was very smooth so was a lot easier than some I have used. So far it has not faded we have had hot sun, rain and storms so I am pleased with the outcome, so far although it has only been a month.
