Great product 👍 Awesome decking se
⭐️⭐️⭐️⭐️⭐️ Brilliant for Decking – Seals and Protects Perfectly! I'm currently in the middle of building a deck, and I bought this Everbuild Black Jack 901 Bitumen Paint to seal and protect the deck joists and posts before installation — and honestly, I'm seriously impressed. The coverage is excellent. A single 5L tin went further than expected — it goes on smoothly and dries to a tough, durable coating. It sticks really well to the timber and gives me real peace of mind knowing that the structural parts of my decking are protected from moisture and rot. Especially in the UK where the weather is unpredictable, this is a game changer for long-term durability. I also liked how quickly it dries for a bitumen-based product. It’s thick but manageable, and I was able to get two good coats on without waiting all day. It’s perfect for anyone wanting to do a job properly — especially if you care about the longevity of your project. Highly recommend for anyone working on decking or any timber that will be exposed to the elements. Would definitely buy again and already looking at other Everbuild products to use on future DIY projects.

Everbuild Black Jack Bitumen Paint. It's good and it certainly does the job.
If you want a liquid mastic that will protect a surface from water ingress, you'll struggle to get better than this stuff. I wanted to waterproof the part of some timber posts which would end up below ground level before they were installed. Although painting the Everbuild Black Jack Bitumen Paint onto rough timber isn't as easy as painting gloss paint, if you just switch off your brain and get on with it, the end result is worth the hassle. Try to keep it off your hands and clothes as it is messy. The consistency is fortunately not golden syrup level but a thick semi liquid which, if applied with a loaded brush, has a good covering power, you need to make sure you've got a ground sheet of sorts to catch the odd drip or have some white spirit handy to clean up the mess. I'm going to try some on my wheel barrow where the paint has flaked off, got to be better than it is at present. I've used other Everbuild products in the past and their Black Jack Thick Mastic sealer for roof repairs or tanking is worth a thought as well. All in all, if you want to waterproof your timber, get some, you won't be disappointed.

Waterproofs
This is a good product. I use it on the felt of the roof on my garden shed to waterproof as well as around my drain which has a small crack which it seals. Application is easy with a brush as long as you take your time

Does the job well
Used this product before for the lower third of fence posts on the allotment, a couple of coats to give a much longer life span. Probably the best packaged item I’ve ever purchased, completely secured in purpose made boxes leaving virtually zero chance of spillage. Highly recommended company and product.

First time user, easy to apply, single layer was all good. Smells really bad. It wasn't that bad to get off my hands. Do suggest gloves.

utilisé pour reprendre l'étanchéité en pied de mur et caniveau de pluvial, le produit fait le job avec un temps de séchage rapide, produit suffisamment liquide pour une utilisation facilitée dans l'application ainsi que les finitions
