Everbuild Black Jack 905 – All Weather Roof Coating – Solvent-Based – Fibre-Reinforced – Fast Drying – Weatherproof – Black – 5 Litre

Provides good coverage and durability. Applied it last week (in a cold, wet, grim January) and creates a strong, weatherproof seal, making it a great choice for protecting roofs. Straightforward to apply, just give it a good mix before you start.

Brilliant product....stopped my flat roof garage leaks with a couple of coats...easy to apply...good price too...nice size tin to handle as well...

Using on my garage roof sealed the part I have done need to finish when dry.

Great go sealing fibre roofing sheats

Five stars for the product itself. It's a quality product, easy to use and does exactly what it's supposed to do, as do all Everbuild products.However, zero starts for the delivery and I am in full agreement with other reviews. The box, heavily wrapped with 'Fragile' tape was battered and round. The 2 cans themselves were even more battered and almost square. I had to knock one of the tin bases back into shape as it was impossible to stand the can up. The other tin had a pinhole leak on a highly damaged bottom weld, probably the viscosity that stopped a worse leak.I shouldn't have been surprised by this as the courier is one of the worst there is.Sellers ought to show which courier they use so that buyers have a choice as to whether to risk their purchases in the hands of incompetent and apathetic carriers.

Easy to use and did what I need we d it to do, good value for money, a little goes long way. Stopped the leak. Fit for purpose.

Might well be good stuff, but is a very messy substance to use, beware. Best to wear some thin protective gloves as it drips from the brush very easily. Did some flat roof work and some shed roof work. So far it’s protecting well (after a month on) and some heavy rain recently. So probably good but as I say make sure you protect the floor, if you need to and your hands otherwise you’ll need a lot of white spirit! It comes across as a thin layer, so I put three on but appears to give a decent finish.

Arrived on time very happy with product.
