Sika Black Jack 905 All Weather Roof Coating, Black, 5 Litre

Exceptional packaging, product works well too.

Used the liquid weather coating on summer house, the product was easy to stir in the tin, I used a roller for most of the work, finishing hard to reach places with a paint brush, the finish was brilliant, very low odor, but still wore a mask,drying time very quick but with plenty of time to apply the product, very good value for the money

Will have to re-order as tin arrived damaged but based on previous use of this roof coating I haven't found anything yet on the market which does such a good job for such an affordable price.

Having put it to use, it does what you expect, makes a weather proof coating. It seems to have done a good job at sealing as I have not detected any leaks from a previously leaking tin roof that was full of micro holes, so a good performance. I would recommend you give this a VERY good stir as the fibre-like additive sinks to the bottom of the tin in a thick mass. The addition of this additive (some kind of fibrous substance) is a great idea as it helps fill all manner of holes and cracks well, it makes a nice looking finish too. It has a subtle odour when wet but nothing detectable once dry. Easy to use and apply but, as you would expect, can get a little messy so gloves and old overalls are recommended. It came well packaged in a supported box and had retaining clips on the lid plus a plastic cover around the tin. Just as well as it was subjected to some abuse from the courier and although bashed and dented, only a little was spilled and that was contained in the plastic cover. 10/10 for packaging, 2/10 for the courier.

Used this as double protection for shed roof, painted this on, then used shed roof felt. Absolutely no leaks.

Delivered without a problem. Found easy to paint on. Dryed out no problem.

Just the job

Very good must mix well preferably with a drill attachment but used a small roller and went on easy didn't fix my problem but second coat may
