Thompsons 10 Year Roof Seal Black 4Ltr
Very easy to apply, and went off very quickly. Grey when applied, dries black, but appears grey when wet - something to bear in mind if trying to match to an existing colour

Heavy rain - buckets dry!
I have a large gently sloping garage roof covered with corrugated probably asbestos! I have had to strategically place buckets beneath several areas in the 4 years I have lived here. So far, I have used 2 4l cans so to cover about 3/4 of roof and after a night of heavy rain, my buckets are all dry. However, a slight new leak has appeared under the section of yet untreated roof, so the indications are that this product has performed magically. It is very easy to apply but 1 litre has only covered about 1 sq m so it has worked out quite expensive - at this rate will need another 3 cans to finish 1st coat and apply a second.

Good stuff, shame about wait
Great stuff, BUT it definitely needs the second application written on the can - when the first coat dried, I could see pinprick holes through it - perhaps because it's waterbased, and when used on a roughcast finish it doesn't penetrate properly. The title refers to the fact that you do need every minute of the 6 hours quoted as drying time prior to a second coat.

this is exceptional, i never expected this to work that well but after 2 coats it sealed a small leak in the extension roof, just brush it on and let it dry
