Rated 5 out of 5 by brown sealant applies easily, gives good adhesion and leaves a fine finish 23 Aug 2015
Rated 5 out of 5 by Sealed I purchased this on the strength of other reviews. I was not disappointed. It is easy to use, sets quickly and odour free. It easily filled the areas that I needed to between wooden door frame & masonry. Not the cheapest product but it works well. 1 Jul 2015
Rated 4 out of 5 by About the best Used this product many times and consider this about the best. Not the cheapest but well worth a little extra. Easy to apply and neaten off, good for profesional or DIY users. 2 May 2015
Rated 5 out of 5 by Good Performing & Flexible Have used the 791before & rate it highly. Easy to use, as all silicone tubes are these days, but without any odour or fumes. Brown is a good colour for 'losing' around joint edges, whereas black or white stand out. Has stood the test of time so far in the face of wind and rain, and remains very flexible which is important on outdoor uses. Would like to see it a pound a tube cheaper, but acceptable now.
