Great
This is great stuff I've never heard or seen this product before i needed something for outside and the internet recommended this. I have a black outdoor junction box that was leaking in the seal originally used was coming away from the wall ideally needed to replace the box but i have that weird pebbledash insulation stuff so a nightmare to screw into hence why i got this product to seal the back of the box onto the wall and a coat around the front cap to seal it from water.

Quality sealant - A1
I bought this for a seal i needed around a black wooden outdoor unit, where I had some gaps from a pipe I had going through it. It sealed easily and was black to match the unit etc. Went off fairly fast and has remained ever since doing its job - Sealing. Cheap, easy to use and very effective. A1 Product

Hard to use but works well.
Along with most of the 791 range the sealant is very thin, for myself a novice who does sealant work a few times of year this was very difficult to work with, and hard to get a good bead. It does however have a very long working time at the expense of taking a long time to skin and cure. The last joint, only a 5/6mm bead, is still not fully cured after 48 hours. The final finish is good, flexible, but taping any porous or textures surfaces is a must, and being extra careful to not touch it for a few days is essential to a good finish.

Easy to apply and smooth
Great product, easy to apply and smooth. It wipes off of hand with ease using heavy duty wipes. I have used to seal between an asphalt roof and wood edging on a shed, where asphalt tiles on the porch meets painted wood on the house and to seal the top of a flashband against a painted pebbledash wall. I have no hesitation is recommending.

It seals.
What can one say about a tube of sealant? Does it seal? Yes.
