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

Black, easy to apply, can be messy
The price is good and delivery was quick. The sealant tube is as easy to use as any other sealant tube (though you'll need to provide your own nozzle). Adhesion is good but not great, so you can get some stray blobs, and with the black dye those blobs can soon make your clothes a mess... be careful out there!

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.

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.

Great range of sealants.
I'm a convert to dowsil sealants. Wide variety of elasticity, huge range of colours for matching what you're working on, good to apply. I used this one finishing around a rubber floodseal for my garage door. Finished the corners by the doorframe.
