How to Install Ubiflex B2 & B3 Lead-Free Flashing

[@captkremen1725]

I've found the Ubiflex to be better to use on highly profiled tiles, like the Sandtoft Olympus where lead struggles to stretch to mould to the shape. The high-tack adhesive does prevent the front springing up, though I had great results and less mess using butyl tape. (Used on a new-build, 6-bed house)

It all hangs on how good the adhesive bonds and how long it lasts if that fails then end of story. Not convinced.

03:51 With respect, the corner seems a bit messy, with a crease and with sealant blobbed down from the joint onto the flashing. Is this as good as it gets?

Same it might stick in factory conditions where it’s made but on site with dust everywhere it ain’t good

I love the fact that I have to look into crap like this instead of lead due to the fact theres a good chance lead installed at low height in a back lane will be nicked. Bring back the birch.

It creases on turns around corners, like shown in this video. It pulls out unless wedges are installed 6 inches apart. It costs just as much as a decent roll of lead. Hate the stuff

Every time its windy I've seen this slowly blow and water leak so the bonding wont stick for long

It’s shit would use it on my dogs house

[@AndrewHelgeCox]

If you dog out mortar 3cm deep on a long run and replace it with flexible sealant, doesn't that affect the load bearing capacity of the wall in question? 3cm is a good way through the width of a brick. For the loads on that run of bricks, it's like they were placed with 3cm hanging out in the air along their lengths.

Is it my eyes? - that doesn't look like 150mm to me (as per the narrative) - nearer to 225 methinks.

[@northeastcorals]

Yeh it's no where near 150mm (unless the installer has baby hands), I'd wager the squares printed on the back are around 50mm which could possibly make the roll around 300mm

3.53 not looking good???

[@pasisovi]

cheap solution, not long lasting though
