Rated 5 out of 5 by from WOW! Having just put a raised patio down with an open edge I wanted to "dress" the open edge to hide the slab edge and mortar base. After looking at options I settled for brick effect porcelain tiles 25 x 6cm but did not fancy fixing batons between all the balustrade support posts and using tile adhesive. Came across OB1 and the reviews were impressive - and correct, I fixed them all quite quick, a good edge bead with a "squiggle" bead through the middle, press firmly into place and hold for a few seconds. Tried a few and left then overnight - solid fixing - would not budge. Put the remainder up quite quickly, just held in place for a short while and moved on, an occasional glance back but none moved or slid out of place. VERY PLEASED. I found out that by putting a little extra on the top edge I could squeeze out a little excess which (the next day) could be trimmed with a craft blade so no need to grout any gaps, did grout between though and the colours matched. Would recommend.

Rated 5 out of 5 by from OB1 can seal thee Despite the poor attempt with my title pun I really can’t fault this as a sealant. An ongoing leak issue on two connectors with non standard guttering (full replace as no spares) has been driving me mad for months. Tried numerous sealants inc those designed for the purpose and all would fail within a few weeks either from expansion/contraction or adhesion issues. Carried out the clean and use with OB1 and a seal was achieved. More importantly it’s still sealed after frost, snow, hail and a few sunny & warm days (Love the UK weather!) Heavy rain will no doubt follow soon so hopefully it will prove itself again.

Rated 1 out of 5 by from Awful product - avoid ! The properties of this sealant are very different from a normal silicone sealant. Straight from a freshly opened tube the product does not 'gun' like a typical sealant (it's quite thick/dry) and it's incredibly difficult to shape neatly with profiling tools. The sealant seems to ooze an oil which spreads beyond the sealant (but which is difficult to wipe away) and the sealant itself spreads across the face of the profiling tools (leaving a wider bead than desired) rather than being neatly shaped as the excess is removed. Applying this sealant took far longer than normal, and the joints now needs to be cleaned/detailed to get the finish to the same level of quality as my other sealant work in the same bathroom room (Dow products). It's one of the worst products I've ever used. Definitely one to avoid.
