Great quality and great colour
Great quality, perfect dark brown colour. We have dark wood panels on the kitchen ceiling with spotlights. There was a tiny gap between the two of panels which the light was coming through that gap and didn’t look nice so I wanted to fill that gap. This brown sealant was perfect , exact brown colour i was looking for ,went on so smoothly and has no smell. Very happy with my purchase.

OB1 Black Multi-Surface Construction Sealant & Adhesive
I used the "OB1 Black Multi-Surface Construction Sealant & Adhesive" to stick down corner trims and seal the edges of my van lining that I did. The silicon had good adhesion for the trims I was sticking down and it was very workable. It does not set too quick and did not skin over at all so I was able to get a nice finish to it without ridges or the "dragging effect" you sometimes get when silicons start to skin over. This silicon was also pretty odourless. My tube came with a nozzle also.

One tube manybuses
All in one sealant, filler, mastic. Flows smoothly as a filler, mastic. Acts as a glue as well. Sandstone colour is a light cream beige so blends well

Sticky and took dark for oak
As an adhesive this is great and sticks amazingly well, as a sealant it's very hard to work with as very sticky. FYI colour doesn't go well with a IKEA oak coloured worktop. Value for money I would say good
