Stixall Extreme Power Sealant and Adhesive, Crystal Clear, 290ml | Waterproof – Can Be Applied Under Water – High Initial Grab

I’ve been using Sika Stixall Extreme Power for a few jobs around the house, and it’s lived up to its name. The bond strength is impressive – it grabs quickly and holds firm even on tricky surfaces. I’ve used it to fix skirting boards, seal around pipes, and stick down trim, and it hasn’t let me down. Application is straightforward with a standard sealant gun, and it doesn’t slump or make a mess. Once cured, it stays flexible, which is great for areas that get a bit of movement. The fact that it works on damp surfaces is also a big bonus compared to other adhesives I’ve tried. It’s not the cheapest option, but you can feel the quality. For anyone needing a strong all-in-one adhesive and sealant, this is a reliable choice.

Nice glue to apply, and sticks everything well, and good for outdoor working.

Why did you choose this product over others?: Good all rounder, as you can use it for caulking and "low strength" adhesive tasks. It can skim over very fast in hot humid conditions, and is unforgiving of tooling, you've got one chance and attempt at correcting it has gone awry for me. Usually I tape to prevent excess and then if j need to bevel with a silicone caulking tool then quickly remove the tape. In very hot humid conditions the tape can catch the skin of caulk line and ruin your day. Genuinely fantastic as substitute for decorators caulk, doesn't shrink, sets to the density of firm silicone caulk, so for coving, skirting along with a few fixings and rag its amazing. Can even be capped and re used, though a caulking gun with enough oomph to power through any leak in the back of the tube is a good idea. And you may need to dig out whatever has set in the nozzle if you've cut it fair close to the tip.

I tried just about everything to get my bathroom mirror to stay up, and nothing seemed to hold—until I used Stixall. This stuff is incredible! It bonded quickly, held firmly, and gave me total confidence that the mirror wasn’t going anywhere. Easy to apply, super strong, and truly reliable. After struggling with other adhesives, Stixall definitely came through. Highly recommend

This stuff is fantastic. It's really flexible and sticks really well. Especially good if you can press the pieces together across flat surfaces but I've stuck all sorts with it. Tiles, timber, acoustic panel edges, around sinks in base units (although doesn't finish like silicone) but sticks the sinks in really well. The clear one is brilliant and I would recommend it. Worth 6 stars.

It works a treat . Would recommend

I used this to install those Nordic acoustic wall panels (wood strips mounted to foam backing), to bare plaster. It had a great grab given that they’re really quite heavy. I was able to immediately reposition them before pressing down into their final position. Months on, they’re absolutely solid. I fully anticipate wall damage if I tried to remove them, but was aware of that before I started.

Not very good as an adhesive but okay for sealing a shed roof

Works great

Worked on Styrofoam to Styrofoam. Did not work as well on Styrofoam to steel. Found same results with 2 other brands from big box store.
