Stixall Extreme Power Sealant and Adhesive, Waterproof, Crystal Clear, 290 ml

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.

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.

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.

Great value for a great adhesive

Arrived promptly in time for my job. Excellent stuff. Easy to use. Reliable and strong bonding. Great that it can be used in the rain!

Really good stuff used for adhering accessories in bathroom. Works well but read the instructions.

Not as grippy as Gripfill but good adhesion. Carefull not to get it where you don't want it as it's hard to get off, as you would expect.

This is an amazing product and works exactly as described, super strong and reliable. My only gripe is the packaging. I personally prefer the small tube version with a resealable lid as I really dislike using a caulking gun for small jobs. No matter how well I try to reseal the larger tube, the product never seems to stay preserved for next time.
