Sika 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.

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.

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!

I used this to stick a Roman nose cover over a cable penetration through an external wall. It stuck it to the brickwork and formed a good seal. Recommended.

Nice item , as described and better.

Like they say does what it's says. Works well in and around the house. Seals well.

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.

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.
