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

For the price point, I have been thoroughly satisfied with this product. Its medium modulus provides excellent flexibility, which was a critical factor for my extensive panelling project - it worked like a charm. The 290 PSI lap shear strength for wood-to-wood applications proved more than sufficient for the job at hand. My decision to purchase was reinforced by several positive YouTube reviews, which ultimately served as a deciding factor given the scale of my work. While I have not tested the product as a sealant, its performance as an adhesive was outstanding. Note for users: The product does have a strong odour; adequate respiratory protection (a mask) is strongly recommended during application.

I broke the corners off two raised patio slabs and rather than chip out and re-lay I used Stixall to put the pieces back in place. I made a little jig to clamp them in place and after a few hours, I couldn't move them by hand. I cut off the excess with a blade and it was like hard bathroom sealant. I got white instead of clear by accident, so not the prettiest repair but so far it looks rock solid. Stuck pretty quickly at initial placing too making life easier. Will find plenty of uses for this.

This is definitely the best contact adhesive of this type I have purchased, well priced and sticks brilliantly.

Seems to work pretty good on the first project. You have to move pretty quick. Sets good.

My go to sealant and adhesive for anything uPVC namely windows and doors. Also used it successfully to fill a gap between my front Aluminium windows and concrete ledge. Brilliant instant grab, waterproof and hard waring . You don't get a great deal of time to get a smooth finish as it forms a surface skin in about 10/15 mins (dependant on temp). A selection of colours to blend with most standard uPVC windows and doors. Its feels like a quality product when you are applying it.

Absolutely superb product. Tube is easy to cut end off (some are super tough to cut and use) IT applies easily and smoothly, once pressed on the wall it sticks instantly with no drooping or sliding, If pressed hard it maintains that pressure. It dies super, super strong and fortunately gives about 15 mins of 'movement' time where you can still make minor adjustments as you do other parts. One tube goes a long way, used 1.5 tubes to do this entire hallway. Absolutely superb product and fantastic price

Good quality and works well.

I used this to stick acoustic panels to the wall & it worked really well. Gives you enough time to get the panels lined up before it goes solid. Highly recommended.

Tres bon colle . Bonne adhérence

Impossible a sortir du tube! (ouvert le lendemain de la reception du colis) Pourtant j ai un pistolet a cartouche. l application de la colle est un cauchemar... Apres, c est vrai qu elle colle bien. A voir sur le long terme...

Le produit est arrivé rapidement, mais il semble être un vieux stock car il ne s'extrude pas du tout facilement avec un pistolet à. cartouche

mpossible a ejecter le mastic .sur la cartouche il est inscrit 2012

Acheter pour colmater une fissure sur ma piscine...la cartouche est arrivée endommagé et quasiment sèche à l'intérieur !!! J'ai pu retirer l'équivalent d'une cuillère à café !! Dégoûté pour le prix !!!
