It does exactly what it says on the tin
This is my second purchase. It is absolutely amazing. I have tried too many other products to mention and all a waste of money. I have sealed a cast iron outside pipe, no problem. Moulded plastic to metal. There really is no limit to its ability. Highly, highly recommend. Don't waste your money on products that promise but do not deliver. Setting time is speedy aswell. Thank you one million times.

Tough Epoxy Filler
I used this filler to repair holes and cracks in my asphalt floor which were caused by carpet gripper rods. It worked perfectly, although it is quite hard to use. You need a strong metal trowel to apply as the filler is extremely thick, almost like putty. The colour was a dark grey which blended in quite well with the black floor.

Early days but seems effective
Very easy to use and effective. Delivery was very quick Don't get a tremendous volume to use. Will need to see how long it lasts as only used 4 days ago.

Evil stuffb
It eventually dries rock hard, but, gosh..... it’s like trying to mix bubble gum! Not easy to use as it sticks to everything, gloves, adapter and anything that gets in its way. Be sure to wear gloves and use is small quantities.

Exactly wat I need
I used this to repair a rotten piece of ood once I cut out the old stuff. This was easy to mix and apply. The paste stuck well to the wood and was solid once hardened.

Great for pottery repair!
repaired a wax melt dish that had a piece missing, waited 24hrs sanded it down and painted it, dish is 100% repaired :) Just remember to mix enough together to avoid having too much or too little of either epoxy or hardener. Its hard to measure in small ammounts!

Boîtes minuscules
Produit arrivé dans ma boîte aux lettres dans une boîte complètement ouverte. Je ne m'imaginais pas non plus qu'il y ait aussi peu de produit ; les boîtes sont minuscules. Il y en a à peine plus que dans un gros tube de colle. Bien fait pour moi j'aurais du regarder plus attentivement la contenance. Pour du modelisme ça va... pour un bateau c'est autre chose.

Strong Epoxy That Really Gets the Job Done
Strong Epoxy That Really Gets the Job Done This is one of those products that every DIYer or homeowner should probably keep around. I’ve used a lot of adhesives and repair products over the years, and this epoxy feels genuinely heavy duty. Once mixed, it forms a thick paste that stays where you put it instead of dripping everywhere, which makes it especially useful for vertical surfaces, cracks, chipped areas, masonry, tile, or odd repairs around the house. What I like most is the working time. You’re not rushed like with fast-setting epoxies, so you actually have time to shape it, position things properly, and make adjustments before it hardens. Once cured, it feels extremely solid and durable. I also appreciate that it can be sanded and painted afterward for a cleaner finished look. I found it especially useful as a filler as well as an adhesive. The thick consistency makes it good for rebuilding missing material or filling voids rather than just gluing two surfaces together. A few things to keep in mind: this is definitely not a quick-fix epoxy. Cure time is on the slower side, so patience is required. It’s also thick and a little messy to mix, so gloves and a mixing surface are a good idea. Surface prep matters—a clean, roughened surface gives the best results. Bottom Line: If you want a strong, versatile epoxy for serious repairs and don’t mind waiting for a full cure, this is excellent stuff. Not the fastest product, but very strong and dependable once it sets.

Love this stuff
Love this stuff. I have used it multiple times now. Able to mould it several hours after application, which is great to get it exactly how you want it.
