Does exactly what it says
Used to fix a loose handle on the kitchen tap, upon finishing it actually feels solid as if it was welded there. Highly recommended for the right use

Value for money
You won't find a better steel 2 part glue anywhere. I've used this for years

Use a thick amount, and wait 48 hours to cure.
This was fit for purpose. I used it to repair a few different items and it holds strong once cured. Note: it needs to be applied thick; a thin layer will not hold. The 4-6 hour cure time is not sufficient for most cases. The first time I applied it to repair something, I left it alone for 12 hours, applied a medium thick amount, and it instantly unbonded upon using the item. Second time, I used an extra thick amount, bonded the broken plastic piece to an adjacent metal, and allowed it to cure for a full 24 hours in a hot environment. Voila. I would wait 48 hours to cure for optimal results.

Brilliant product
We have all sorts to fix edging onto composite Decking. This is the only one that has done the job. Others have lifted in a short time
