This product can act as a very strong glue, waterproofing layer or fix cracks and chips on practically any surfaces. It has a coarse finish, so it is more suitable for exterior applications. Can be aanded, painted. I found it absolutely indespensible in waterproofing rooftop and my balcony. Once epoxy components are mixed you have about 1.5 hours to work with the mix. So only mix the amount you can consume in this timeframe. Cures in 24 hours. First 6 -8 hours it will remain soft and should not be touched. After 24 hours it is as hard as a rock. Highly recommend to use disposable gloves when working with this product. It is very sticky and can only be removed from the tools using a whitesprit (paint dissolvant) or acetone.

Looks like another great product from Sika. Unfortunately the seller shipped resin that had already leaked, wrapped it in plastic, and hoped that it would be ok. Very disappointing purchase.

Very good product

Good for repairing
