## Description

CaribSea Rock Lock 2 Minute Cement 500g (17oz) for Corals and Rocks

Review: Works, great stuff - First time using, great product! If mixed properly with the 3:1 ratio it shows on the jar and in small batches it mixes and works perfectly. It does set fast so already have your pieces set up to cement and work fast. You can add 1/2 tablespoon of lemon juice to your mix before you add the water and it will give you a few extra minutes of work time. A second set of hands helps too. I mixed batches of 9 tablespoons of powder 3 tablespoons of water 1/2 tablespoon of lemon juice.
Review: Disappointed - No tried very small batches no luck Rick fell and broke Want recommend

### ⭐⭐⭐⭐⭐ It's legit! Holds like a brick in 5 mins!
*by L***R on February 9, 2025*

It holds like a brick. Only trick is mixing correctly and fast. Just use very little water at first. Mix some tiny batches or else you will waste it! But it says 2 mins for a reason lol 😆 also just dab on with gorilla glue gel on both sides of the rock. Sandwich this between and it's like a solid rock!.
