when you add part b to part a make certain that you use a spatula to scrape out all of part b as the two parts are measured quite accurately. If you just pour what you can of part b into part a and leave it at that there will not only be quite a bit of waste but also the epoxy might not set properly. I have seen this happen with several two part epoxys before. Same as everything though use common sense and follow the rules and there are no issues.

IMO even the low laitance (skin free) screeds need to be sanded as the primer is relatively viscous and you will need to open the screed surface to encourage penetration. That said I have seen this one used many times without any issues what ever.
