I always use the Aluminum 10610 Devcon ... It's 4-1 ratio by volume, 4 teaspoons of resin to 1 teaspoon of hardener. That's more then enough for a full pillar bedding job. I like it a lot better.. much easier to work with after it has set and much lighter... Make sure to always warm up in warm water and the resin needs to be mixed before measuring. It tends to settle.. I use a piece of bucher paper taped to a small cutting board , slick side up to mix..
The Steel 10110 Devcon is great stuff just get a system to make your measering stress free. If your off a little bit it will still set up. Your mess up should be removed... Good luck with the next try...
