We recently had a friend visit us who stood awkwardly on one of our slate steps leading to our front door. The friend was fine, but the step, well, not so much. The slate must have been very brittle and large chunk came away.
Not really sure what to do, I popped down to our local hardware store and spoke to our go-to guy there who recommended an extremely strong adhesive for this job: The Works by Geocel.
What this video to see whether we were able to successfully glue a slate step back together again.

While the repaired step was doing well, we accidentally stood on it, and the repaired area gave way. So while it’s strong, it’s not strong enough to take pressure from a significant weight.
