I had a fairly recent concrete repair project at my house that, for lack of better terms, fell apart before my eyes. I didn't trust the contractor to repair, but eventually determined it was the bonding agent, and was referred to Larsen Products. I spoke directly with the owner, Jeff Larsen, who walked me through the issue I had, and how Weld-Crete worked and could help.
He was professional, extremely knowledgeable, and the concrete repair has had zero issues since. If you want to avoid repairing a repair job, make sure your contractor isn't cutting corners and using subpar materials. This stuff works.

I purchased countless gallons of Plaster Weld and recently received one that had frozen. I spoke with the owner of the company, Jeff Larsen and from the onset he was rude, unprofessional and extremely defensive. Instead of taking any accountability, he said there was "no possible way" that "anything could ever been wrong with Plaster Weld". Quite a bold statement to claim that he is the first manufacturer ever in history to make a perfect product.
The customer service speaks for itself. Feel horrible for the employees of Larsen Products who have to experience that narcissistic and childish behavior daily. I will be certain to never purchase another product from Larsen Products ever again.
