Heads up on the new 'fast set' mortar from that big box store
I used to mix my own from scratch for years, but grabbed a bag of that pre-mix stuff for a small patio job last week to save time. It set up way too fast in the heat, about 15 minutes, and I had to toss a whole batch, costing me an extra $40 and an hour of cleanup. Anyone else run into this with the newer quick-setting products?
