Warning: That mortar mix at the Home Depot in Spokane almost cost me a wall
I grabbed a pallet of their store brand type S mortar last month for a retaining wall job. After three days of curing, I noticed hairline cracks in the joints that just kept spreading. Turns out the batch had way too much air entrainment for structural work, at least according to the supplier I called. Has anyone else run into bad mixes from big box stores, or did I just get unlucky with that one load?
