Does tuckpointing lead to efflorescence?
I used to have a specific info sheet on efflorescence, but am not able to locate it right now. I worked for builders for the last 12-15 years so the question came up often. Basically what it boils down to is that it is a natural occurrence in concrete products. Drive around any newish neighborhood and look at the brick and stonework, you will see examples everywhere. It will go away on its own eventually, or you can try having it brushed or cleaned but this will not be 100% successful. I’ve never known of a way to avoid it. Sorry to be so technical…ha ha! I would talk to the contractor about it, perhaps he will work with you under warranty.
