I'm trying to slow moisture transfer, effervescence and dusting on brick basement interior walls. I've done what I can to regrade and drain outside but get moisture in the corners where there's old mortar/dirt between layers I think that don't dry well and show darker on the brick where it's been lime mortar repaired. (Like a sponged on german schmear.) Would this product be good for this application? SAMPLE - AFM SafeCoat, WaterShield Concrete & Masonry Sealers

No, a better product would be our GBS Penetrating Concrete Sealer. This will stop dusting, efflorescence, spawling and other issues because it seeps deep into the concrete and chemically bonds. This fills the microscopic pores and prevents moisture intrusion. However, this can only be applied to dry concrete. If there is moisture present it will prevent this sealer from soaking in deeply. You may have to wait or increase the heat, use fans or other means to dry it out. Drier the better. This product requires multiple applications, one after the other; usually 3-5. The surface must be clean, free of other sealers or paint and it must not have been polished or power-troweled which inhibits penetration. Please refer to the installation guidelines for more details. One gallon will cover about 200-250 SF including multiple coats.
