Quote: No amount of sealer will stop it. To tell someone they can stop efflorescence simply by using the right magical sealer is just plain wrong and unscientific.
What the hell do you know about scientific? I know you believe you understand the subject matter, but you simply do not. I personally understand it on a molecular level. But I am sure you have a P.H.D. in chemistry as well. These salts and other chemicals (like free lime and free calcium and sodium hydroxide to name a few) you refer to are all part of the alkali family. THERE ARE SEALERS on the market that contain chemicals such as Dimethyl, Methylhydrogen siloxane, and N-Octyltriethoxysilane, and Fluorosliane/siloxane, as well as lithium, potassium, and sodium silicates. These chemicals seek out and react WITH the "salts and other chemicals" to form a seal inside the cementious material that is invisible. They use the very cause of efflorescence, and neutralize them and use them as a CATALYST for the sealers themselves and BLOCK THE EFFLORESCENCE PERMANENTLY.
While I am sure that with your vast knowledge of all that is in the universe, you will disagree with me I actually DO understand the science behind it. I have been developing these types of products for years and would gladly provide the names of some of these products outside this forum (rules you know) to prove that they do in fact work and work well, but the exercise would be futile, as you are clearly too closed minded to believe that modern science can advance on anything beyond your limited closed minded imagination. Early last century people told Henry Ford that Mass Production of Automobiles was impossible as well. With that said I imagine you still ride a horse because you dont believe in scientific advancement, but again, just because you have a strong opinion does not mean you are correct.
