InChapala1 Posted November 17, 2022 Report Share Posted November 17, 2022 The salitre fix was done about 2 weeks ago and we haven't had rain since around Oct 22nd, so unsure how the walls might have been impacted by moisture? Quote Link to comment Share on other sites More sharing options...
chapalence Posted November 17, 2022 Report Share Posted November 17, 2022 This is what we do and we have never had salitre come back in an already treated spot. After thoroughly removing the affected concrete, usually about 2 inches deep, we use Sika AntiSalitre via a spray bottle. We wait a full week before first filling the area about 1/2 - 3/4 deep with Cemex Multiplast. When that has had time to dry we do a finish coat. Since the locals call salitre "rising dampness", I would guess that most salitre that occurs lower in walls both inside and out is not the result of direct exposure to rain, but moisture coming from the ground below. A friend suggested waiting to treat salitre until January or February to allow the moisture to finally abate. We don't always wait. 1 Quote Link to comment Share on other sites More sharing options...
CactusMike Posted November 18, 2022 Report Share Posted November 18, 2022 I didn't try the "secret formula" so I have no idea if it would work. I doubt anything would work. As far as I know, the problem is due to building walls that don't include a moisture barrier between the bottom of the wall and the foundation and, once it's built wrong, it's too late to correct it. 1 Quote Link to comment Share on other sites More sharing options...
