Sarah Mae wrote:Hi Andrew. I dont know if it works. I have it bookmarked because I have been collecting (real) tin cans for the past six months to make tin tiles for a roof- probably of an outbuilding. This tin is coated, but it will eventually lose that coating, I am sure, so I had thought of using this product when it becomes necessary. The added benefit is that I could use the roof for rainwater catchment. So, if you try it, you can let us all know if it works! Haha.
most builders yards have similar products extremely good if you re-coat every 3-5 years i have seen 30 year old tanks rust free only problem nowadays is painting in confined spaces
now you have a substrate for ferrocement.
get nylon fibers to mix into the cement. that allows you to use a thin lightweight layer without cracking.
the only drawback is that it is then an alkaline surface; but if you can live with that while you save money for a favorable sealer. we have acid rain living here by an active volcano so it can balance...I don't know what would be a good sealer...some claim safe for catchment...but they are selling it.
