So i have been trying to aquire som aluminiumoxide or zirconium paint for a while now. Lets just say..its a effin hassle.. So i went to my mothers, and dug thru her bags of weird as **** for pottery making. This is what i came up with. 95% Aluminiumoxide in 10 micron mesh 5% Kaolin powder in 10 micron mesh I did this by weight. And then i added in sodium silicate at about 3% of the total weight of the dry stuff. That creates as sticky paste. I then smeared onto my concrete. Now.. it would be better if this was more like paint.. But dont know if i can add water into this or if that will break the sodium silicate as a bonding material or not. |
