Used to fix chiminea

Used to fix chiminea
I barely had my chiminea a year and the top got knocked over and had broken into pieces. I tried this stuff and hoped I could salvage my chiminea. I actually bought two tubes but only needed one. I tried to keep the thickness closer to 1/8" and no more than 1/4" thick. At about 15% into the project I remembered that I needed to wet the cracks before application. So I used a spray bottle with water. I allowed to dry 24 hours and then applied more to areas that showed some small gaps. I waited another 24 hours to dry. I took a green scouring pad (I didnt have sand paper) to smooth out rough edges. I left it out in California sun to further dry aboyt 4 hours. Then went through the curing process of heating it under <200°F for 30 minutes and then >500° for about an hour. Most areas looked good. I had some minimal bubbling. I think maybe I needed to cure longer at <200°. Final step was to paint. I think it turned out pretty good. It saved me from having to buy a new chiminea. We shall see how it holds up. I'll update within the next year.

5.0 out of 5 stars Bueno para tapar ranuras en el calentador
Reviewed in Mexico on January 2, 2021
El calentador, al prender salían flamazos de entre las piedras cuando se ponía en temperatura media o baja. Este calentador en particular tenía una especie de cemento blanco entre las piedras, este cemento se fue rompiendo poco a poco y se caía en pedazos. Este producto esta diseñado para soportar temperaturas altas de fisuras en chimeneas. Seguí las instrucciones para ponerlo ... mojar el área donde se va a aplicar, dejar secar 24 hrs y curarlo al prender el calentador. Funcionó perfecto ya el calentador funciona sin problemas. Se ve un poco feo porque es de color gris y no encontré color blanco, pero con lo que costó no me compro un calentador nuevo. Sobró bastante producto, fue en realidad muy poco el que utilicé. Cuando se cura el color gris obscuro se va poniendo mas claro.
