The Brick Kiln Repair Kit is not meant for deeper cracks or cracks that go all the way through the brick. If your firebrick is cracked all the way through, or looks structurally unstable, then that brick should be replaced immediately.\u003c\/p\u003e\n\u003cp\u003eIf the label comes off of your containers, and you are unsure of what the materials are, you can look at the color to determine what material it is. The brick cement is white, the brick powder is white, and the brick facing material is an off-white tan color.\u003c\/p\u003e\n\u003cp\u003eNOTE: This brick repair kit is ONLY meant to be used on L\u0026amp;L kilns.

Mix the ingredients with a small spatula in a container (like a glass jar or plastic cup). Mix in the following:\u003cbr\u003e ½ cup firebrick dust\u003cbr\u003e ¼ cup water\u003cbr\u003e 1 tablespoon Phosphate Cement\u003c\/p\u003e\n\u003cp\u003eCAUTION:PHOSPHATE CEMENT:\u003c\/p\u003e\n\u003cp\u003eThe special cement that is used by itself and with the grout is a phosphorous based cement. It has unusually strong adhesive properties which makes it ideal for repair work. It is different from the cement we normally use for cementing our firebrick. The phosphorus makes phosphoric acid. It is best to use rubber gloves. Be sure to wash your hands with soap and water immediately following your use. Phosphoric acid is very hazardous to your eyes. Protect your eyes with glasses while using the kiln repair cement.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eBRICK REPAIRS\u003c\/b\u003e\u003c\/p\u003e\nAPPLICATION OF BRICK HARDENER\u003cbr\u003e\n\u003col\u003e\n\u003cli\u003eFirst brush and vacuum the surface of the brick clean to remove any loose material or crumbling firebrick.\u003c\/li\u003e\n\u003cli\u003eNext wet the brick surface lightly.
