Review on 🔥 GIRTech CONTACT 40 Fireplace Furnace Cement by Lokesh Das

I used this to attach the bricks to my chimney walls. Let it dry for two days and it will become solid concrete. To my surprise, after three runs there are no cracks, the previous mortar from other brands had to be sealed after the first run. It needs to be stirred thoroughly, but it sticks to the walls very well and almost does not drain. Loved it, will definitely use again.
