Easy to use, works as expected!
Applied cement with a putty knife after wetting both pieces. Dried quickly and darkened after firing. Very responsive customer service. Highest recommendation.

Kiln surface repair
I was surprised at how small the cement was, but it more than covered my kiln floor.

hey Evenheat..... how about instructions?
As others have mentioned there are no application instructions. Not all refractory repair cements are created equal so it'd be handy if Evenheat would include 'how to use instructions'. I did reach out to Evenheat and they emailed a .pdf almost immediately, so it'd be a good idea to do the same. Outside of that, it seems to have worked okay for my purposes. As with most of these products, it helps to wet the surfaces being repaired, and don'y apply too thick. Build up in several passes if over 1/4", after first application has dried and been fired.

Too expensive
Yes, it served it’s purpose but extremely overpriced

Great product
As novices, we really messed up the kiln and thought we would have to buy a new one. It needs to be done more than once because we created huge craters but it did it. Worth the high cost

Used it to repair a ceramic kiln mold
It came readymade. I stirred it with a popsicle stick and spooned it into the underside of my ceramic mold. It’s worked perfect since with no new cracks.

Applies easily using a putty knife or similar flat blade and can be smoothed or applied with the fingers if needed. Dries to the touch in a hour or so and adheres well. Works a charm. It does have a darker gray color, darker than the standard fire brick in our kiln.

use only if you want to ruin your kiln
There were no instructions included with this product. I covered the cracks in my kiln and it left a mess, with the bits of cement (product) dislodging during firing and ruining countless batches of glass. I've tried to get it off, but it is still (10 firings later) is leaving tiny specks of cement on my fused glass.
