Customers praised this kiln shelf primer for being "easy to apply with a great smooth finish" and cost-effective compared to alternatives. Most found it prevents sticking when applied correctly in multiple thin coats. One customer initially experienced flaking, but resolved it by applying thinner layers instead of thick coats.

Perfect!

Does the job perfectly - applied even coats in multiple directions (as per instructions) and haven't had any issues with sticking. Great product.

I didn't give the kiln wash a very good review because it flaked off. Your team got back to me, and it was my fault because I was applying it far too thickly. Thank you Warm glass. I now apply multiple thin coats and it works brilliantly.

I have applied the shelf primer to my kiln shelves but each time, once dried, it cracks and flakes off. I have tried both kiln drying and air drying but it makes no difference. Please could you tell me what I am doing wrong.

I use this in my microwave kiln, on the base, and on kiln paper(I made mistake of purchasing a bulk pack of round papers,online,bargain price, or so I thought!!!! BIG mistake) but coupla coats of this on top of them, makes them usable.
