Quality product!
Used to glue back on a cracked piece of my terracotta firepit , have used it 3 times since glueing back on and cracking has not returned, very happy with the product, and the price wasn’t too bad either

I am replacing the seal between the lid and body on my kiln. Can I use the liquid kiln cement as an "adhesive" to hold the new seal in place?
Bruce from United Kingdom
Yes this is perfect.
Scarva Team
What is the highest temperature this can withstand? Thanks
Thidaa from United Kingdom
The highest temperature this can withstand is approximately 1300ºC.

Hello.
There are no instructions with the product. How long should I let this dry before firing in kiln please ?
Fiona from United Kingdom
Hi there,
This will be ready to fire after a few hours. I would suggest firing slowly on the first firing to stop any excess moisture content from boiling out. 60°C per hour should be fine. After 300°C you can ramp up a little faster.
Hope this helps!

I purchased some of this white kiln cement
I have put some in my furnace and heated it to 250C.It has gone a grey colour !!
Do i have to heat higher to make it white ?
david daale from United Kingdom
Yes it will have to go to 1000oC to be completely cured.

Hi.
Would this product be suitable for repairing deep holes in bricks (25mm).
If so would it need to be put on in layers and allowed to dry before putting another layer on.
Thank you.
roger wilkinson from United Kingdom
Hi,
If you add Molochite 30s - 80s, 60s or 80s in to the mixture 50/50 you will not need to apply it in layers as it will account for the shrinkage.
Hope this helps!

Hi would this product be suitable to repair a cracked fire brick for an open wood/coal burning fire.
Simon from United Kingdom
Hi, yes this should be fine for your application. Apply and allow to dry for a few days before lighting the fire again as drying too quickly may lead to cracking the cement.

Hi, In the past I've used this, as recommended, to attach fiber glass insulation to my kiln door edge very successfully.
Could I also use it to fill in the rusty bits on the kilns surface, esp at the edges?
If not is there anything I can do to help the spread of the rust and fill any gaps?? Thanks
Gillian from United Kingdom
To help prevent rust which is increasingly hard as the kiln gets older you would be best treating it with an anti rust paint or sealer you will be able to get one of these from a good hardware store. It will help to an extent and prolong the life of the kiln but due to the high temperature and exposure to moisture the rust will persist.

Could I plaster a wall with it behind a stove? If so can I paint over it?
sean from Ireland
This cement is used for the repair of kilns I think there are better materials on the market for your application. I would suggest going to a good hardware store and asking their advice on a suitable product. Hope this helps.

Would this be suitable for a Prometheus pro 7 kiln?

Could you use this to reattach a piece of broken bisque ware?
Rosemary from United Kingdom
Hi, not really. You'd be better using one of the two products within https://www.scarva.com/en/Marx-Menders/b-77.aspx
Pick the temperature based on your final firing temp and follow the instructions provided with the product. Hope this helps!
Scarva Team
Why is the shelf life of this?
Elke from United Kingdom
This product has a shelf life of around 12 months providing it is kept air tight. Hope this helps.

I noticed a couple of cracks in the kiln bricks in my electric kiln. Is this the correct product to repair? Also, there are some gaps between bricks - would it be a good idea to fill them?
Sharon from United Kingdom
Cracks in kiln bricks are very normal and nothing to worry about providing the brick is held in place and not loose. The cracks are caused by the contraction between hot and cold, these cracks and gaps will expand and close as the kiln heats up so it is important to leave them alone. I would only recommend using the kiln cement to repair broken bits of brickwork or if brickwork was loose or damaged.
