What is the best quick set cement that is strong for moulds for candles and could someone please suggest a sealer to seal these moulds as they will be used to pour hot wax and later burning wax. Thanks
Hi @shamshah,
When it comes to craft projects like this, where cements and sealers are being used in ways they weren’t really designed for, it’s a bit tricky to give you a confident answer. You might actually be better off asking in a candle-making community, where people have experimented with similar projects and can share what’s worked for them.
You could potentially use something like a construction grout to make your moulds, as it’s strong and quick-setting. However, when it comes to sealing them, I’m not familiar with a product that's definitely suitable for the heat and conditions you'd get with pouring hot wax. You could try a standard concrete sealer, but whether it would hold up to the heat and wax, I honestly couldn't say for sure.
Please let me know if you have any questions.
Mitchell
