Frequently Asked Questions

What is No Leak Concrete Sealer?

No Leak Concrete Sealer is a professional-grade sealer specifically designed to protect concrete and Hydrostone vessels from wax leaks. It was developed by a paint chemist to provide an effective protection for candle makers and artisans.

How is this product intended to be used?

The sealer is designed for use inside decorative concrete and Hydrostone candle vessels to reduce porosity and help prevent wax leakage. It is water based, is not classified as a flammable liquid, low odour and dries clear. It is not intended for direct contact with flame, burning wick or sustained heat, and does not replace proper wick testing or standard candle safety practices.  It is formulated with careful consideration.  

How do I apply the sealer?

You can use either the pour method or dip method. Pour the sealer into your vessel, let it stand for 1 minute, pour out and let drain for 5 minutes. Wait at least 30 minutes between coats. Allow 72 hours (3-4 days) to cure before filling with wax.

How many coats do I need?

Typically, one coat is enough for effective sealing. A second coat can be applied if desired, with at least 30 minutes between applications.

Can I reuse the sealer?

Yes! Pour used sealer into a clean, separate container for future use. Never return used sealer to the original container.

What temperature should I apply it at?

Best results are achieved in temperatures between 15°C and 27°C (60°F–80°F). Allow your piece to cure in temperatures above 15°C (60°F) with humidity between 35–50%.

Will it change the look of my concrete?

No! The sealer absorbs evenly and brings out the natural beauty of the material without altering the look or feel.
