Pouring Liquid Glass before the underlying acrylics cure can cause undesirable bubbling to occur underneath the surface of the Liquid Glass. This is because the acrylics underneath off-gas as they cure which creates these trapped bubbles. A curing period of probably 72 hours is recommended before applying Liquid Glass depending on the thickness of the paint.

Yes you can, and you can even paint in between these layers to create a really interesting layered effect. Please note the curing times that we advise between layers of roughly 72 hours depending on the thickness and humidity of your area to prevent any formation of bubbles.

We recommend avoiding application of Liquid Glass over any products that contain PVA or other water-resoluble resin like watercolours, wood glues, or spray paints. Liquid Glass can develop cracks in reaction with water-resoluble materials as these materials prematurely suck the moisture out of Liquid Glass causing an undesirable cracking effect. We recommend to test your methods before application to ensure that Liquid Glass is compatible with the materials that you are using.

Liquid Glass will typically be dry to the touch after 24 hours, however this could be affected by the humidity in your area. If you are under extreme humid conditions it could take much longer for Liquid Glass to dry. It should also be noted that while Liquid Glass might be dry to the touch it will cure and harden over time as additives cure out of the product.

See some steps below.

We don't recommend adding water to this product as it can greatly affect the glossiness and finish. Adding water can increase the chances that crazing will occur.

It is best to stick to traditional art material substrates like canvas, or wood panel. Liquid Glass is not a perfect alternative to two-part epoxy resin products so it may not be compatible to apply over every possible substrate. We recommend testing your method before moving on to final projects for different applications.

It is not food safe, please use liquid glass for decorative purposes only.

Liquid Glass can resist some heat but it is best not to use Liquid Glass for higher heat applications like trivets. Liquid Glass can withstand the heat of a hot coffee mug for example so can be good for coaster projects, but there is a chance that rings can develop on the surface.

Please contact us if your Liquid Glass has developed a strange consistency, or has developed "lumps". Liquid Glass might over time develop lumps which can negatively impact its performance. There are two ways that you can try and remove these lumps:

1. shake the Liquid Glass container and the lumps may reincorporate into the liquid glass and act as normal
2. you can use a strainer to filter these lumps out.

Why do these lumps develop? This seems to occur over time especially under high humid and heat conditions. While not a common occurrence but it seems to especially occur during hot Summer months.

As Liquid Glass is 100% acrylic polymer emulsion it is a completely UV stable product. There is nothing in Liquid Glass that will cause yellowing over time. If you experience yellowing there can be cases where a chemical reaction takes place between the substrate and the Liquid Glass, but this is not a common occurrence.
