Are cork coasters waterproof?
We have a lot of questions asking about our custom pet portrait coasters and if they will get ruined from being used as coasters. So let's dive in to how to care for your custom pet portrait coaster.
Will condensation from a glass ruin the cork on my custom coaster?
No, condensation from a glass will not "ruin" a cork coaster because cork is designed to absorb moisture, making it ideal for catching condensation from drinks; however, if a cork coaster is constantly exposed to large amounts of liquid, it can become saturated and potentially warp or deteriorate over time.
Key points about cork coasters and condensation:
- Natural absorption: Cork's structure allows it to readily absorb moisture from condensation without significant damage
- Preventative measure: Using a cork coaster helps protect surfaces from water rings left by condensation.
- Excessive moisture concern: While cork can handle normal condensation, consistently soaking it with large amounts of liquid can lead to issues.
