Unfortunately, this happens when the lids have not been securely placed back on to the Paint Stick. Please ensure when you put the lids on your Paint Sticks, they click fully into place. As when the lids are not properly clicked on, there is a slight gap between the lid and the barrel of the Paint Stick, which allows air to access the barrel, and dries out the solidified paint which causes this issue to happen.
Our range of Paint Sticks are extremely versatile and can be used on a range of surfaces. Paper, wood, card, canvas, pebbles, leaves,tinfoil and many more! However, once painted on these surfaces, these will absorb into the material and will not be able to be removed, they will provide permanent coverage.
Paint Sticks can be used on a range of porous surfaces such as glass, windows, mirrors, whiteboards- any porous surface Paint Sticks are painted on can be removed by wiping off with a cloth and water.
Paints do stain. It is strongly recommended that all surfaces and clothing are protected whilst using Paint Sticks.
