Please let your artwork dry for 6 to 12 hours. After it is fully dried, you may apply the ready mix grout provided by filling in the gaps between glasses and beads.
You should use a wet sponge to clean excessive grout that is left on top of glasses and beads right after applying the grout without letting it dry.
In case some of the beads fall, you may use a silicon-based clear glue or any transparent glue that is strong enough to keep the beads on your glass globe.
