The ibd LED/UV Bonder is a non-acid primer for natural nails. It promotes excellent adhesion for all types of ibd LED/UV Gel applications. As ibd Bonder is non-etching it is gentler on nails than traditional acrylic primers. Apply sparingly and cure under a UV or LED light for one minute then apply your ibd gel product directly on top. Cure time: 1 minute. in UV and 30 sec in LED lamp.
