Floralock Stem Adhesive is used to lock the stems of flowers into wet foam. Fresh flowers can be very heavy - it is always a concern that a stem may slide out of a wedding or bridesmaid bouquet.
Floralock comes with a long red straw that fits into the nozzle of the can.
You use this long red straw to insert it deep into the bouquet so that the glue may be squirted directly onto the stems.
You should always shake the can thoroughly each time it is used, so that the glue will run freely through the straw and not clog up.
