Why is the glue still tacky?

Too Cold – Most resins will not fully cure when temperatures or the stone drops below 50°F causing it to stay tacky.

Air Entrapment – Sometimes when air is whipped and trapped into the resin mixture it can stay tacky.

Contains Moisture – Small or large amounts of moisture in the resin mix or in the stone can cause it to be tacky

Keeping it Past Expiration – Always check resin’s shelf life, old material can stay tacky.

You Mixed it Wrong – Incorrect mix ratios with some resin’s cause soft spots and tacky surfaces.
