What can i do with concete sealer that is tacky?

If your concrete sealer is tacky, it may not have cured properly due to high humidity, inadequate ventilation, or applying a second coat too soon. To address this, you can try increasing ventilation to help it dry, or use a solvent recommended by the sealer manufacturer to wipe away the tackiness. If the sealer remains tacky after these attempts, you might need to strip it and reapply a new coat, ensuring to follow the manufacturer's instructions closely. Always conduct a small test area first before applying any solvents or new sealers.
