Troubleshooting

Compound not leveling properly.

Ensure the mix ratio of water to compound is correct. Check for any obstructions during application. Use a gauge rake or trowel to assist with spreading.

Slow drying time.

Ensure proper ventilation in the work area. Check the ambient temperature and humidity levels, as these can affect drying times. If the issue persists, review the mixing instructions and ensure that the correct ratio of water was used.

Cracking after drying.
