How long does it take for Stormdry XR-Mortar to fully cure?

Troubleshooting

Mortar is difficult to extrude from the cartridge.

Ensure the nozzle is properly attached and the cartridge is correctly inserted in the mastic gun. Check for any blockages in the nozzle and clear if necessary. If the temperature is too cold, warm the cartridge before use.

Mortar is not blending with the existing mortar color.

Ensure the existing mortar is clean. If a color mismatch persists, consider a tinted mortar for a better match.

Mortar is cracking after drying.

Ensure the crack has been filled completely. For thicker applications, apply the mortar in multiple layers, allowing each layer to dry before applying the next.
