Stormdry Express Mortar cures by evaporation of moisture. In cold and damp conditions this drying process can be slowed, especially when applied in thick layers. For thick applications, it may be necessary to apply the mortar in two layers to achieve an even cure. When applying the second coat push the mortar into the first coat for a good bond. Always read the technical datasheet before applying.
