When the first coat isn’t sticky, the second coat can be applied, the first layer is recommended being applied in thinner layer for better releasing gas generated during reaction. The second coat should be applied in different direction to the first coat. The optimal coating rate is 2.0kg/m² for thickness of 1.5mm.
