Incompatible Materials

When it comes to liquid applied coatings it’s important that you understand how to correctly apply them as well as making sure that the are compatible with the existing materials you intend to apply them over. In this picture it shows an elastomeric coating that was applied over an asphalt based emulsion. You can apply an elastomeric coating over emulsion as long as the emulsion has fully curd and the oils have totally burned off. If you coat it before its fully curd then the results down the road will look like the picture. Because the process was done incorrectly this home owner will be spending money on a new roof.
