Any form of adhesive can be applied; typically most adhesive formats are acrylics, solvent acrylics, hot melts and water (aqueous) based. Heskins only produces using modified solvent acrylics, although these adhesive formulations are more expensive, they are the best; high grab, high long term bond, great temperature resistance and does not age quickly. Hot melt adhesives do not like cold weather, they also soon degrade. Water based adhesives have poor performance and break down with water. Acrylics have poor initial grab.
