Adhesives
The construction industry is constantly developing a vast spectrum of adhesives and sealers, some of which can be suitable for use with roadplates.
However serious thought should be given to how adhered plates will be released at the end of their use and how both the plate and the affected areas can be restored. Also, sealants and glues with a silicon content are best avoided as they have shown to have a detrimental effect on metals by the way of promoting accelerated rusting and corrosion.
