All surfaces should be smooth, clean, dry and free from frost, oil, grease, condensation
and other contamination. UniSeal in fillet applications should be applied prior to the
application of the self-adhesive membrane.
Application temperature should be above 5oC although the product has been proved to
work at 0oC.
Gloves and suitable PPE should be worn prior to application.
