Hotter months can bring
added problems with installation & treatment by sub-trades of Chemind
We highlight some of these issues below:
Topcoats dry/cure more quickly
particularly water based, may skin over or dry very quickly
process may be disrupted
sub-trades may be delayed
working time of two-part products and mixed ceramic tile adhesives is shorter
Damage can be
caused by summer-storms
To minimise application
problems and site issues, we recommend the following:
For water based
products, in hot or windy conditions, add up to 10% clean water to aid
application. This is particularly for primers and to reduce over-lap shear
“roughness”, on high-build coatings.
of water based membranes to hot substrates and in direct sunlight.
Hot substrate and
hot conditions exaggerates outgassing, pin-holing, bubbles and blisters.
membranes to decks is best done very early in the day, before heat and
outgassing become a problem. Alternatively work in the shade if possible.
may increase membrane surface tackiness of liquid membranes – broadcast fine
sand or cement dust to block this tackiness, if needed.
Mix only an
appropriate amount of two-part membrane, coating or cementitious adhesive
product that can safely be applied, before it becomes unusable.
