What do the phrases "does not support the growth of mould" and "resistant
to moulds" mean? Do they mean you will never see mould on such surfaces?

"Does not support the growth of mould" means there's no acetate in the
sealant, acetate is the growth medium for mould.

"resistant to moulds" means that unlike silicone, mould doesn't grow in the
body of the sealant. If you look at mouldy silicone you will find it
impossible to clean off the mould because it penetrates into the sealant.
Hence rubbing at the surface will not clean it. With the Evostick
co-polymer sealant and tiwh Sikaflex mould may form on the surface in damp
conditions but it can be wiped off with a cloth.
