it is important to maintain a good waterproof or paint coating on all fibre-cement. Water entering fibre-cement can cause swelling, delamination and eventual failure of the material. Fibre-cement can also act as a moisture ‘reservoir’ and cause an increase in moisture loadings within the wall. This would lead to rapid deterioration of the structure if not remedied.
