Fine cracks appear soon after application.
Check substrate movement, mixing water, coat thickness, cure and exposure to sun or wind.
Overthick coats, rapid drying or an inflexible system on moving substrate can crack.
Treat active movement separately and select a suitable flexible or rigid system for the location.
Mix to stated proportions and cure each coat as specified; reinforce stress points if designed.
Inspect continuity and carry out adhesion or water testing in the approved plan.
Do not bridge an active movement joint with a rigid cementitious slurry.
