It's better to apply / wet the surface with latex admixture, let it dry before apply primer and top waterproofing membrane. Last much longer than without or seal the crack with crack sealer such as Sikadur-20 Crack Seal.

QUOTE(abm @ Aug 8 2021, 08:53 PM) Thank you for your reply. Try SikaCoat 500 SuperI read from manufacturer's recommendation, to strengthen the coating, lay a layer of fiberglass mat in between the coat. Is there a specific type of fiberglass mat for this or any fiberglass mat will do?  Attached thumbnail(s)
